Pesticide degradation is the process by which a pesticide is transformed into a benign substance that is environmentally compatible with the site to which it was applied. Globally, an estimated 1 to 2.5 million tons of active pesticide ingredients are used each year, mainly in agriculture .
General chemical structure of the organophosphate functional group. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P(OR) 3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric ...
Also derivatives containing the thiophosphoryl group (P=S) include the pesticide malathion. The organophosphates prepared on the largest scale are the zinc dithiophosphates, as additives for motor oil. Several million kilograms of this coordination complex are produced annually by the reaction of phosphorus pentasulfide with alcohols. [6]
Under a 1988 amendment to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), the U.S. Environmental Protection Agency (EPA) regulates organophosphate pesticides [48] Its focus was initially on registering pesticides for use on food crops. No pesticide can be sold in the United States before the EPA has reviewed the manufacturer's ...
Methamidophos, trade name "Monitor," is an organophosphate insecticide.. Crops grown with the use of methamidophos include potatoes [1] and some Latin American rice. [2] Many nations have used methamidophos on crops, including developed nations such as Spain, United States, Japan, and Australia.
Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals).
In a study published in Genome Biology, [6] researchers demonstrated the gut microbiota mediated diabetogenic effect of organophosphate insecticides. They used monocrotophos as the prototypical organophosphate in their study and showcased that during chronic intake, monocrotophos is degraded by the gut microbiota and the end products are converted to glucose via gluconeogenesis that account ...
Bensulide is a selective organophosphate herbicide. It is one of a few organophosphate compounds that are used as an herbicide. Most of the others are used as insecticides. It is used on vegetable crops such as carrots, cucumbers, peppers, and melons and in cotton and turfgrass to control annual grasses such as bluegrass and crabgrass and ...
