Dimethoate is nonvolatile, water soluble, and not mobile in soil, where it degrades with a half-life of approximately 2-4 days, based on soil conditions. This work plan has been prepared to fulfill new legislative requirements intended to improve the transparency and predictability of chemical review decisions. What Additional Scientific Information is Being Requested? Dimethoate has moderate acute toxicity in mammals (e.g., the LD50 in mice and rats is 150 and 400 mg/kg bodyweight, respectively) (IPCS, 1989). Precautions for organophosphorus pesticides include the following. These methods consider the unique characteristics of sensitive subpopulations in both humans (for example, children), and organisms in the environment (for example, those most sensitive to environmental contaminants). In- sect/mite biotypes with acquired resistance to Group 1B may eventu- ally dominate the insect/mite population if Group 1B insecticides or acaricides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. The key objective of the Pest Control Products Act is to prevent unacceptable risks to people, and the environment from the use of pest control products. These uses include the following: application to structural sites, paint-on treatments to birch, roses and lilac, as well as, soil drench application to carnations. DO NOT apply to any non-food tree crop or plantation (including Eucalyptus spp.) Dimethoate is used on both agricultural and non-agricultural sites which include feed, food, industrial oil seed and fibre, forestry and ornamental crops. Dimethoate is a broad spectrum organophosphate insecticide and acaricide. Available at URL: https://www.epa.gov/pesticidesexternal icon/reregistration/REDs/dimethoate_red.pdf4/20/13. Pages 34945-7. Biomonitoring studies on levels of dimethoate and omethoate provide physicians and public health officials with reference values so they can determine if people have been exposed to higher levels of these insecticides than the general population. Agricultural uses of dimethoate in Canada include pest control in barley, canola, oats, pastures, rye, wheat, alfalfa, beans, clovers, corn, flax, mushrooms, peas, potatoes, sugar beets, and Cygon is the manufacture name for products like Bonide and Hi-Yield. INSECTICIDE RESISTANCE WARNING For insect resistance management Adama DIMETHOATE 400 INSECTICIDE is a Group 1B insecticide. Certain uses of dimethoate products have value in the food and crop industry, and do not pose unacceptable risks to human health or the environment. EPA Registration No. Dimethoateis used for Insecticide, Disinfectant and other conditions. Stay upwind; keep out of low areas. FAO Plant Production and Protection Paper, 140, 1997.Rome, 1997. Use on alfalfa, wheat, cotton, and corn crops accounts for more than 60% of the total dimethoate use in the U.S. (U.S. EPA, 2006). In animal studies, inhibition of erythrocyte but not plasma cholinesterase appeared to be the most sensitive indicator of dimethoate exposure and toxicity (Sanderson and Edson, 1964; IPCS, 1989). To reach its decisions, the PMRA applies hazard and risk assessment methods, as well as policies that are rigorous and modern. Reseal and return the container to an authorized Helena Chemical Company refilling facility. Re-evaluation Decision RVD2015-04, Dimethoate describes the PMRA’s regulatory process concerning the re-evaluation of dimethoate, as well, summarizes the Agency’s decision, the reasons for it.

Listed dimethoate insecticide manufacturers, suppliers, dealers & exporters are offering best deals for dimethoate insecticide … In neutral to acidic conditions, greater persistence is noted. 2003. Reproductive toxicity was seen at doses that also caused overt maternal toxicity (IPCS, 2003; U.S. EPA, 1995). - Mechanism of Action & Protocol. Among professional pesticide applicators and formulators, dimethoate exposure can occur by skin contact or from inhaling aerosols or dust. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. Toxicity and Warnings. Br J Ind Med 1964;21:52-64. Potential exposure to dimethoate may occur through the diet, when handling and applying the product, or when entering or contacting treated sites. Dimethoate is widely distributed to body tissues and metabolized in the liver to omethoate (most likely via the cytochrome P450 enzyme system), which is then rapidly broken down to several methylated dialkyl phosphate metabolites that are eliminated in urine within 1-2 days (IPCS, 1989; Menzer and Best, 1968). The conclusions were reached on the basis of the evaluation of the representative uses of dimethoate as insecticide on wheat and sugar beet. Data concerning DM-acute genotoxicity are controversial and knowledge on its delayed effect is limited. In Canada, dimethoate is registered to control a wide range of insect pests such as: aphids, beetles, weevils, grasshoppers, flies, leafhoppers, scale insects, thrips, moths and spider mites. Remove and isolate contaminated clothing at … The drinking water modeling estimates and residue estimates for some foods have been revised since PRVD2011-12 in consideration of new data submitted during the consultation period. Also a Metabolite of Dimethoate. Based on Canadian pesticide labels, dimethoate is the only insecticide currently registered in Canada to control insect pests of Douglas fir (seed tree), Sitka spruce (seed tree) and spruce (seed tree and woodland use). Residential and non-agricultural uses were cancelled in 2000.

To comply with this decision, new and revised risk mitigation measures should be implemented as soon as possible but no later than 30 December 2017. For the control of certain insects including aphids, thrips, jassids, lucerne flea, redlegged earthmite, Queensland fruit fly, leaf hoppers and wingless grasshoper as specified in the Directions for Use table. After a thorough re-evaluation of the insecticide dimethoate, Health Canada’s Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is granting continued registration for the sale and use of dimethoate products in Canada. Where no specific MRL has been established, a default MRL of 0.1 ppm applies, which means that pesticide residues in a food commodity must not exceed 0.1 ppm. “Pick Your Own (PYO)” facilities are commercial farming operations that allow public access for harvesting in large-scale fields or orchards treated with commercially labelled dimethoate products. Health or environmental risk is considered acceptable if there is reasonable certainty that no harm to human health, future generations or the environment will result from use or exposure to the product under its conditions, or proposed conditions of registration. Additional information about external exposures (i.e., environmental levels) and health effects is available from the U.S. EPA at: https://www.epa.gov/pesticidesexternal icon. by air. Many of the bees from the Nova Scotia and Saskatchewan sites contained dimethoate residues, as determined by laboratory analysis. Estimates of exposure that aggregate the dermal exposure incurred during harvest and the dietary exposure from consuming fresh fruit reach the target Margin of Exposure (MOE) for orchard and berry crops, and are therefore, not of concern. Canadian MRLs for dimethoate on apples, cabbage, and spinach will be revoked as the use on these commodities has been discontinued by the registrant in both Canada and the United States. Although never registered for use in the U.S., omethoate has been registered in other countries. CAS No. Proposed rule. General population exposure to dimethoate or omethoate can occur by eating foods treated with dimethoate or by drinking water. 1993;31(3):177-82.

Features: A systemic insecticide/miticide labeled for a variety of pests affecting fruits, vegetables, nuts, citrus, field, and seed crops. When the proposed mitigation measures such as lengthened restricted-entry intervals (REIs) are considered, occupational postapplication risk estimates meet the target MOE, and are not of concern. Sanderson DM, Edson EF. Estimated intakes of dimethoate and omethoate from these sources have not exceeded the U.S. EPA levels of concern (U.S. EPA, 2006). Neither dimethoate nor omethoate bioaccumulate, but both are highly toxic to honey bees, birds, and freshwater invertebrates (U.S. EPA, 2006). Residential and non-agricultural uses were cancelled in 2000. Get dimethoate insecticide at best price with product specifications. The U.S. EPA classified dimethoate as a possible human carcinogen (U.S. EPA, 1995). Concerns are identified. As a result, dietary exposure from food and drinking water were not of concern to the PMRA. 1.3.
