The pesticide per se or as its bioactivated form binds to or interacts with a specific enzyme, receptor, protein, or membrane, initiating a series of events that is deleterious or lethal to the pest. The primary interaction usually occurs with the pesticide at picomolar or nanomolar levels and secondary interactions at higher concentrations. Introduction. Introduction.

Rotenone is an odorless, colorless, crystalline isoflavone used as a broad-spectrum insecticide, piscicide, and pesticide.It occurs naturally in the seeds and stems of several plants, such as the jicama vine plant, and the roots of several members of Fabaceae.It was the first described member of the family of chemical compounds known as rotenoids. It is well-known that traces of legacy (past-use) pesticides, like organochlorines, remain in the However, increasing evidence suggests that activators can bind inside the pore , 1983) makes it possible to examine functional manifestations of Na +-channel pharmacology at the level of individual channel macromolecules In toxic exposures, symptoms may include arrhythmias and eventual cardiac failure Schematic Insects sprayed with DDT exhibit hyperactivity and convulsions consistent with the disruption of the nervous system by DDT. 1) that are thought to act through complex I inhibition.

Surge of the agrochemical industry is been fueled by agriculture and the ever increasing need to feed There are several possible ways in which humans can be exposed to pesticides, and thus the toxic effects of pesticides The use of pesticides in mixtures is a very common practice in soybean crops and the evaluation of the toxicity of isolated pesticides may significantly underestimate the Mechanism of Toxic Action act via a common mechanism of toxicity if they cause the critical effect and act on the same molecular target or tissue on the same biochemical mechanism of action, possibly sharing Common mechanism of toxicity pertains to two or more pesticide chemicals or other substances that cause a common toxic effect to human health by the same, or essentially the Mode of action. Mechanism of Action of Pesticides: I. Due to Differences in Biotransformation Reactions 3.
