Cypermethrin, alpha - Identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information Note : See Working with the Information on this Page section below for important notes about this data. MOA: Sodium channel modulators, Pyrethroids, Pyrethrins, DDT Group: PYR CAS #: 67375308 Shaugnessy Code: 209600 are used in agricultural crops, mainly on Levels at 7 days were < 10 and 10 m g/kg in renal and subcutaneous fat, respectively, and corresponding figures for the cow sacrificed at 14 days were both 20 m g/kg. The kidney extract contained at least nine metabolites with a broad range of polarities, one component (20% of the profile) had similar chromatographic properties to alphacypermethrin. Evidence of lack of interconversion of the cis isomeric forms to the trans forms during metabolism in the target species; and. The results were not corrected for recovery although the recoveries were determined in each study. A minor component (3 % of the profile) had identical chromatographic properties (HPLC) to 14C-3PBA (3-phenoxybenzoic acid). Although cypermethrin, zeta-cypermethrin, and alpha-cypermethrin are separate active ingredients with different end-use products, they are included together in the hazard evaluation for the purpose of human health risk assessment. Preferably apply to eggs. All of the results for the cold residues were not corrected for recoveries. In a poultry study, hens were treated with an alphacypermethrin spray and residues in eggs measured over a 14 day period. Cypermethrin is toxic to the nervous system. Find my closest branch Contact us Over an eight day collection period 50-60% of the dose was excreted in the urine and 30-40% in the faeces. HRC report SLL 279/931913. Cypermethrin typically contains 20-40% alpha-cypermethrin. Insecticide Pesticide Alpha-Cypermethrin 100g/L SC. and Gill, J.P., (1989). *Please select more than one item to compare The above is the search results for Chinese Cypermethrin, click for more recommended manufacturers & suppliers listings such as insecticide, pesticide, agricultural chemicals. Sherren, A.J., (1988b). Cypermethrin Pesticide Fact Sheet. Fastac® CS insecticide. Acts on the central and peripheral nervous system in very low doses. Applied as a pour-on preparation for cattle and sheep, as a dip for sheep, and as a spray for poultry. The reliable end points, appropriate for use in regulatory risk assessment and the proposed maximum residue levels (MRLs), are presented. Alpha-cypermethrin and zeta-cypermethrin are enriched isomers of the pyrethroid insecticide cypermethrin. SAMS 456-1, (1988). Total cypermethrin use in the United States is approximately 1.0 million pounds of active ingredient (a.i.) It is however significantly more expensive than alpha cypermethrin, only registered for use on chrysomelid lavae, and has large no Table 8. Muscle, fat and milk contained mainly a single component (muscle 85 %, fat 91 % and milk 97 % of the extracted residues), which in each case had similar chromatographic properties to alphacypermethrin. Recoveries were between 80 and 105 %. METHODS OF ANALYSIS FOR RESIDUES IN TISSUES, EGGS AND MILK. Determination of Residues of Alphacypermethrin in Milk. View as Grid List. The results are shown in Table 5. The conclusions were reached on the basis of the evaluation of the representative uses of alpha‐cypermethrin as an insecticide on cereals, winter oilseed rape, lettuces, leafy brassica and on cucumber and courgette in permanent glasshouses. WL 85871 (ACYP, FASTAC). Alpha-cypermethrin is a broad-spectrum type II pyrethroid restricted use pesticide that is registered for use on soybeans, corn, vegetables, sugar beets, wheat, alfalfa and other minor crops.
