Surprisingly in view of the radiometric data, residues were not measured in the subcutaneous fat at the site of application in the pour-on studies. The radioactivity in the tissues was determined at 3 days post-dosing. Residues were less likely to be found in muscle and liver, occasionally residues were observed in kidneys, residues were mostly associated with body and milk fat. How old is patient? For animals of more than 400 kg: 20 mL/animal; sheep and camelids (up to 45 days post shearing) 5 … There are in progress investigations into the use of the compound to control sea-lice infestations in farmed fish. 79.117 Residues of Barricade (Cypermethrin) in cattle from Australia. The majority of the total residues in the fat of rats after oral administration for 8 and 25 days was unchanged Cypermethrin (Crawford and Hutson, 1978). Two detailed analytical methods were submitted, one for cypermethrin (LOQ was 10 m g/kg) and 3-phenoxy benzoic acid (LOQ was 50 m g/kg) in tissues and one for cypermethrin (LOD was 2 m g/l) in milk. A summary of the radioactive residue values is provided in Table 5. A significant proportion (> 90%) of the bound residues could be liberated to yield the same metabolites as in the free fraction (Croucher, Hutson, and Stoydin, 1985). Treat symtomatically. It is relevant, in this context, that 3-phenoxybenzoic acid, when dosed to rats, appeared (in low concentration) in the skin as a mixture of triglycerides including the 3-phenoxybenzoyl dipalmitoyl glycerols (Crayford & Hutson, 1980). Mean Residues of Cypermethrin in calves administered 0.5 g Cypermethrin in a pour-on preparation. Faecal radioactivity was 88% extractable into organic solvent. Compatibility: CYPERMETHRIN is compatible with a wide range of pesticides. Apply post emergence over the row as a 30 cm band in 3 litres water per 100-meter row.

The metabolic fate of WL 43467 (cypermethrin). 100 ml / ha Overall application in 300 litres water per hectare or aerial application in 30 litres water per hectare. Cypermethrin, a synthetic pyrethroid, is used as pesticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. BLGR. Total residues (m g/kg) of 14C-Cypermethrin in orally dosed cattle slaughtered on the last day of dosing. However, the highest residue in fat was 180 m g/kg with most of the values < 100 m g/kg. Residues persisted throughout the 15 days post-dipping period. Cypermethrin 10% emulsifiable concentrate (EC) when sprayed at the concentration of 100 g ai ha −1 showed a residue level of 0.71 mg kg −1 at 0 day followed by 0.52 mg kg −1 at 1 day in dry season, which were higher than the recommended MRL of 0.5 mg kg −1 set for beans with pods. Residues in tissues were comparable except for liver and kidney where higher values were observed in the tissues from the orally-dosed animals. The JMPR in 1981 set an ADI for Cypermethrin of 0.05 mg/kg/day which equates to a daily intake of 3 mg for a 60 kg person. Bound residues in kidney were less than 10 m g/kg and were not further investigated. Recoveries of spikes of 5 and 10 m g/l were 99 ± 8% (Baldwin et al., 1977d). Residues of cypermethrin in cattle milk in New Zealand. Table 2. SAMS 341-1. Confirmatory methods using GC-MS are contained in the submitted papers.

Chemical Name: [RS]-α-cyano-3-phenoxybenzyl (1RS)-Cis-trans-3-(2, 2 dichlorovinyl)-2, 2-dimethyl cyclopropane carboxylate. Radioactive residue in fat that was removed by solvent extraction was 98%; in addition, 90% of the fat residue was shown to be the parent Cypermethrin. The limits of determination (LOQ) for Cypermethrin were claimed (no data) as 10 m g/kg and 50-100 m g/kg for 3PBA. Surprisingly in view of the radiometric data, residues were not measured in the subcutaneous fat at the site of application in the pour-on studies. Two male sheep were topically treated (21.9 mg/kg BW) while a third was orally dosed (3.9 mg/kg BW) with labeled in the cyclopropyl and benzyl positions, see Table 3 (Crawford and Hutson, 1977b). Cattle: 10 mL/animal. [71], Bosio, P.G., (1979a). Hutson and Stoydin, (1987). 3. Group Research Report TLGR. Poisonous when swallowed and moderately toxic by skin contact. 80 % radioactivity was extracted with hot methanol from liver. There were residues (up to 130 m g/kg) in the kidneys throughout the 14 days post dosing study period and much higher levels were found in both peritoneal and subcutaneous fat.

Less than 0.5% of the dose was excreted in urine within 24 h and only 2 % over a six day period. [46]. However Cypermethrin is toxic to aquatic life and it is important to avoid contamination of surface waters. 82.001. The extract was further hydrolysed to liberate free metabolites, especially 3PBA and 4HO3PBA from their conjugates. [50], Crawford, M.J. and Hutson, D.H., (1978). The residues were measured in whole milk for 21 days after applying a dose of either 0.5 g or 1 g as a pour-on preparation to lactating cows. Cypermethrin was slowly absorbed and eliminated when applied topically to sheep. The dosage recommended by the WHO is 0.02–0.03 g/m 2, giving a residual effect of 4–6 months (World Health Organization, 2007a). Table 12. Cypermethrin is a carboxylic ester resulting from the formal condensation between 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid and the alcoholic hydroxy group of hydroxy(3-phenoxyphenyl)acetonitrile. The major metabolites were in the cis form from the cis isomer, namely DCVA (36 % of radioactivity) as the free or glucuronide conjugate or the parent compound (30 %). The residues in eggs reached plateau values about 6 days after the start of administration of radiolabel. The residue in milk was 90% extractable and shown to be Cypermethrin. SBGR. A level of 92% of the kidney residue could be extracted with methanol at room temperature. Thus residues in larger animals may be lower. Everdeath. ), Wallace, B.G., (1980).

Residues were measured in the whole milk of ewes after dipping once using a 0.015% formulation. A higher contribution was observed in fat as compared to the muscle and organ tissues; the results are summarized in Table 2. Okra. The metabolic fate of cypermethrin in the cow. All Rights Reserved (Terms of Use) Developed and Managed by IndiaMART InterMESH Limited. TLGR. The majority (80%) of the radioactive residue in muscle was extracted by methanol, but the extract was not further investigated since the residue level amounted to < 10 m g/kg. BLGR. The residues in calf tissues are shown in Table 10. et al., (1981). Cypermethrin drug & pharmaceuticals active ingredients names and forms, pharmaceutical companies. Cypermethrin may be applied orally or topically (ear tag, dipping, spraying, pour-on). 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. White (1987). The residues although still present at 14 days were declining. Product Details :-Description: Cypermethrin is a highly active synthetic pyrethroid insecticide.It controls a wide range of insect pests on a variety of crops by stomach and contact action. 160 - 280 80 - 120 80 - 120. Residues were found in both the perirenal fat (< 10 to 150 m g/kg) and omental fat (< 10 - 130 m g/kg). Residues were measured in whole milk in Study 11 for up to 21 days post dosing. [70], Perret, G.R., (1982). A method for the determination of Cypermethrin and 3PBA in the edible tissues was submitted. Cypermethrin 200EC 1L. In another study rats were administered 1-2 mg/kg BW of either cis or trans 14C-Cypermethrin and the metabolites investigated. Residues of the pyrethroid insecticide WL 43467 in tissues of cattle following a dip-bath application. Thus it is not possible to determine the depletion of the total residues in these species. Cypermethrin is a synthetic pyrethroid insecticide used to kill insects on cotton and lettuce, and to kill cockroaches, fleas, and termites in houses and other buildings. Residues of Barricade (cypermethrin) and Supona (chlorfenvinphos) in cattle from Australia. Thank youYour Enquiry has been sent successfully. Disposit. 88.001. In recommending MRLs the Committee took account of the following factors: - The marker residue is parent drug, cypermethrin; - Fat, milk and eggs are marker tissues but muscle, liver and kidney should be considered; - The metabolism and radiodepletion studies are not adequate and, therefore, very conservative estimates of the marker compound as a percentage of total residues in all food species is proposed. Residues of Cypermethrin in bovine tissues, showing the maximum concentrations found in m g/kg or l. No residues were detected in all four edible tissues. Residues (m g/kg) of 14C-Cypermethrin in four laying hens and their eggs. [47], Hutson, D.H. & Stoydin, G., (1979). When sheep received the pour-on application the residues in the subcutaneous fat at the site of application were more than ten fold higher than following an oral dose. Excretion and Residues of the Pyrethroid Insecticide Cypermethrin in Lactating Cows, Pestic. Crawford, (1978); 3. Higher residues were observed in fat (mean concentration was 90 m g/kg at 7 days post dosing) and in the milk fat (mean peak value was 110 m g/kg at 4 days post dosing) and had declined to a mean value of 30 m g/kg by day 10. The study was made using a dose which at 0.5 g per 125 kg calf was the same amount as that recommended for larger mature animals. The mean values in m g/l at 1, 3, 7, 10 and 15 days were 13, 10, 9, 7 and 7, respectively. The commercial formulations are in the form of ear tags, sprays, dips and pour-on formulations. Bollworm Jassids Thrips. In all species after oral administration there was evidence of hydrolysis of the ester bond and residues of each part of the molecule were found in different proportions in rats, cattle, poultry and humans. Residue data following the application of WL 43467 for nuisance fly control on cattle. For example, 98-101 % of the radioactivity derived from the 14C-benzyl-labeled compounds could be recovered in 3 days (Crawford and Hutson, 1977a). This component behaved as a lipid in that it was retained in hexane when cypermethrin was extracted from hexane into acetonitrile. Metabolite analysis on tissues was derived from the 10.0 mg/kg diet dose study (Hutson, 1980). Residues were measured in hens over a 14 day period after applying either a dose of 10 or 20 mg per bird as a spray. Residues of Cypermethrin in laying hens after spraying with Cypermethrin, Range of Cypermethrin (m g/kg) n = Crawford, M.J. and Hutson, D.H., (1977a). Check specific product labels for details. ; Formulations: Emulsifiable concentrates 5%, 10%, 20% and 25% (w/w) and (w/v) Cypermethrin is a synthetic pyrethroid used for the control of ectoparasites which infest cattle, sheep, poultry and some companion animals. In addition, eggs were collected from each group, from 3-day periods, between treatment and sacrifice. The residues in fat were highest (mean 90 m g/kg) at 7 days post dosing. Mistblower: Use the lower dosage on cotton less than 60 cm high and the higher dosage rate on cotton taller than 60 cm. Shoor & fruit borer, jassids, Epilachna grub. Three studies (see excretion section above) were carried out on lactating cows in which 14C-Cypermethrin was fed in the diet. Residues were at or below the LOQ in muscle, liver, kidney and eggs but were present in fat and skin throughout the 14 day post dosing period. Fresh vegetables are of the focal points of this study, since they are a significant source of phenolic antioxidants. The total radioactivity in whole eggs reached maximum values, 50-70 m g/kg expressed as parent drug equivalents, between 5-8 days on treatment and remained at this level for the remainder of the dosing period (see also radiodepletion studies). There were virtually no residues when ear tags were used, some residues were seen in fat and milk fat with both the spray and dip treatments, the highest and most persistent residues were found with the pour-on preparations. The lipophilic character of the cis and trans-isomers are likely to be very similar and therefore it is not immediately obvious why the trans-isomer is released from fat more quickly than the cis-isomer (Crawford and Hutson, 1977a). 87 001. [69], Braun, H.E., Frank, R. and Miller, L.A., (1984). The milk fat was about 5.8% of the milk and if all the residues are in the fat then the maximum concentration in the fat was 206 m g/kg on day 1 and also a high value of 143 m g/kg was seen on day 7. Bosio (1981a); 5. All the samples were analysed for residues of Cypermethrin (Bosio, 1981b). Crawford, M.J. and Hutson, D.H., (1977b). Cypermethrin is a mixture of all eight possible chiral isomers. Cypermethrin is toxic to the nervous system. 1981 Trials. What are common uses for Cypermethrin? The maximum concentrations in m g Cypermethrin equivalents/l were 1.2, 13.1 and 31 for the cows receiving 0.2, 5 and 10 mg 14C-Cypermethrin/kg feed, respectively. Original concentration of radioactivity was 0.216 mg 14C-Cypermethrin/kg, thus about 85 % of the residues were isolated and approximately 77 % of the residue identified. Samples of milk are treated with potassium oxalate solution, ethanol, diethyl ether and hexane. 36 of 1947 An emulsifiable concentrate ... even at a corrective dosage rate. The Indonesian MoH recommended alpha-cypermethrin wettable powder (WP) at a dosage of 0.02 g/m 2 for IRS (Departemen Kesehatan, 2003c, 2010). Of the tissues analysed, the liver contained the highest residue (370 m g/kg) of which only 50 m g/kg was accounted for as cypermethrin. Dosage Residues were measured in the whole milk of ewes after dipping once with a 0.015% formulation (Study reference 4, Table 11). 150 - 200 150 - … When the cis and trans isomers of Cypermethrin were dosed orally to rats, both were metabolised and eliminated rapidly.
