For edible tissues fat is the first choice for a target tissue, the type of fat may not be too important. . The maximum value was 5 m g/l on the 2nd and 4th day after treating with the highest dose. Cypermethrin is a pyrethroid insecticide that mainly affects an insect’s central nervous system, used against a number of insect pests such as aphids, weevils, caterpillars, yellow cereal fly, flea beetles, blossom beetles, pod midge and moth pests on wheat, barley, oats, rye, triticale, peas and beans, brassicas, oilseed rape, sugar beets, fodder beet and mangels, potatoes, apples and pears. It is a racemic mixture of two isomers of Cypermethrin. The studies carried out by the sponsor using the recommended preparations in cattle, sheep and poultry are summarised in Table 2. SAMS 456-1, (1988). Table 2. - There are analytical methods available, however, evidence of validation is needed. TLGR 0131.77. 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 extract was evaporated to dryness, the residue dissolved in hexane and the solution was passed through an Extrelut extraction column. The liver extract contained at least eight metabolites with a broad range of polarities, one component (16 % of the profile) had similar chromatographic properties to alphacypermethrin. The values are probably not corrected for recovery. Sherren, A.J., (1988a).

Residues of Alphacypermethrin in Milk Following Topical Treatment of Cows with "Renegade" Pour-on in the UK. The lower limits of determination for the two methods were 1 m g/l and 2 m g/l for radio counting and GC respectively. Metabolism and elimination of 14C-aryl-labelled cis and trans isomers in rats. Fastac® CS insecticide. Alpha-Cypermethrin contains more than 90% of the insecticidally most active enantiomer pair of the four cis isomers of cypermethrin as, CC1(C(C1C(=O)OC(C#N)C2=CC(=CC=C2)OC3=CC=CC=C3)C=C(Cl)Cl)C, CC1([C@@H]([C@@H]1C(=O)O[C@@H](C#N)C2=CC(=CC=C2)OC3=CC=CC=C3)C=C(Cl)Cl)C, International Chemical Identifier key (InChIKey), International Chemical Identifier (InChI), InChI=1S/C22H19Cl2NO3/c1-22(2)17(12-19(23)24)20(22)21(26)28-18(13-25)14-7-6-10-16(11-14)27-15-8-4-3-5-9-15/h3-12,17-18,20H,1-2H3/t17-,18?,20-/m0/s1. Alphacypermethrin is a highly active broad spectrum insecticide, effective by contact and ingestion against target pests. A further 23 % of the total administered radioactivity was excreted via urine, whereas secretion in milk accounted for < 1 %. Highest levels of radioactivity in fractions of whole milk were detected in cream (1100 m g equivalents/kg) and represented 93 % of the radioactivity in whole milk. Genfarm Alpha Cypermethrin 250SC Insecticide For the control of certain insect pests, including redlegged earth mite on certain field crops and pastures and certain Insect pests on fruit and vegetable crops as indicated in the Directions for Use table. Add to Cart | Add to Compare The WHO Recommended Classification of Pesticides by Hazard identifies alpha-cypermethrin (technical grade) as Class II: moderately hazardous; Main Use: insecticide. The concentrations of radioactivity detected in whole milk after oral dosing collected in the afternoon (34-199 m g equivalents/kg) were higher than in the larger morning samples (14-85 m g equivalents/kg) due to the difference in the sample size. *The population was created solely by selection and/or genetic manipulation. Search results for ALPHA - CYPERMETHRIN at Sigma-Aldrich. Starting at: $52.25 ... PT Fendona Pressurized Insecticide. The Committee noted that alpha-cypermethrin comprises the two most toxicologically active isomers of cypermethrin. Cypermethrin Pesticide Fact Sheet. HRC report SLL 279/931913. It represents the majority of the residue in muscle, milk and fat. In a further study (White, 1987) sheep were treated with a pour-on application at either 0.01 g/kg BW or twice this dose (see Table 2). These figures are not significantly different from the radio counting estimates. Results suggest that this combination could be a potential insecticide resistance management tool for preventing malaria transmission in areas compromise … 8. Table 7. • Cypermethrin Fact Sheet - National Pesticide Information Center 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. In rats 50-60% of a radiolabeled dose was excreted in the urine and 30-40% in the faeces over an eight-day collection period. The majority of the radioactivity was excreted within 48 hours followed by a persistent elimination over the remaining six days. Summary of Residues Trial in Hens and Eggs - Sogeval 1992. 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. An estimate of the residue intake is tabulated as follows: The above MRLs accommodate the ADI and the recommended use of this compound as a veterinary drug. Francis, W.P. Residues of alphacypermethrin (m g/kg) in sheep fat 7 days after treatment with pour-on applications of alphacypermethrin. The cypermethrins have been evaluated for a variety of toxic effects in experimental toxicity studies. Applied as a pour-on preparation for cattle and sheep, as a dip for sheep, and as a spray for poultry. A further 23% of the total administered radioactivity was excreted via urine, whereas secretion in milk accounted for < 1 %. In the milk samples following the pour-on application, total radioactivity mean levels rose to 7 m g/l by day 2 with the range < 1-12 m g/l for the individual animals. SAMS 461-1, (1988). Company: Apparent Pty Ltd Address: Suite G.08, 762 Toorak Road, Glen Iris, Vic. The radiodepletion study submitted for cattle should be reassessed to determine the depletion of the total residues and the parent drug; 3. It is a non-systemic contact and residual insecticide with two to three times greater activity than regular cypermethrin. Recoveries were between 80 and 105 %. These figures are not significantly different from the radio counting estimates. Cameron, D.A., Redgrave, V.A., MacDonald, I.A. A study was carried out of the residues in eggs after a spray application of alphacypermethrin to hens (see Table 2 and Sogeval, 1992). Based on the available data, the only possible option for a marker substance is the parent compound, alphacypermethrin. Corresponding figures for cow 2 were both 20 m g/kg.

United States Environmental Protection Agency. The percentages proposed for the estimation in individual tissues of total residues from the parent drug are; muscle, 30; liver, 10; kidney, 5; fat, 60; milk, 80; eggs, 30; - There is adequate residue information from the non-radiolabelled studies using the recommended formulations; and. Further clean up was obtained by using a Cyano Bond Elut cartridge. A normal hexane/acetonitrile partition was used for all liver and kidney extracts. Alpha-cypermethrin is a widely used pyrethroid insecticide that is approved for use in the EU. Thus the highest level observed in this study was about 30 m g/kg body fat. Alpha-cypermethrin is Used for the control of a wide range of chewing and sucking insects (particularly Lepidotera, Coleoptera, and Hemiptera) in fruit (including citrus), vegetables, vines, cereals, maize, beet, oilseed rape, potatoes, cotton, rice, soya beans, forestry, and other crops. *Please select more than one item to compare Residues of Alphacypermethrin in Cattle Tissues Following Topical Treatment of Calves with "Renegade" Pour-on in the UK. The methods were GC with electron capture detection followed by confirmation with GC-MS. However, it is considered to be a serious water pollutant. Obviously milk or milk fat and the yolk of eggs are suitable for monitoring milk and eggs. The results for the eggs are shown in Table 8. In a poultry study, hens were treated with an alphacypermethrin spray and residues in eggs measured over a 14 day period. Levels fell to just on the limit of determination of 1 m g/l by day 7. 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. 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.

Suitable methods for the specific analysis of alphacypermethrin in milk and the edible tissues were submitted. Residues (m g/kg) of alphacypermethrin in edible tissues of calves after application of a pour-on preparation - dose 0.15 g. The values are the ranges for five calves with the means in brackets. Thorough coverage is essential to ensure adequate control. C.A.S Number: 67375-30-80 (correct stereochemistry), OTHER INFORMATION ON IDENTITIES AND PROPERTIES, Appearance: White-to-cream crystalline solid, Melting range: 81.4-84.0°C (pure material), Vapour pressure: 3.4 x 10-7 Pascals at 25 °C (pure material), Octanol-Water partition coefficient: p = 3.16 x 105, Refractive index: 0.19 x C + 1.344 (C = concentration in kg/l up to 0.25, only in acetonitrile), True density: 1330 kg/m3 (typical for pure material), Alphacypermethrin was determined to be miscible with acetone and dichloromethane at room temperature. The results were not corrected for recovery although the recoveries were determined in each study. Residues of alphacypermethrin were measured by GC-ECD with LOQs of 10-30 m g/kg in tissues and 1-2 m g/kg in milk. Total cypermethrin use in the United States is approximately 1.0 million pounds of active ingredient (a.i.) Radiolabeled depletion studies in dairy cattle using 14C-Alphacypermethrin pour-on applications. However the total residues, using topical application, were below the LOQ in liver and kidney and therefore the sensitivity of the analytical methods could be considered in setting an MRL for these tissues. Ranges for the individual animals by the two methods, respectively, were < 1-12 m g/l and < 2-9 m g/l. The results are shown in Table 7. Residues as alphacypermethrin were measured in cattle, sheep and poultry after the topical application of unlabeled alphacypermethrin. Crawford, M.J. and Hutson, D.H., (1977). The kidney extract contained at least nine metabolites with a broad range of polarities, one component (20% of the residues) had similar chromatographic properties to alphacypermethrin. and Richardson, K.A., (1994). At the end of the 8 days study period approximately 58 % of the total administered dose was recovered. BASF Ag Products ALPHA-CYPERMETHRIN 7969-364. The residues in the yolks at sacrifice were < 5, < 5, 23, 19 and 25 m g/kg. In recommending MRLs the Committee took account of the following factors: - The marker residue is parent drug, alphacypermethrin; - Fat, milk and eggs are target tissues but muscle, liver and kidney should be considered; - The metabolism of the two isomers forming alphacypermethrin is similar to that of the other six isomers in cypermethrin; - The metabolism and radiodepletion studies are not adequate and, therefore, a very conservative estimate of the marker compound as a percentage of total residues in all food species is proposed. Once receive your question, the supplier will answer you as soon as possible. Sodium channel modulator. Thus there is really no indication of the ratio of alphacypermethrin to total residues in these tissues, nor in skin. Set Descending Direction. By acting on the nervous system of insects, the active ingredient in Fastac CS insecticide, alpha-cypermethrin, sustains stimulation of the nerve impulses which leads to overstimulation, exhaustion and death of the insect. The perirenal fat residues were 60-150 m g/kg after the first two weeks post-treatment, but then declined to about 10-20 m g/kg by day 28. The liver extract contained at least eight metabolites with a broad range of polarities, one component (16 % of the residues) had similar chromatographic properties to alphacypermethrin. $27.50 As low as: $19.50 . specifications for alpha-cypermethrin alpha-cypermethrin information 6 alpha-cypermethrin long-lasting (incorporated into filaments) insecticidal net (october 2014) 7 part two evaluations of alpha-cypermethrin 2014.1 fao/who evaluation report on alpha-cypermethrin long-lasting (incorporated into filaments) insecticidal net 12 annex 1: references 13 The metabolic fate of WL 43467 (cypermethrin). It is widely used in agricultural crops, forestry as well as in public and animal health. Fendona CS Controlled Release Insecticide. Two radiolabeled depletion studies in cattle (Redgrave et al., 1992; Cameron et al., 1993) were carried out, one with oral dosing and one using the pour-on application at the recommended dose (Morrison and Richardson, 1994). This was different from the trans isomers where the excretion was virtually complete within 72 hours (Crawford and Hutson, 1977). Residues of Alphacypermethrin (m g/kg) in eggs and yolks after application of a spray of Alphacypermethrin. Liver and kidney contained a range of components. In one study with the pour-on treatment, residues in fat were not detectable within 7 days of dosing but in sheep which were dipped the residues were 40 m g/kg in fat at 7 and 14 days after dosing. Residues of alphacypermethrin (m g/kg) in sheep after treatment with either a pour-on application or a dip formulation of alphacypermethrin. 19 m g/kg). Find my closest branch Contact us Thus there is limited information on the ratio of alphacypermethrin to total residues in these tissues or in skin. MOA: Sodium channel modulators, Pyrethroids, Pyrethrins, DDT Group: PYR CAS #: 67375308 Shaugnessy Code: 209600 The residues in bovine milk were measured on a total daily milk sample collected from cows treated with 3 different doses of a pour-on preparation (Sherren, 1988a). Acts on the central and peripheral nervous system in very low doses. It represents the majority of the residue in muscle, milk and fat. 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. Cypermethrin is an insecticide used both in agricultural and non-agricultural settings. No alphacypermethrin was found in the albumen but residues persisted in the yolk for the 14 day study period. High residues were found for at least two weeks in the skin after both treatments. 4. The total residues (measured as radioactivity) in the edible tissues after the pour-on application were mostly below the LOQ (Redgrave et al., 1992). Alphacypermethrin: Concentrations of Residues in Bovine Tissues. After the application of the pour-on preparation no residues were detectable in the muscle and liver of young cattle and were < 30 m g/kg in kidney over the 14 day post dosing period. Sheep were treated with either a pour-on application or a dip formulation of alphacypermethrin (see study reference 4 in Table 2) and the residues in fat, skin and wool, measured in single sheep at 3, 7 and 14 days post-treatment. The milk samples following the pour-on application were analysed either for total radioactivity or by GC for alphacypermethrin itself [Note: The information on the measurement of cold alphacypermethrin is not given in the reference but only in the expert report]. Alpha cypermethrin is a pyrethroid insecticide consisting essentially of two of the four cis isomers comprising cypermethrin. Alphacypermethrin comprises the (D) and (G) isomers. Table 1. IDENTIFICATION: Alpha-cypermethrin is a highly active pyrethroid insecticide, effective against a wide range of pests encountered in agriculture and animal husbandry. The recovery in fat is 80 to 115%, in muscle 85 to 100%, kidney 85 to 95% and liver 80 to 95%. Germany for the pesticide active substance cypermethrin are reported. In the studies on Cypermethrin (see the monograph) there was evidence of bound residues particularly in liver and kidney, but these usually amounted to < 20% in the liver and < 10% in other tissues. Levels determined by radio counting fell to just on the limit of determination of 1 m g/l by day 7 (Redgrave et al., 1992). Residue studies using unlabeled alphacypermethrin. 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. Alpha-cypermethrin(CAS No.67375-30-8) is a non-systemic insecticide with contact and stomach action. It has a low aqueous solubility and is volatile. Alphacypermethrin is a pyrethroid insecticide consisting essentially of two of the four cis isomers comprising cypermethrin.

Sogeval, (1992). Residues of Alphacypermethrin (m g/kg) in calves and heifers after the application of 0.15 g in a pour-on preparation. The cis pair of isomers were in a single dose of 1.7-2.5 mg/kg body weight (BW) to 6 females and 6 males. Mean levels rose to 7 m g/l as determined by radio counting and to 5 m g/l as determined by GC, by day 2. The values are the ranges with the mean values in brackets. A gas liquid chromatographic (GC) method was used to determine alphacypermethrin residues in milk (SAMS 456-1). Table 3. Alpha cypermethrin is a synthetic compound belonging to the pyrethroid group of chemicals. Symptoms of exposure include dizziness, nausea, Compared to plasma (80 m g equiv/kg), these levels were significantly higher. Documents related to EPA's review of this pesticide can be found in the following dockets: It is considered a serious marine pollutant. The cis and trans isomers of 14C-alphacypermethrin labeled in the benzyl ring were separately administered to rats by the oral route. Alpha-cypermethrin and zeta-cypermethrin are enriched isomers of the pyrethroid insecticide cypermethrin. The only possible option for a marker substance is the parent compound, alphacypermethrin. The major route of excretion of radioactivity was via faeces, accounting for 34 % of the total administered dose. Approximately 140,000 pounds a.i. All muscle samples contained levels of radioactivity < 30 m g. High levels of total radioactivity were observed in bile (5212 m g equiv/l). 14C-Alphacypermethrin labeled in the benzyl ring was administered orally to one lactating cow via 8 twice daily doses added to a portion of the animal's protein diet at a target dose level of 250 mg/day, ca 19 mg/kg BW. Other Residue Depletion Studies (with unlabeled drug).
