The aims of this work were to monitor the dissipation dynamics organophosphate insecticides applied corn grains stored in supervised experiments, establish and determine minimum period post application necessary comply with established commercial standards. dichlorvos (DDVP), hlorpyrifosmethyl+deltamethrin (CPM) pirimiphos-methyl (PMM) maize grains, which then for 120 days. samples processed ex...

Four commercially available spatial repellent devices were tested in a rice-land habitat near Stuttgart, AR, after semi-field level assessments had been made at the Center for Medical, Agricultural, and Veterinary Entomology, Agricultural Research Service, US Department of Agriculture in Gainesville, FL. OFF! Clip-On(metofluthrin), Mosquito Cognito (linalool), No-Pest Strip (dichlorvos), and Th...

Pesticide residues of organophosphate (OP) and organochlorine (OC) of most commonly used classes were monitored in soil samples collected from cotton growing areas in Nawabshah district, Sindh. All the 19 soil samples presently analyzed were found contaminated with used pesticides (i.e. dichlorvos, dimethoate, methyl parathion, fenitrothion, endosulfan, mevinphos, chlorpyriphos and profenofos) ...

Major uses Chloral hydrate (synthesized in 1832 and introduced into medicine 1869) is the oldest member of sedative-hypnotic drugs. To the same group belong paraldehyde, bromide, urethane, and sulfonal. Metabolite of chloral hydrate, trichloroethanol, is also an excellent hypnotic agent, but is not often used as such due to its physical and irritant properties. At present, chloral hydrate is la...

The relative acute toxicity of Dichlorvos and Cypermethrin acting singly against Rainbow crab, Cardiosoma armatum was evaluated. effects sub lethal concentrations the pesticides on oxidative responses histopathological in gills crab were also investigated over a 30 days period. On basis 96 hrs LC50 value, with hr 8.86 ?g/L 2 times more toxic to crabs than 17.80 ?g/L. exposures (1/10th 1/100th L...

Binding of the endocannabinoid anandamide or of Delta(9)-tetrahydrocannabinol to the agonist site of the cannabinoid receptor (CB1) is commonly assayed with [3H]CP 55,940. Potent long-chain alkylfluorophosphonate inhibitors of agonist binding suggest an additional, important and closely-coupled nucleophilic site, possibly undergoing phosphorylation. We find that the CB1 receptor is also sensiti...
