66-599: Rodale Institute uses a long-term, side-by-side research trial model to compare organic and conventional agriculture. Its longest running experiment, the Farming Systems Trial, has been running since 1981 and compares organic and conventional corn, soybeans, and other grains. The institute also researches the effects of growing food without chemical pesticides , herbicides and fertilizers on human health, water quality, climate change, and more. Collaborations with farmers and agricultural science peers throughout

132-558: A reference dose to determine health risk associated with exposure. Another challenge researchers face in deriving a reference dose is identifying health endpoints that are relevant to exposure. More epidemiological research is needed to identify critical health endpoints, particularly among populations who are occupationally exposed. Manure Manure is organic matter that is used as organic fertilizer in agriculture . Most manure consists of animal feces ; other sources include compost and green manure . Manures contribute to

198-428: A Rodale Press book editor in 1961, took over as president of the institute. Ardath Rodale became the institute's chairman. Anthony Rodale, son of Ardath and Bob, became vice-chairman. Anthony and his wife, Florence, developed outreach efforts for children during the couple's period of active program involvement before Anthony became an international ambassador for the institute. Board member Paul McGinley became co-chair of

264-435: A biochemical target, compounds described in patents or literature, or biocontrol organisms. Compounds that are active in the screening process, known as hits or leads, cannot be used as pesticides, except for biocontrol organisms and some potent natural products. These lead compounds need to be optimised by a series of cycles of synthesis and testing of analogs. For approval by regulatory authorities for use as pesticides,

330-664: A farm east of Kutztown, Pennsylvania . At the Kutztown site, Rodale and his wife Ardath established what is now known as The Rodale Institute to begin an era of regenerative, organic farm-scale research. The Kutztown site was listed on the National Register of Historic Places . It is also known as the Siegfried's Dale Farm . Rodale proposed the concept of regeneration to argue that any natural system, properly managed, could be productive while increasing its capacity into

396-645: A fertilizer for farming . It can improve the soil structure (aggregation) so that the soil holds more nutrients and water, and therefore becomes more fertile. Animal manure also encourages soil microbial activity which promotes the soil's trace mineral supply, improving plant nutrition. It also contains some nitrogen and other nutrients that assist the growth of plants. Odor is an obvious and major issue with animal manure. Components in swine manure include low molecular weight carboxylic acids, acetic , propionic , butyric , and valeric acids . Other components include skatole and trimethyl amine . Animal manures with

462-519: A particularly unpleasant odor (such as slurries from intensive pig farming ) are usually knifed (injected) directly into the soil to reduce release of the odor. Manure from pigs and cattle is usually spread on fields using a manure spreader . Due to the relatively lower level of proteins in vegetable matter, herbivore manure has a milder smell than the dung of carnivores or omnivores . However, herbivore slurry that has undergone anaerobic fermentation may develop more unpleasant odors, and this can be

528-538: A pesticide is a chemical or biological agent (such as a virus , bacterium , or fungus ) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens , weeds, molluscs , birds , mammals , fish , nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or are disease vectors . Along with these benefits, pesticides also have drawbacks, such as potential toxicity to humans and other species. The word pesticide derives from

594-401: A pesticide was first seen in the 1920s with inorganic pesticides, and later it was found that development of resistance is to be expected, and measures to delay it are important. Integrated pest management (IPM) was introduced in the 1950s. By careful analysis and spraying only when an economical or biological threshold of crop damage is reached, pesticide application is reduced. This became in

660-403: A problem in some agricultural regions. Poultry droppings are harmful to plants when fresh, but after a period of composting are valuable fertilizers. Manure is also commercially composted and bagged and sold as a soil amendment. In 2018, Austrian scientists offered a method of paper production from elephant and cow manure. Dry animal dung is used as a fuel in many countries around

726-793: A problem in terms of excessive use in areas of intensive agriculture with high numbers of livestock and too little available farmland. The greenhouse gas nitrous oxide can be emitted so contributing to climate change . In 2007, a University of Minnesota study indicated that foods such as corn, lettuce, and potatoes have been found to accumulate antibiotics from soils spread with animal manure that contains these drugs. Organic foods may be much more or much less likely to contain antibiotics, depending on their sources and treatment of manure. For instance, by Soil Association Standard 4.7.38, most organic arable farmers either have their own supply of manure (which would, therefore, not normally contain drug residues) or else rely on green manure crops for

792-455: Is becoming widespread and has been used with success in countries such as Indonesia , China , Bangladesh , the U.S., Australia , and Mexico . IPM attempts to recognize the more widespread impacts of an action on an ecosystem , so that natural balances are not upset. Each use of a pesticide carries some associated risk. Proper pesticide use decreases these associated risks to a level deemed acceptable by pesticide regulatory agencies such as

858-591: Is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, as horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. Chicken litter, coming from a bird, is very concentrated in nitrogen and phosphate and is prized for both properties. Animal manures may be adulterated or contaminated with other animal products, such as wool ( shoddy and other hair ), feathers , blood , and bone . Livestock feed can be mixed with

924-456: Is similarly challenging, yet well documented in developing countries. Because of critical development periods of the fetus and newborn children, these non-working populations are more vulnerable to the effects of pesticides, and may be at increased risk of developing neurocognitive effects and impaired development. While measuring biomarkers or markers of biological effects may provide more accurate estimates of exposure, collecting these data in

990-474: Is substantial evidence of associations between organophosphate insecticide exposures and neurobehavioral alterations. Limited evidence also exists for other negative outcomes from pesticide exposure including neurological, birth defects , and fetal death . The American Academy of Pediatrics recommends limiting exposure of children to pesticides and using safer alternatives: Pesticides are also found in majority of U.S. households with 88 million out of

1056-504: Is to find new compounds or agents with improved properties such as a new mode of action or lower application rate. Another aim is to replace older pesticides which have been banned for reasons of toxicity or environmental harm or have become less effective due to development of resistance . The process starts with testing (screening) against target organisms such as insects , fungi or plants . Inputs are typically random compounds, natural products , compounds designed to disrupt

1122-483: Is widespread in Latin America , as around US$ 3 billion are spent each year in the region. Records indicate an increase in the frequency of pesticide poisonings over the past two decades. The most common incidents of pesticide poisoning is thought to result from exposure to organophosphate and carbamate insecticides. At-home pesticide use, use of unregulated products, and the role of undocumented workers within

1188-598: The UN Environment Programme estimate that 3 million agricultural workers in the developing world experience severe poisoning from pesticides each year, resulting in 18,000 deaths. According to one study, as many as 25 million workers in developing countries may suffer mild pesticide poisoning yearly. Other occupational exposures besides agricultural workers, including pet groomers, groundskeepers , and fumigators , may also put individuals at risk of health effects from pesticides. Pesticide use

1254-624: The United States Environmental Protection Agency (EPA) and the Pest Management Regulatory Agency (PMRA) of Canada. DDT , sprayed on the walls of houses, is an organochlorine that has been used to fight malaria vectors (mosquitos) since the 1940s. The World Health Organization recommend this approach. It and other organochlorine pesticides have been banned in most countries worldwide because of their persistence in

1320-434: The environment or the food chain in order to be approved by the authorities. Persistent pesticides, including DDT , were banned many years ago , an exception being spraying in houses to combat malaria vectors . From biblical times until the 1950s the pesticides used were inorganic compounds and plant extracts . The inorganic compounds were derivatives of copper , arsenic , mercury, sulfur , among others, and

1386-605: The fertility of soil by adding organic matter and nutrients , such as nitrogen , that are utilised by bacteria , fungi and other organisms in the soil . Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web . There are in the 21st century three main classes of manures used in soil management : Most animal manure consists of feces . Common forms of animal manure include farmyard manure (FYM) or farm slurry ( liquid manure ). FYM also contains plant material (often straw), which has been used as bedding for animals and has absorbed

1452-499: The phloem or both. Non-systemic pesticides (contact pesticides) remain on the surface and act through direct contact with the target organism. Pesticides are more effective if they are systemic. Systemicity is a prerequisite for the pesticide to be used as a seed-treatment. Pesticides can be classified as persistent (non-biodegradable) or non-persistent ( biodegradable ). A pesticide must be persistent enough to kill or control its target but must degrade fast enough not to accumulate in

1518-533: The 121.1 million households indicating that they use some form of pesticide in 2012. As of 2007, there were more than 1,055 active ingredients registered as pesticides, which yield over 20,000 pesticide products that are marketed in the United States. Owing to inadequate regulation and safety precautions, 99% of pesticide-related deaths occur in developing countries that account for only 25% of pesticide usage. One study found pesticide self-poisoning

1584-538: The 2000s and less than 40 in the 2010s. Biopesticides are cheaper to develop, since the authorities require less toxicological and environmental study. Since 2000 the rate of new biological product introduction has frequently exceeded that of conventional products. More than 25% of existing chemical pesticides contain one or more chiral centres (stereogenic centres). Newer pesticides with lower application rates tend to have more complex structures, and thus more often contain chiral centres. In cases when most or all of

1650-456: The 2020s the official policy of international organisations, industry, and many governments. With the introduction of high yielding varieties in the 1960s in the green revolution , more pesticides were used. Since the 1980s genetically modified crops were introduced, which resulted in lower amounts of insecticides used on them. Organic agriculture, which uses only non-synthetic pesticides, has grown and in 2020 represents about 1.5 per cent of

1716-619: The Latin pestis (plague) and caedere (kill). The Food and Agriculture Organization (FAO) has defined pesticide as: Pesticides can be classified by target organism (e.g., herbicides , insecticides , fungicides , rodenticides , and pediculicides – see table), Biopesticides according to the EPA include microbial pesticides, biochemical pesticides, and plant-incorporated protectants. Pesticides can be classified into structural classes, with many structural classes developed for each of

1782-745: The Rodale Institute's board of directors along with Whole Foods general counsel Roberta Lang. The Rodale Institute conducts research that seeks to improve the viability, productivity and documented ecological services of organic farming using current agricultural technologies and practices. Focusing on agronomic and some horticultural cropping systems, research trials examine organic and conventional practices, chemical-free weed-management techniques, weed- and disease-resistant crop varieties, compost management and application, soil health , no-till organic planting systems using cover crops and optimal cover-crop uses in organic crop rotations. Part of

1848-660: The Rodale Institute's research has been the ongoing Farming Systems Trial (FST). Begun in 1981, the FST compares two organic farming systems— manure -based and legume -based approaches—to conventional farming methods, defined as methods using Cooperative Extension -prescribed chemical and tillage inputs. FST found that after fields undergo a multi-year transition period to restore biological activity, organic yields are comparable to those of conventional systems. Additionally, organic yields exceed those of conventional systems in years of drought and other stress. Furthermore, organic systems have

1914-703: The USA (457 kt) was the second-largest user. Applications per cropland area in 2021 varied widely, from 10.9 kg/ hectare in Brazil to 0.8 kg/ha in the Russian Federation. The level in Brazil was about twice as high as in Argentina (5.6 kg/ha) and Indonesia (5.3 kg/ha). Insecticide use in the US has declined by more than half since 1980 (0.6%/yr), mostly due to the near phase-out of organophosphates . In corn fields,

1980-595: The Workplace". Better understanding of how pesticides elicit their toxic effects is needed before this method of exposure assessment can be applied to occupational exposure of agricultural workers. Alternative methods to assess exposure include questionnaires to discern from participants whether they are experiencing symptoms associated with pesticide poisoning. Self-reported symptoms may include headaches, dizziness, nausea, joint pain, or respiratory symptoms. Multiple challenges exist in assessing exposure to pesticides in

2046-572: The agricultural industry makes characterizing true pesticide exposure a challenge. It is estimated that 50–80% of pesticide poisoning cases are unreported. Underreporting of pesticide poisoning is especially common in areas where agricultural workers are less likely to seek care from a healthcare facility that may be monitoring or tracking the incidence of acute poisoning. The extent of unintentional pesticide poisoning may be much greater than available data suggest, particularly among developing countries. Globally, agriculture and food production remain one of

2112-410: The benefits of organic agriculture to more people. Starting in 1942, Rodale began publishing his views and practical advice in his startup magazine, Organic Farming and Gardening . In the magazine, he avidly promoted a holistic, whole-systems approach to agriculture. After J.I. Rodale died in 1971, his son Robert Rodale expanded his father's agriculture and health-related pursuits with the purchase of

2178-748: The board with Ardath in 2005. Testimony by Bob Rodale, John Haberern, and farmers and agricultural scientists helped convince the U.S. Congress to fund sustainable agriculture , which was initially called "Low-Input Sustainable Agriculture", in the 1985 Farm Bill . This validation of an agroecological approach to farming led to the formation of the USDA 's Sustainable Agriculture Research and Education (SARE) program in 1990. Federal, state, and local governments, and land-grant universities and other organizations nationally are pursuing sustainable and organic agriculture research and education programs. J.I. Rodale's great-granddaughter Maya Rodale serves as co-chairman of

2244-632: The breakdown of acetylcholine at the neural synapse . Excess acetylcholine can lead to symptoms like muscle cramps or tremors, confusion, dizziness and nausea. Studies show that farm workers in Ethiopia, Kenya, and Zimbabwe have decreased concentrations of plasma acetylcholinesterase, the enzyme responsible for breaking down acetylcholine acting on synapses throughout the nervous system . Other studies in Ethiopia have observed reduced respiratory function among farm workers who spray crops with pesticides. Numerous exposure pathways for farm workers increase

2310-536: The capacity to sequester significant amounts of carbon. Current experiments also pursue improvements in no-tillage and minimum tillage systems with the use of Rodale's "no-till roller/crimper" device created by Jeff Moyer. The device simultaneously rolls and crimps a cover crop, forming a mulch layer into which a cash crop can be planted in the same pass with a special no-till planter. No-till systems with cover crops can contribute to carbon sequestration by adding to and preserving organic matter (57% carbon by weight) in

2376-403: The compound is metabolized and eliminated from the body, and provide insights into the timing of exposure. Markers of biological effect provide an estimation of exposure based on cellular activities related to the mechanism of action. For example, many studies investigating exposure to pesticides often involve the quantification of the acetylcholinesterase enzyme at the neural synapse to determine

2442-746: The cost side of pesticide use there can be costs to the environment and costs to human health. Pesticides safety education and pesticide applicator regulation are designed to protect the public from pesticide misuse , but do not eliminate all misuse. Reducing the use of pesticides and choosing less toxic pesticides may reduce risks placed on society and the environment from pesticide use. Pesticides may affect health negatively. mimicking hormones causing reproductive problems, and also causing cancer. A 2007 systematic review found that "most studies on non-Hodgkin lymphoma and leukemia showed positive associations with pesticide exposure" and thus concluded that cosmetic use of pesticides should be decreased. There

2508-505: The decline was even steeper, due to the switchover to transgenic Bt corn . Pesticides increase agricultural yields and lower costs. One study found that not using pesticides reduced crop yields by about 10%. Another study, conducted in 1999, found that a ban on pesticides in the United States may result in a rise of food prices , loss of jobs, and an increase in world hunger. There are two levels of benefits for pesticide use, primary and secondary. Primary benefits are direct gains from

2574-502: The environment and human toxicity. DDT has become less effective, as resistance was identified in Africa as early as 1955, and by 1972 nineteen species of mosquito worldwide were resistant to DDT. Total pesticides use in agriculture in 2021 was 3.54 million tonnes of active ingredients (Mt), a 4 percent increase with respect to 2020, an 11 percent increase in a decade, and a doubling since 1990. Pesticides use per area of cropland in 2021

2640-409: The exact biological mechanism which the pesticide disrupts. The modes of action are important for resistance management, and are categorized and administered by the insecticide , herbicide , and fungicide resistance action committees. Pesticides may be systemic or non-systemic. A systemic pesticide moves (translocates) inside the plant. Translocation may be upward in the xylem , or downward in

2706-493: The feces and urine . Agricultural manure in liquid form, known as slurry , is produced by more intensive livestock rearing systems where concrete or slats are used instead of straw bedding. Manure from different animals has different qualities and requires different application rates when used as fertilizer. For example horses , cattle , pigs , sheep , chickens , turkeys , rabbits , and guano from seabirds and bats all have different properties. For instance, sheep manure

2772-589: The field is often impractical and many methods are not sensitive enough to detect low-level concentrations. Rapid cholinesterase test kits exist to collect blood samples in the field. Conducting large scale assessments of agricultural workers in remote regions of developing countries makes the implementation of these kits a challenge. The cholinesterase assay is a useful clinical tool to assess individual exposure and acute toxicity. Considerable variability in baseline enzyme activity among individuals makes it difficult to compare field measurements of cholinesterase activity to

2838-476: The future. He wrote that regenerative organic farming can use its own internal resources to improve soil fertility and productivity over time, rather than relying on expensive—and potentially environmentally damaging—outside chemical inputs. Bob Rodale died in a 1990 automobile accident in Moscow while launching a Russian edition of Rodale's New Farm magazine. John Haberern, who had been hired by Robert Rodale as

2904-608: The general population, and many others that are specific to occupational exposures of agricultural workers. Beyond farm workers, estimating exposure to family members and children presents additional challenges, and may occur through "take-home" exposure from pesticide residues collected on clothing or equipment belonging to parent farm workers and inadvertently brought into the home. Children may also be exposed to pesticides prenatally from mothers who are exposed to pesticides during pregnancy. Characterizing children's exposure resulting from drift of airborne and spray application of pesticides

2970-505: The growth of the pesticide industry. During this period, it became increasingly evident that DDT, which had been sprayed widely in the environment to combat the vector, had accumulated in the food chain . It had become a global pollutant, as summarized in the well-known book Silent Spring .Finally, DDT was banned in the 1970s in several countries, and subsequently all persistent pesticides were banned worldwide, an exception being spraying on interior walls for vector control. Resistance to

3036-484: The incorporation of nutrients and organic matter into the soil. Leguminous plants such as clover are often used for this, as they fix nitrogen using Rhizobia bacteria in specialized nodes in the root structure. Other types of plant matter used as manure include the contents of the rumens of slaughtered ruminants , spent grain (left over from brewing beer ) and seaweed . Animal manure, such as chicken manure and cow dung , has been used for centuries as

3102-539: The largest industries. In East Africa, the agricultural industry represents one of the largest sectors of the economy, with nearly 80% of its population relying on agriculture for income. Farmers in these communities rely on pesticide products to maintain high crop yields. Some East Africa governments are shifting to corporate farming , and opportunities for foreign conglomerates to operate commercial farms have led to more accessible research on pesticide use and exposure among workers. In other areas where large proportions of

3168-440: The magnitude of the inhibitory effect of organophosphate and carbamate pesticides. Another method of quantifying exposure involves measuring, at the molecular level, the amount of pesticide interacting with the site of action. These methods are more commonly used for occupational exposures where the mechanism of action is better understood, as described by WHO guidelines published in "Biological Monitoring of Chemical Exposure in

3234-412: The manure due to spillage. For example, chickens are often fed meat and bone meal , an animal product, which can end up becoming mixed with chicken litter. Compost is the decomposed remnants of organic materials. It is usually of plant origin, but often includes some animal dung or bedding. Green manures are crops grown for the express purpose of plowing them in, thus increasing fertility through

3300-412: The method of choice in one third of suicides worldwide, and recommended, among other things, more restrictions on the types of pesticides that are most harmful to humans. A 2014 epidemiological review found associations between autism and exposure to certain pesticides, but noted that the available evidence was insufficient to conclude that the relationship was causal. The World Health Organization and

3366-524: The nation and world enable institute researchers to replicate experiments across different geographical regions and benefit farmers with opportunities to test new approaches to organic production. The institute allies with national and state-level organic certification programs, industry leaders and elected officials to help shape policy. The institute also partners strategically with U.S. and foreign government entities, businesses, and organizations to promote regenerative organic farming opportunities and to expand

3432-416: The optimized compounds must meet several requirements. In addition to being potent (low application rate), they must show low toxicity to non-target organisms, low environmental impact, and viable manufacturing cost. The cost of developing a pesticide in 2022 was estimated to be 350 million US dollars. It has become more difficult to find new pesticides. More than 100 new active ingredients were introduced in

3498-412: The parent compound or its metabolites in various types of media: urine, blood, serum. Biomarkers may include a direct measurement of the compound in the body before it's been biotransformed during metabolism. Other suitable biomarkers may include the metabolites of the parent compound after they've been biotransformed during metabolism. Toxicokinetic data can provide more detailed information on how quickly

3564-1144: The partial bans on neonicotinoids . Revised 2023 guidance by registration authorities describes the bee testing that is required for new insecticides to be approved for commercial use. In addition to their main use in agriculture , pesticides have a number of other applications. Pesticides are used to control organisms that are considered to be harmful, or pernicious to their surroundings. For example, they are used to kill mosquitoes that can transmit potentially deadly diseases like West Nile virus , yellow fever , and malaria . They can also kill bees , wasps or ants that can cause allergic reactions. Insecticides can protect animals from illnesses that can be caused by parasites such as fleas . Pesticides can prevent sickness in humans that could be caused by moldy food or diseased produce. Herbicides can be used to clear roadside weeds, trees, and brush. They can also kill invasive weeds that may cause environmental damage. Herbicides are commonly applied in ponds and lakes to control algae and plants such as water grasses that can interfere with activities like swimming and fishing and cause

3630-554: The pesticidal activity in a new compound is found in one enantiomer (the eutomer ), the registration and use of the compound as this single enantiomer is preferred. This reduces the total application rate and avoids the tedious environmental testing required when registering a racemate. However if a viable enantioselective manufacturing route cannot be found, then the racemate is registered and used. Insecticides with systemic activity against sucking pests, which are safe to pollinators , are sought after, particularly in view of

3696-399: The plant extracts contained pyrethrum , nicotine , and rotenone among others. The less toxic of these are still in use in organic farming . In the 1940s the insecticide DDT , and the herbicide 2,4-D , were introduced. These synthetic organic compounds were widely used and were very profitable. They were followed in the 1950s and 1960s by numerous other synthetic pesticides, which led to

3762-531: The population rely on subsistence, small-scale farming, estimating pesticide use and exposure is more difficult. Pesticides may exhibit toxic effects on humans and other non-target species, the severity of which depends on the frequency and magnitude of exposure. Toxicity also depends on the rate of absorption, distribution within the body, metabolism, and elimination of compounds from the body. Commonly used pesticides like organophosphates and carbamates act by inhibiting acetylcholinesterase activity, which prevents

3828-421: The risk of pesticide poisoning, including dermal absorption walking through fields and applying products, as well as inhalation exposure. There are multiple approaches to measuring a person's exposure to pesticides, each of which provides an estimate of an individual's internal dose. Two broad approaches include measuring biomarkers and markers of biological effect. The former involves taking direct measurement of

3894-1131: The soil, an important component of the institute's goal to link organic agriculture with the campaign to mitigate global warming. Other experiments focus on biological pest controls, the use of mychorrhizal fungi – hosted by root systems in a symbiotic relationship – to amplify crops' abilities to uptake nutrients, and time-sensitive planting to avoid insect cycles and maximize the use of growing degree day (s). Rodale Institute has 8 locations, including four Regional Resource Centers, satellite campuses in which research into regenerative organic agriculture can be conducted at scale in different climates, soil types, and communities. Pesticide Pesticides are substances that are used to control pests . They include herbicides , insecticides , nematicides , fungicides , and many others (see table). The most common of these are herbicides, which account for approximately 50% of all pesticide use globally. Most pesticides are used as plant protection products (also known as crop protection products), which in general protect plants from weeds , fungi, or insects . In general,

3960-475: The target organisms listed in the table. A structural class is usually associated with a single mode of action , whereas a mode of action may encompass more than one structural class. The pesticidal chemical ( active ingredient ) is mixed ( formulated ) with other components to form the product that is sold, and which is applied in various ways. Pesticides in gas form are fumigants . Pesticides can be classified based upon their mode of action , which indicates

4026-442: The use of pesticides and secondary benefits are effects that are more long-term. Controlling pests and plant disease vectors Controlling human/livestock disease vectors and nuisance organisms Controlling organisms that harm other human activities and structures In 2018 world pesticide sales were estimated to be $ 65 billion, of which 88% was used for agriculture.

4092-415: The water to look or smell unpleasant. Uncontrolled pests such as termites and mold can damage structures such as houses. Pesticides are used in grocery stores and food storage facilities to manage rodents and insects that infest food such as grain. Pesticides are used on lawns and golf courses , partly for cosmetic reasons. Integrated pest management , the use of multiple approaches to control pests,

4158-412: The world. Any quantity of animal manure may be a source of pathogens or food spoilage organisms which may be carried by flies , rodents or a range of other vector organisms and cause disease or put food safety at risk. In intensive agricultural land use, animal manure is often not used as targeted as mineral fertilizers, and thus, the nitrogen utilization efficiency is poor. Animal manure can become

4224-415: The world’s total agricultural land. Pesticides have become more effective. Application rates fell from 1,000–2,500 grams of active ingredient per hectare (g/ha) in the 1950s to 40–100 g/ha in the 2000s. Despite this, amounts used have increased. In high income countries over 20 years between the 1990s and 2010s amounts used increased 20%, while in the low income countries amounts increased 1623%. The aim

4290-478: Was 2.26 kg per hectare (kg/ha), an increase of 4 percent with respect to 2020; use per value of agricultural production was 0.86 kg per thousand international dollar (kg/1000 I$ ) (+2%); and use per person was 0.45 kg per capita (kg/cap) (+3%). Between 1990 and 2021, these indicators increased by 85 percent, 3 percent, and 33 percent, respectively. Brazil was the world's largest user of pesticides in 2021, with 720 kt of pesticides applications for agricultural use, while

4356-450: Was estimated that for every dollar ($ 1) that is spent on pesticides for crops results in up to four dollars ($ 4) in crops which would otherwise be lost to insects, fungi and weeds. In general, farmers benefit from having an increase in crop yield and from being able to grow a variety of crops throughout the year. Consumers of agricultural products also benefit from being able to afford the vast quantities of produce available year-round. On
