Diazinon 二嗪磷 

Introduction: Diazinon is a non-systemic organo-phosphate insecticide used on home gardens and farms to control a wide variety of sucking and leaf eating insects. It is used on rice, fruit trees, sugarcane, corn, tobacco, potatoes and on horticultural plants. It is also an ingredient in pest strips. Diazinon has veterinary uses against fleas and ticks. Nearly 2.6 million pounds of diazinon were used each year prior to 1983. Some of the older formulations of diazinon were unstable and contained a number of potent impurities such as sulfotepp and monothiono-TEEP. Newer products do not contain impurities which increase the risk associated with diazinon use. In 1988 EPA cancelled the registration of diazinon for use on golf courses and sod farms. They cited die-offs of birds which often congregate in these areas.

ENVIRONMENTAL FATE
EHC 198 (WHO 1998), 63 (WHO, 1986; a general review of organophosphorus insecticides). Animals The principal metabolites are diethyl thiophosphate and diethyl phosphate. Plants Studies with 14C-labelled diazinon show a rapid absorption and translocation in plants. Metabolism proceeds via hydrolysis and subsequent transformation and degradation of the hydroxypyrimidine derivatives to CO2. Soil/Environment Degradation involves oxidation to the phosphate (diazoxon) and hydrolysis (J. Pardue et al., J. Agric. Food Chem., 1970, 18, 405-408). DT50 c. 11-21 d (laboratory). Diazinon is fairly strongly adsorbed onto soil; Kom 332 mg/g o.m. Mobility is low. 

Usage: Diazinon is a thiophosphoric acid ester developed in 1952 by Ciba-Geigy, a Swiss chemical company (later Novartis and thenSyngenta). Diazinon is  used to control pest insects in soil, on ornamental plants, and on fruit and vegetable field crops.

Application: Diazinon is a non-systemic organophosphate insecticide. Biochemistry Cholinesterase inhibitor. Mode of action Non-systemic insecticide and acaricide with contact, stomach, and respiratory action. Uses Control of sucking and chewing insects and mites on a very wide range of crops, including deciduous fruit trees, citrus fruit, vines, olives, bananas, pineapples, vegetables, potatoes, beet, sugar cane, coffee, cocoa, tea, tobacco, maize, sorghum, alfalfa, flax, cotton, rice, ornamentals, glasshouse crops, forestry, etc., at 300-600g/ha; soil insects (by soil application); phorid and sciarid flies in mushroom cultivation; flies, lice, mites, fleas, cockroaches, bedbugs, ants, and other insect pests in animal houses and household use. Seed treatment for maize, for control of frit flies and also conferring bird-repellent properties. Also used as a veterinary ectoparasiticide.
