2S, chemical name (E)-1-(2-chloro-1,3-thiazoles-5-ylmethyl)-3-methyl-2-2-nitroguanidine
Thiophene worm amine by Beyer Co., Ltd and the exploitation of Japanese Takeda Wu Tian company with carrying out global city jointly.This kind is used for paddy rice, fruit tree, tealeaves, turf and views and admires effect in Japan.Thiophene worm amine (clothianidin) is that Wu Tian company is after Nitenpyram (nitenpyram); Another nicotinic insecticide of finding; Belong to the second generation, compare with the nitenpyram of the first generation, the main difference of its molecular structure is: the one, replaced the pyridine group with the chloro thiazolyl group; The 2nd, replaced the Nitromethylene part with nitro-imine.Methyl on 5 has improved the activity of thorn being inhaled insect.2-chloro-5-thiazolyl heterocycle then produces higher effect to the biting mouth parts insect.Thiophene worm amine is wide spectrum, systemic insecticide, is mainly used in paddy rice, vegetables, fruit tree and other crop, control Semiptera, coleoptera, diptera and some lepidoptera pest.
Along with people's deepens constantly pesticide hazards problem understanding, and water-base preparation is paid much attention to.According to world's pesticide industry association statistics, 50% is missible oil in the pesticidal preparations of global marketing at present, and the organic solvent of putting into every year in the environment reaches more than 1,000,000 tons.These non-pesticidal active substances have strengthened the cost of pesticidal preparations on the one hand, and the whole world consumes about 4,000,000,000 dollars every year for this reason.On the other hand, a large amount of organic solvents cause considerable damage to environment.China is second-biggest-in-the-world pesticide producing state, and the annual whole nation produces pesticidal preparations 900,000～1,000,000 ton.China's farm chemical emulsion preparation product accounts for more than 70% of whole preparations, and states such as American and Britain are 20%～30%.China's water-base preparation accounts for the less than 15% of whole preparations, and states such as American and Britain are 30%～40%.Compare China's formulations of pesticide breed structure with other pesticide producing big countries and be faced with stern challenge, also more urgent to the demand of novel water-based preparation variety.Under this background, receive extensive concern with water-base preparations such as suspending agent, microemulsion, aqueous emulsion, aquas, its development technology also becomes current focus.Along with pesticide hazards problem and people become increasingly conspicuous to the concern of living environment, seek to reduce the risk that agricultural chemicals and use thereof bring through the innovation of preparation technique, become the much-talked-about topic of formulation art.
