Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains multiple killing teichomycin.
Background technology
Multiple killing teichomycin (spinosad), multiple killing teichomycin are the acting bodies of nicotinic acid acetylcholinergic receptor, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Pleocidin also can affect the GABA acceptor, but mechanism of action is unclear.Can make insect benumb rapidly, paralyse, cause at last death.Its desinsection speed can compare favourably with chemical pesticide.Safe, and with present common insecticide be the biological insecticides of low toxicity, efficient, low-residual without cross resistance, existing efficient insecticidal properties has again the characteristic of beneficial insect and mammalian safe is arranged, the most suitable pollution-free vegetable, Production of fruit are used.It is the insecticide of a kind of low toxicity, efficient, wide spectrum.
Spiral shell worm ethyl ester (spirotetramat) chemical name: 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2,5-xylyl)-1-azaspiro [4,5]-last of the ten Heavenly stems-3-alkene-2-ketone, molecular formula: C
