Phosalone 伏杀硫磷

Introduction: Phosalone was introduced in 1963 by Rhone-Poulenc company as a nonsystemic insecticide and acaricide for use on deciduous fruit trees, market garden crops, cotton, potatoes and rape. It is a broad-spectrum pesticide with rapid killing ability. Approximately 12-20 days control may be expected. Phosalone is a member of the organophosphate family of insecticides. It is used as both an insecticide and acaricide. It comes in emulsifiable concentrate, wettable powder and dust formulations. It is used on nut crops, citrus, pome fruits, stone fruits, grapes, potatoes, artichokes, roses and arborvitae. It is active against the red spider mite on apples and pears. It controls a wide range of caterpillars and beetles on crops of economic importance as well as a number of hemiptera and hymenoptera.

ENVIRONMENTAL FATE

Breakdown of Chemical in Soil and Groundwater: Phosalone rapidly degraded (t1/2 = 3-7 days) in flooded Metapeake loam and Monmouth fine sandy loam. Mineralization to carbon dioxide accounted for only 10% of the loss. The primary degradative pathway proceeded by oxidation of phosalone to give phosalone oxon. Subsequent cleavage of the O,O-diethyl methyl phosphorodithioate linkage gave 6-chloro-2- benzoxazolinone. Phosalone is stable at pH 5 and 7, but is hydrolyzed at a pH of 9 with a half-life of 9 days. Phosalone does not move in soil and degrades rapidly when compared to parathion. Aerobic soil metabolism studies demonstrate half-life values of 1-7 days. Field dissipation studies showed half-life values of 1-9 weeks. Phosalone was essentially immobile in a soil column test. Based on this preliminary data, phosalone appears unlikely to contaminate groundwater. Breakdown of Chemical in Surface Water: Phosalone rapidly dissipates in untreated waters. Breakdown of Chemical in Vegetation: Phosalone degrades in plants to chlorbenzoxazolone, formaldehyde, and diethyl phosphorodithioate. It persists on plants about 14 hours, being converted to the corresponding phosphorothioate which is rapidly hydrolyzed. Phosalone is not phytotoxic under normal conditions.

Usage: Phosalone was developed by Rhone-Poulenc company. It is An insecticide and acaricide used to control Coleoptera, Homoptera, Lepidoptera and other pests mainly on potatoes, artichokes, nuts, fruit including citrus, apples, pears, plums, apricots, grapes, nuts, roses, etc.
Application: Biochemistry Cholinesterase inhibitor. Mode of action Non-systemic insecticide and acaricide showing localised penetration of plant cuticle; with contact and stomach action. Uses A non-systemic acaricide and insecticide used primarily in pome and stone fruit trees. Effective against Coleoptera, Homoptera (Aphididae), Lepidoptera (Cydia pomonella) and Thysanoptera on fruit trees. It is selective of most beneficial insects and widely used in integrated pest management programmes. Also used in grapes, oilseed rape, ornamentals, potatoes and vegetables.
