(Beyond Pesticides, January 16, 2013) Children living near chemical-intensive or conventional plantations in Costa Rica are exposed to twice as much of the insecticide chlorpyrifos compared to children living near organic plantations, a study reports. More than half the children, mostly from indigenous tribes- Ngäbe and Bribri – have a  higher daily exposures than allowed under U.S. federal standards. Chlorpyrifos is linked to neurological effects, especially in children, and is still permitted for use on crops. The study,  Indigenous children living nearby plantations with chlorpyrifos-treated bags have elevated 3,5,6-trichloro-2-pyridinol (TCPy) urinary concentrations, was lead by Berna van Wendel de Joode, PhD  (Central American Institute for Studies on Toxic Substances (IRET), Universidad Nacional, Heredia, Costa Rica). It was conducted in Costa Rica’s banana and plantain plantations in the Talamanca region, and  targeted villages situated nearby to the plantations where blue bags treated with chlorpyrifos are routinely used to protect banana and plantain crops from pests. Two villages under study are near plantations that use chlorpyrifos-treated bags, while the organic village is near several plantations  that use little or no insecticide. For 140 children, aged 6 — 9, mostly indigenous Ngäbe and Bribri, parent-interviews and urine samples were obtained. Chlorpyrifos’ environmental levels […]

(Beyond Pesticides, November 28, 2012) Earlier this year the maker of the fumigant methyl iodide indicated it would stop producing the toxic chemical. Now, the U.S. Environmental Protection Agency (EPA) and the registrant, Arysta LifeScience North America, LLC have entered into a Memorandum of Agreement to formally terminate all agricultural use of methyl iodide in the U.S. by the end of 2012 and ultimately remove all methyl iodide products from the U.S. market. EPA is opening a 30-day comment period for Arysta’s request for voluntary cancellation of all of the company’s methyl iodide product registrations, as stipulated in the agreement. Methyl iodide, or iodomethane, has been registered since 2007 for use as a pre-plant soil fumigant to control pests in soil where fruits, vegetables, ornamental plants, and turf are to be grown. In March 2012, Arysta, the sole registrant, announced its plans to immediately suspend all sales of its methyl iodide MIDAS ® products in the U.S. Under the recently signed agreement and the voluntary cancellation request, all of Arysta’s existing methyl iodide end-use product registrations will be cancelled and use of existing stocks in the U.S. will be prohibited effective December 31, 2012. Further distribution and sale of methyl […]

(Beyond Pesticides, November 1, 2012) Conservation groups and fisherman have filed lawsuits against U.S. Environmental Protection Agency (EPA) demanding that pesticide restrictions be implemented around salmon streams. Regulatory buffers surrounding streams and watersheds have not been fully implemented by EPA, though it is required to by law. The National Marine Fisheries Service (NMFS), which promotes sustainable fisheries, recovery of protected species, and the health of coastal marine habitats, commented that common pesticides should not be sprayed within 500 to 1000 feet of waterways. Its comments focused on the impacts of chlorpyrifos, diazinon and malathion, which jeopardize the health of federally protected salmon species. Despite this and other evidence that supports the need for buffer zones, EPA has withheld action until the 4th U.S. Circuit Court of Appeals resolves the case. EPA is mandated by law to protect dwindling species like salmon under the Endangered Species Act. Salmon, in particular, are a good indicator of how well we are taking care of both the marine and terrestrial ecosystems, because they live in streams, lakes, rivers, estuaries, and open ocean. They are also extremely sensitive to changes in water quality and upstream changes to the river flow, turbidity, and temperature. It goes […]

(Beyond Pesticides, October 16, 2012) The Oregon Department of Agriculture (ODA) is looking to revamp the way it enforces the 1993 Agricultural Water Quality Management Act in order to decrease the amount of pesticides that end up in the state’s waterways from agricultural nonpoint source pollution. The new plan, which was unveiled last December, will work by taking a firmer approach than the current plan, which on sporadic complaints for enforcement and cooperative action by residents through soil and water conservation districts. While a new plan could benefit the health of Oregon residents and its waterways, it is in danger because politicians and some farmers believe it will be overly burdensome and increase costs. Oregon is no stranger to problems with pesticide contamination of its water. The state of Oregon has a complex and diverse agricultural economy which ranges from forestry products to seed crops. Oregon also has thousands of miles of waterways. Roughly 15,000 miles of these waterways are listed as impaired, and nearly half of the 11,000-plus miles of waterways in Willamette River basin need more streamside plants, according to a 2009 state report. These plants help reduce the amount of run off by reducing the amount of […]

(Beyond Pesticides, October 11, 2012) A new report highlights the growing body of research that links pesticides to the rampant rise of learning disabilities, childhood cancer and asthma in the United States, and calls for swift policy change to protect future generations. In particular, the report points out that children are more sick today than they were a generation ago, confronting serious health challenges from pesticides and other chemical exposures that their parents and grandparents were unlikely to face. This report underscores the importance of changing the individual chemical assessment approach to regulating pesticides, and integrating a systems approach that incorporates organic principles that strive to eliminate unnecessary pesticide use. The report entitled, A Generation in Jeopardy: How pesticides are undermining our children’s health and intelligence was released by Pesticide Action Network North America (PAN). It draws from academic and government research, focusing on studies published within the past five years, to chronicle the emerging threat of —with over 1 billion pounds applied on farms and homes annually— to children’s health. Children and other sensitive sub-populations are exposed to a “toxic soup” of chemicals whose health impacts are not properly understood and clouded in uncertainties which are not captured in […]

(Beyond Pesticides, July 25, 2012) A Texas border study has found that air samples in the homes of pregnant Hispanic women contain multiple household pesticides that could harm fetuses and young children. The first study of its kind conducted by the School of Medicine at The University of Texas Health Science Center San Antonio, finds traces of both household and agricultural pesticides that have been linked to disorders such as autism and attention deficit hyperactivity disorder. The researchers sampled air in 25 households, finding at least five pesticides in 60 percent of the dwellings. Nine other pesticides were identified in less than one-third of the homes. All the women were in the third trimester of pregnancy, when the fetal brain undergoes a growth spurt. Numerous studies have reported birth defects and developmental problems when fetuses and infants are exposed to pesticides, especially exposures that adversely affect mental and motor development during infancy and childhood. This new report is in the summer issue of the Texas Public Health Journal sent to members this week. The study found 92 percent of air samples contained o-phenylphenol, which is used as a fungicide, germicide and household disinfectant, while 80 percent of samples contained chlorpyrifos, […]

(Beyond Pesticides, July 23, 2012) The U.S. Environmental Protection Agency’s (EPA) announcement last week of new agricultural risk mitigation measures for the neurotoxic insecticide chlorpyrifos continues to ignore farmworker health and that of their families, as well as the viability of organic farming systems in providing not only safer food, but safer working environments for farmworkers. The new measures, while a step in the right direction to protect vulnerable populations, do not go far enough to address the unreasonable risks associated with the chemical’s widespread continued use. The national pesticide law, the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), requires protection against “unreasonable adverse effects to man or the environment.” In its latest decision, EPA seeks to reduce exposure to “acceptable” risk levels. In this case, the agency is seeking to reduce exposure of bystanders to spray applications. The measures include reductions in aerial application rates of the insecticide and the establishment of mandatory buffers around sensitive sites where bystanders including children are known to suffer exposure. The new mitigation practices include reducing the maximum amount of chlorpyrifos that can be applied per acre using spray applications from 6 pounds/acre to 2 pounds/acre. The new measures also include no-spray buffer […]

(Beyond Pesticides, July 5, 2012) After a 2006 cancellation of uses due to unreasonable risks to farmworker health and the environment, and a 6-year phase out scheduled to conclude this September, the U.S. Environmental Protection Agency (EPA) is conducting a risk-benefit analysis to make a determination whether to keep in place or amend the cancellation order for the organophosphate azinphos-methyl (AZM), citing new information on the economic costs of using alternatives. In 2001, EPA found that insecticides azinphos-methyl (AZM) posed unacceptable risks to farmworkers and announced that 28 crop uses were being canceled, seven crop uses were to be phased-out over four years, and eight crop uses were to be allowed to continue under a “time-limited” registration for another four years. Farmworker advocates challenged that decision in federal court citing that EPA failed to take into account the costs of poisoning workers, exposing children, and polluting rivers and streams. A settlement agreement effectively stayed the legal challenge pending EPA’s reconsideration of the “time limited” uses of AZM. In November 2006, EPA decided that AZM poses unreasonable adverse effects and issued a final decision to cancel AZM, but allowed continued use on some fruit crops (apples, cherries, pears) for six more […]

(Beyond Pesticides, March 23, 2012) In a victory for environmentalists and farmworkers, manufacturers of the controversial and highly toxic fumigant methyl iodide announced it will cease selling its products containing the chemical in the U.S. market earlier this week. Representatives from the Tokyo-based company, Arysta LifeScience say that the decision was made as a part of an internal review and based on its economic viability in the U.S.; however, the company will still continue to sell methyl iodide products in other countries. “Today I’m really happy. It feels like someone finally listened to us about something really important.” Gabriela Rincon, told the Los Angeles Times. Ms. Rincon is the daughter of farmworkers who pick strawberries in the Salinas area in California. Methyl iodide causes late term miscarriages, contaminates groundwater and is so reliably carcinogenic that it’s used to create cancer cells in laboratories. It is on California’s official list of known carcinogenic chemicals and has been linked to serious risks in reproductive and neurological health. The pesticide poses the most direct risks to farmworkers and those in the surrounding communities because of the volume that would need to be applied to fields and its tendency to drift off site through […]

Beyond Pesticides, February 21, 2012) Last week, the Monterey County Board of Supervisors urged California Governor Jerry Brown to reconsider the state’s approval of the carcinogenic fumigant methyl iodide. Monterey County, one of the largest agricultural counties in California, joins Santa Cruz County in mounting pressure to re-examine the controversial decision to approve the toxic chemical as a replacement to the ozone-depleting methyl bromide. This news comes at the heels of the announcement earlier this month that Gov. Brown appointed Brian Leahy, a former organic farmer and the former assistant director at the California Department of Conservation, to head the state Department of Pesticide Regulation (DPR). According to The Californian, agricultural interests present asked County Supervisors to take no action. However, with dozens of local farm workers in attendance pleading their case, the board passed the resolution on a 4-1 recommending that Gov. Brown take another look at the fumigant. Methyl iodide is known to cause miscarriages, thyroid dysfunction, and cancer, and is applied to crops like strawberries and peppers. It was approved by California state pesticide regulators in December as an alternative to methyl bromide, an ozone-depleting chemical being phased out under international treaty. In 2007, EPA fast-tracked the […]

(Beyond Pesticides, November 2, 2011) On Monday, a federal judge rejected a lawsuit brought by Dow AgroSciences challenging pesticide application restrictions to protect salmon and upheld the measures recommended by the National Marine Fisheries Service (NMFS) to protect endangered salmon and steelhead from three highly toxic pesticides: chlorpyrifos, diazinon, and malathion. The restrictions, recommended by NMFS’s Biological Opinion in 2008, ban the ground spraying of the three commonly used organophosphate agricultural insecticides within 500 feet of any salmon-bearing waterway, and aerial spraying within 1,000 feet. NMFS has issued four Biological Opinions, the latest on June 2011, which call for several limitations on aerial spraying and ground application of the pesticides near salmon waters, as well as buffer zones around salmon waters and ditches that drain to salmon habitat, among others. EPA was court ordered to consult with NMFS to identify measures needed to protect salmon and steelhead from the pesticides as a result of a 2002 and 2007 lawsuit. Pesticide manufacturers have been willfully ignoring and challenging NMFS’s findings. Dow AgroSciences alleged that NMFS used bad data and modeling and that the proposed buffers are far too large. Earthjustice, representing Northwest Center for Alternatives to Pesticides (NCAP), Pacific Coast Federation […]

(Beyond Pesticides, September 7, 2011) California’s approval of the dangerous and controversial agricultural chemical, methyl iodide, suffered serious questions with the release of new documents showing the fumigant’s registration process was flawed. The documents, which were made public as part of a lawsuit challenging the state’s approval of the chemical, show the state’s Department of Pesticide Regulation (DPR) cut and pasted calculations from different risk assessments in order to come up with a less stringent set of restrictions on the chemical’s use. Earlier this year, several environmental groups sued the State of California for approving the agricultural use of methyl iodide. Methyl iodide is known to cause miscarriages, thyroid dysfunction, and cancer, and is applied to crops like strawberries and peppers. It was approved by California state pesticide regulators in December as an alternative to methyl bromide, an ozone-depleting chemical being phased out under international treaty. Environmental advocacy groups and other opponents of methyl iodide use in the state have released documents detailing dissension in the ranks of DPR over the risk assessment of methyl iodide and its subsequent approval. Earthjustice, a nonprofit environmental law group, sued DPR in an attempt to reverse the state’s approval of the chemical. The […]

(Beyond Pesticides, June 22, 2011) Exposure to two herbicides, atrazine and 2,4-D, commonly used in lawn care and forest management will be studied by Oregon health officials after they were found in the urine of residents of the Triangle Lake area of the Coast Range west of Eugene, Oregon. The State Department of Agriculture is directing health officials who are part of the state’s Pesticide Analytical Response Center to take the lead in studying the matter. Triangle Lake area residents and a group of activists called the Pitchfork Rebellion have been complaining for more than seven years about the possibility that herbicides being aerially sprayed on nearby private forests may be drifting onto their land. The group in the past has asked the state to investigate their concerns, staging rallies and protests, and attending meetings of government agencies, including the pesticide response board and the Oregon Board of Forestry. At an April 2011 meeting of the forestry board, when the group presented proof of chemical exposure, the state agreed to take a closer look. The board regulates logging and related practices on private timberlands in Oregon. At that meeting, Dana Barr, PhD, a research professor at Emory University’s Environmental and […]

(Beyond Pesticides, March 30, 2011) The Maryland House of Delegates passed the Fertilizer Use Act of 2011 (HB 573) on March 23 to limit ferilizer use on lawns, while a new report published by Environment Maryland Research and Policy Center finds that turf grass management, not agriculture, is the leading cause of fertilizer-based nitrogen runoff that pollutes the Chesapeake Bay. The report recommends an additional 30 percent reduction in nutrient levels in order to achieve a clean, sustainable Bay. The Maryland legislation would set limits on the amount of phosphorus and nitrogen in lawn-fertilizers and prohibit the application of lawn fertilizers within 15 feet of a waterway, when the ground is frozen, or between November 15 and March 1. the Maryland Senate version, SB 487, is now under consideration. Pollution in the Chesapeake Bay – which supports over 3,600 species of plants, fish, and other animals – increases when nutrients wash into its waters from snow and rainfall. And many synthetic lawn fertilizers, including ”˜weed and feed’ products, have an excess of two problematic nutrients, nitrogen and phosphorous. Maryland requires cities and farms to keep a close eye on nutrient runoff in the Chesapeake Bay, but the report, “Urban Fertilizers […]

(Beyond Pesticides, March 18, 2011) As a result of recent court mandated consultations under the Endangered Species Act (ESA) concerning pacific salmon and steel head, the U.S. Environmental Protection Agency (EPA) in a letter to the National Research Council (NRC) is requesting the convening of a committee of independent experts to assist in the review of special scientific and technical issues that have arisen as the agency attempts to stem the impact of pesticides on these endangered species. Citing issues of scientific complexity and high importance, the letter authored by EPA Administrator Lisa Jackson, requests on behalf of the EPA, the Fish and Wildlife Service and the National Marine Fisheries Service (NMFS), a “concerted, closely coordinated effort” to address these issues openly and actively. NRC’s assistance is sought due to the number of complex scientific issues brought to the attention of the agencies as they complete consultations under the ESA concerning the impact of pesticides on endangered salmon and steelhead. Even though calls for EPA to holistically review pesticides have been made by scientists and the environmental community before, EPA is now seeking advice in assessing the effect of pesticides and other Federal Insecticide, Fungicide and Rodenticide Act (FIFRA)-related actions […]

(Beyond Pesticides, December 3, 2010) Ignoring the assessments of top U.S. scientists and its own Scientific Review Committee, the California Department of Pesticide Regulation (DPR) announced its approval on December 1, 2010 for use of methyl iodide, a potent carcinogen and water contaminant, as a fumigant in the state’s strawberry fields, nut orchards, and flower farms. The news comes one day after press events in eight California cities urging DPR to deny its approval, and after Washington State decided to not allow use of the chemical.”¨ Methyl iodide poses great risk to farmworkers and those who live near fields where it will be applied as well as to air and waterways, should it escape into the surrounding environment. It is on California’s official list of known carcinogenic chemicals and has been linked to serious risks in reproductive and neurological health. A coalition of farmworker, farm, public health and environmental groups is calling on the administration of governor-elect Jerry Brown to work with his agency staff to undo this approval, and deny the use of methyl iodide in California. Specifically, the groups call on Brown to: ”¢ Follow the recommendation of John Froines, PhD, Chair of the Scientific Review Committee, to […]

(Beyond Pesticides, December 1, 2010) Several fishing and environmental conservation groups are suing the U.S. Environmental Protection Agency (EPA) for failing to limit the use of six agricultural pesticides to protect salmon. Restrictions on the use of six pesticides in Oregon, Washington and California shown to harm endangered salmon and steelhead, were ordered after a court found that EPA violated the Endangered Species Act (ESA) by failing to restrict the pesticides from entering salmon habitat. However EPA has failed to act to restrict the pesticides. The lawsuit, filed in U.S. District Court in Washington is the fourth lawsuit the plainstiffs -Northwest Coalition for Alternatives to Pesticides, Pacific Coast Federation of Fishermen’s Associations; Institute for Fisheries Resources and Defenders of Wildlife- brought against the EPA to restrict the pesticides diazinon, malathion, chlorpyrifos, carbaryl, carbofuran and methomyl in streams of endangered salmon and steelhead. The plaintiffs seek a judgment declaring that EPA’s failure to implement the organophosphate (OP) and carbamate biological opinions issued by the National Marine Fisheries Service (NMFS) violates the ESA, and a judgment declaring that EPA is taking listed salmonids in violation of the ESA. The lawsuit seeks an order vacating and enjoining EPA’s authorization of the uses of […]

(Beyond Pesticides, October 6, 2010) Organic and genetically modified organism (GMO)-free conventional farmers and food processors need legal certainty that they can continue to produce food free of GMO contamination. This, according to the International Federation of Organic Agriculture Movements (IFOAM)— EU Regional Group, which responded to a presentation by EU Commissioner for Health and Consumer Protection John Dalli on “best practice document” for genetically modified (GM) maize. The best practice document outlines voluntary guidelines for the coexistence of genetically modified crops with conventional and organic farming, but fails to address the economic and social impacts on contaminated non-GMO farms. Commissioner Dalli presented to the Farm Council proposals on GMO cultivation, as well as a new “best practice document” for maize. “Commissioner Dalli is trying to snake his way through crucial GMO policies by attempting to satisfy all conflicting parties with his proposals to the Farm Council this morning. But his approach still fails to solve the main problems,” comments Christopher Stopes, President of the IFOAM EU Group. “Consumers refuse to eat GMOs which is their democratic right.” The best practice document authored by the European Coexistence Bureau, developed in light of a July 2010 recommendation, reflects the possibility for […]

(Beyond Pesticides, September 8, 2010) The U.S. Environmental Protection Agency (EPA) has received a new Biological Opinion from the National Marine Fisheries Service (NMFS) with a finding that the application of products containing any of 12 organophosphate (OP) pesticides are likely to jeopardize federally listed threatened or endangered Pacific salmon and steelhead and their designated critical habitat. The 12 OPs addressed in this Biological Opinion, issued under the Endangered Species Act, are azinphos-methyl, bensulide, dimethoate, disulfoton, ethoprop, fenamiphos, methamidophos, methidathion, methyl parathion, naled, phorate, and phosmet. This opinion concludes that EPA’s registration of pesticides containing bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet are each likely to jeopardize the continued existence of one or more of the 28 endangered and threatened Pacific salmonids and are each likely to destroy or adversely modify designated critical habitat for one or more of the 28 threatened and endangered salmonids. NMFS reached this conclusion because predicted concentrations of these seven pesticides in salmonid habitats, particularly in floodplain habitats, are likely to cause adverse effects to at least one listed Pacific salmonids including significant reductions in growth or survival. EPA’s registration of bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet is also likely to result […]

(Beyond Pesticides, June 7, 2010) With thousands of violations cited, the pest control company and applicator responsible for the deaths of two young children are only fined several tens of thousands of dollars, a mere slap on the hand. The Utah Department of Agriculture and Food’s (UDAF) Division of Plant Industry has finally filed multiple charges of violations against Bugman Pest and Lawn, Inc. of Bountiful, Utah, and employee Cole Nocks associated with the February 5, 2010 application of the pesticide Fumitoxin (active ingredient: aluminum phosphide) at the residence of Nathan and Brenda Toone of Layton, Utah that lead to the death of their two daughters ages 15-months and 4 years. In addition to the Layton incident, investigators discovered additional violations of the Utah Pesticide Control Act by the company and other employees. The UDAF seeks to revoke Mr. Nocks’s applicator license and has issued him a $27,000 fine, while Bugman Pest and Lawn, Inc. is fined $32,000. Under law, the UDAF is only allowed to file civil penalties. Investigators determined that on February 5, 2010 applicator Cole Nocks operated in a faulty, careless or negligent manner by misapplying the highly toxic and restricted use pesticide, Fumitoxin. Mr. Nocks’s improper […]

(Beyond Pesticides, May 19, 2010) EPA has announced plans to place additional limitations on the use of three N-methyl carbamate pesticides — carbaryl, carbofuran and methomyl — to protect endangered and threatened salmon and steelhead in California, Idaho, Oregon and Washington, in compliance with the Endangered Species Act. The decision comes after manufacturers of the chemicals diazinon, malathion and chlorpyrifos refused to adopt the limits voluntarily. The new protections are based on recommendations by the National Marine Fisheries Service (NMFS) in their April 2009 Biological Opinion relative to use of the three pesticides to ensure no likely jeopardy to 28 threatened or endangered Pacific salmon and steelhead species. In a May 14, 2010 letter to NMFS, EPA explains how the Agency plans to achieve protection goals through the methods outlined by NMFS in the Biological Opinion or by alternative methods that EPA’s scientific analyses determined will achieve the same purpose. For example, EPA will require pesticide drift buffers adjacent to salmon and steelhead habitat but will impose different width buffers, some wider and others narrower than those recommended by NMFS, depending on factors that affect how far the pesticide might drift from the application site. In correspondence to the EPA […]

(Beyond Pesticides, May 4, 2010) On April 30, 2010, despite significant cancer and reproductive health risk, especially to farmworkers and people living near agricultural fields, the California Department of Pesticide Regulation (DPR) proposed the use of a new and highly toxic pesticide, methyl iodide, for widespread agricultural use in California. The U.S. Environmental Protection Agency (EPA) registered methyl iodide in 2007 as a replacement for the ozone-depleting pesticide, methyl bromide. Environmental and public health advocates believe that blocking methyl iodide registration in California will prevent its use elsewhere, since the state will account for the vast majority usage and profitability nationwide. Public comments may be sent to [email protected]. If registered, methyl iodide will be used primarily to fumigate and sterilize the California’s strawberry fields, although the pesticide will also be used in nurseries and nut tree production. DPR’s proposal does not require neighbor notification before use of this extremely toxic chemical. As evidenced by California’s thriving organic industry, alternatives to fumigants exist and are in use in California. In a hearing on February 8, 2010, before the California Senate Committee on Food and Agriculture, two panels of California growers and researchers discussed a number of safe and effective alternatives to […]

(Beyond Pesticides, April 8, 2010) The U.S. Environmental Protection Agency (EPA) is requiring new restrictions on aluminum and magnesium phosphide products in an attempt to better protect people, especially children, from dangerous exposures. The new restrictions prohibit all uses of the products around residential areas and increase buffer zones for treatment around non-residential buildings that could be occupied by people or animals from 15 feet to 100 feet. Human exposure to these toxic chemicals, though slightly minimized, would nevertheless continue because of their continued availability for use on athletic fields and playgrounds, around non-residential buildings, and in agricultural production. Phosphide fumigants are known to be highly acutely toxic when ingested or inhaled. Symptoms of mild to moderate acute exposure include nausea, abdominal pain, tightness in chest, excitement, restlessness, agitation and chills. Symptoms of more severe exposure include diarrhea, cyanosis, difficulty breathing, pulmonary edema, respiratory failure, tachycardia (rapid pulse) and hypotension (low blood pressure), dizziness and/or death. Aluminum and magnesium phosphide fumigants are used primarily to control insects in stored grain and other agricultural commodities. They also are used to control burrowing rodents in outdoor agricultural and other non-domestic areas. The fumigants are restricted to use by specially trained pesticide applicators. […]
