Environmental Fate of Carbaryl
The document reviews the environmental fate and environmental effect of carbaryl (1-naphthyl-N-methyl carbamate). Carbaryl is one of the most frequently used carbamate insecticides and widely used for the control of a variety of pests on fruit, vegetables, forage, cotton and many other crops, as well as on poultry, livestock and pets (Mathew et al., 1995). It is available as wettable powders, p...
متن کاملPurification and characterization of the N-methylcarbamate hydrolase from Pseudomonas strain CRL-OK.
A unique cytosolic enzyme that hydrolyzes the carbamate linkage of the insecticide carbaryl (1-naphthyl N-methylcarbamate) was purified from extracts of Pseudomonas sp. strain CRL-OK. Substrates of the hydrolase include the N-methylcarbamate pesticides carbofuran and aldicarb but not the phenylcarbamate isopropyl m-chlorocarbanilate, the thiocarbamate S-ethyl N,N-dipropylthiocarbamate, or the d...
متن کاملCharacterization of varicella-zoster virus enhancement by the pesticide carbaryl.
Further characterization of the viral enhancement system of varicella-zoster virus by the pesticide carbaryl (1-naphthyl-N-methylcarbamate) is presented. It was necessary to expose cells to the enhancing chemical during the period of virus replication to detect enhancement. The optimum time for the pretreatment is 20 to 24 h. Maximum enhancement of virus expression occurs 48 to 72 h post-inocul...
متن کاملInsights into functional and evolutionary analysis of carbaryl metabolic pathway from Pseudomonas sp. strain C5pp
Carbaryl (1-naphthyl N-methylcarbamate) is a most widely used carbamate pesticide in the agriculture field. Soil isolate, Pseudomonas sp. strain C5pp mineralizes carbaryl via 1-naphthol, salicylate and gentisate, however the genetic organization and evolutionary events of acquisition and assembly of pathway have not yet been studied. The draft genome analysis of strain C5pp reveals that the car...
متن کاملThe metabolism of the insecticide carbaryl (1-naphthyl N-methylcarbamate) by fat body of the blowfly larva Calliphora erythrocephala.
1. Carbaryl is metabolized more rapidly by fat body of the blowfly larva than by gut, muscle, cuticle or haemolymph. 2. Metabolism of carbaryl by the fat body is affected by the age of the larva, the pH of the incubation medium, and the concentration of magnesium chloride in the incubation medium. 3. Chloramphenicol, 2,4-dinitrophenol and 5-dimethylamino-6-nitro-1,3-benzodioxole (a carbaryl syn...
