[{"from": "human", "value": "Please give me some details about this molecule. [C][O][P][=Branch1][C][=O][Branch1][C][N][S][C]"}, {"from": "gpt", "value": "The molecule is a highly active, systemic, residual organophosphate insecticide/acaricide/avicide with contact and stomach action. Its mode of action in insects and mammals is through inhibition of acetylcholinesterase. This enzyme is essential in the normal transmission of nerve impulses. Methamidophos is a potent acetylcholinesterase inhibitor. It is particularly effective against chewing and sucking insects and is used to control aphids, flea beetles, worms, whiteflies, thrips, cabbage loopers, Colorado potato beetles, potato tubeworms, armyworms, mites, leafhoppers, and many others. Crop uses include broccoli, Brussel sprouts, cauliflower, grapes, celery, sugar beets, cotton, tobacco, and potatoes. It is used abroad for many vegetables, hops, corn, peaches, and other crops Due to its toxicity, the use of pesticides that contain methamidophos is currently being phased out in Brazil. Methamidophos is highly toxic via oral, dermal and inhalation routes of exposure. Methamidophos was found in dumplings (gyoza) manufactured in China for the Japanese market after a number of consumers became sick."}]
