Description

Rynaxypyr and emamectin benzoate insecticidal composition
Technical field
The present invention relates to a kind of Pesticidal combination, particularly a kind of Synergistic fertilizer Pesticidal combination that contains Rynaxypyr and emamectin-benzoate.
Background technology
Rynaxypyr (Chlorantraniliprole) is first broad spectrum pesticide with novel mebenil yl-benzamide class chemical constitution, and this insecticide has unique chemical structure, the novel mode of action, the biological property and the environmental ecology safety of high-efficiency broad spectrum.Rynaxypyr can effectively be prevented and treated nearly all important lepidoptera pest and other insect of part; larvicidal activity and lasting effect provide outstanding crop protection effect efficiently for they; rice-stem borer, paddy stem borer and rice leaf roller there is special efficacy; all effective to rice thrips, rice silk worm first, rice plant skipper and pink rice borer, the lasting period is more than 20 days.Rynaxypyr has rapid prevention insect feed, efficient activity and the good resistance of rainwater washing against performance of being detained, and has realized the quick-acting of plant protection and good lasting effect.The unique novel mode of action of Rynaxypyr is by activating the ryania acceptor in the insect muscle, cause the internal calcium ion unrestrictedly to discharge, stop contraction of muscle, thereby make insect stop to get food rapidly, muscular paralysis, vigor disappearance, paralysis appear, until thorough death, insect stops harm from getting to eat, and only needs about 7 minutes time.Especially the insect to conventional pesticide generation resistance has special efficacy and natural parasitic wasp, natural enemy and insect pollinator is had good selectivity, toxicity to mammal, fish and birds is extremely low, this makes Rynaxypyr be particularly suitable for the insect comprehensive regulation (IPM), helps the good quality and high output of grain.Rynaxypyr is high because of insecticidal activity, sets up the new mark post of insecticide, but its mu is higher with cost, has limitation in actual applications.Its chemical name is: 3-bromo-N--1-(3-chloropyridine-2-yl)-1-hydrogen-pyridine-5-formamide, and its chemical structural formula is as follows:
Emamectin-benzoate (Emamectin benzoate) is called for short first dimension salt, is a kind of antibiotic insecticide, is that the Avermectin hydroxyl is derived and formed.Have efficient, wide spectrum, a drug can be prevented and treated various pests, and the speed of desinsection is slower, and the lasting period is long.Its mechanism of action is to hinder pest movements nerve information transmission and make the health paralysis, and the mode of action is based on stomach toxicity and tag, and can effectively infiltrate the leaf tissue of target crop, to natural enemies security, easily degraded, noresidue, to the person poultry safety, can with most of combined use of pesticides.The existing many at home enterprises of first dimension salt produce, application area on crop is also increasing year by year, but because of to fishes and shrimps, honeybee toxicity height, the use in places such as water sources is subjected to certain limitation, and nearly 2 years continuous use, the insect of some crops has also produced certain resistance.Its chemical structural formula is as follows:
Figure A20091002254200042
The synergistic complex of agricultural chemicals is expanding prevention spectrum, raising preventive effect and the effective measures that reduce peasant's drug cost, the inventor furthers investigate the mixture preparation of Rynaxypyr and first dimension salt, found that the mixture preparation of Rynaxypyr and first dimension salt has strong synergy.Especially the most obvious with the synergy that is mixed of the ratio of Rynaxypyr and emamectin benzoate-chlorfenapyr active ingredient (10: 1~1: 1), co-toxicity coefficient reaches more than 200.Finished the present invention based on above research and discovery.
Summary of the invention
