Description
Technical field
The present invention relates to agriculture chemical compounding thing, particularly a kind of compounded pesticides containing MTI-446 and pymetrozine.
Background technology
MTI-446,1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine, is the third generation nicotinic insecticide that Mitsui chemical company developed in 1993, and introduced to the market in 2002, but not yet promote the use of at home at present.They are different from the chemical constitution of existing nicotinic insecticide, and it is the novel nicotine of unique not chloride atom and aromatic ring, possess the effect feature of nicotinic insecticide different from the past.MTI-446 has tags and stomach poison function, and strong, the quick-acting height of absorption in root, lasting period are long, and sucking insect is had to excellent preventive effect.In view of MTI-446 has very wide insecticidal spectrum, and fool proof to crop, people and animals and environment, and after extensive generation of resistance of Imidacloprid that is equally anabasine insecticide, being expected to substitute Imidacloprid becomes worldwide widely used anabasine insecticide.
Pymetrozine, 4,5-dihydro-6-methyl-4-(3-pyridine methylene is amino)-1,2, the novel pyridine heterocycle insecticides that 4-3 (2H)-one is Switzerland Novartis Co.,Ltd to be developed in success in 1998, has efficient, low toxicity, high selectivity, the feature such as environmentally friendly.Pymetrozine is novel systemic pesticide, and sucking pest is had to special efficacy as rice fulgorid, aphid etc.Can selectivity block insect's food-taking behavior, make to be subject to poisoning worm to stop immediately taking food, although can also move, because producing irreversible Antifeedant Effects, finally die of starvation, this mode of action is a kind of brand-new neural activity toxicity mechanism; In addition, pymetrozine also has blocking-up insect and passes malicious function, very effective to the insect of control transmitted virus.
Long-term, a large amount of, the single use of chemical pesticide in agricultural production, even abuse, not only cause pesticide resistance sustainable development and the aggravation of pest, make many pests rampant again, the high residue of agricultural chemicals in crop and environment brought day by day serious pollution and harm also to whole ecotope and human health.
Agriculture chemical compounding is that two or more pesticide active ingredient is processed into a kind of preparation by insecticides adjuvant, also can, in field by the agricultural chemicals of two kinds of different active ingredients is mixed to use by a certain percentage, be one of strategy the most frequently used in current Chemical Control of Harmful Insects.Agriculture chemical compounding has synergy, addition, three kinds of distinct results of antagonism, even if composite between two kinds of agricultural chemicals, because the different synergy degree of proportioning are also different, have or even antagonism.Therefore, scientifically the different medicament of two or more mode of action, the mechanism of action is mixed and used, by testing sieve, select the obvious composition of synergy, not only can promote control efficiency, expanding prevention scope, delay the development of pest resistance and the service life of medicament, and can cost-saving, the release of minimizing agricultural chemicals in ecotope.
MTI-446 is considered to a kind of important alternative medicament of Imidacloprid, and control efficiency is good, selectivity is strong, has good application prospect.In order to prevent that following MTI-446 is as Imidacloprid, because causing pesticide resistance, unreasonable use sharply rises, should take ahead of time counter-measure.Pymetrozine is because its unique mode of action is not knocked down activity to insect, and while using separately, although the lasting period is long, quick-acting is slower, and can not reduce immediately field is pests.External interior scholar has carried out the research of some MTI-446 synergistic complex aspects at present, still, there is no MTI-446 and pymetrozine are combined to composite report.MTI-446 and pymetrozine belong to the insecticide of two kinds of completely different types, and the mechanism of action of insect is differed greatly, and meet the selection principle of synergistic complex insecticide composition.Now, by MTI-446 and Pyraphione compound, be provided with a series of compound proportion, through laboratory screening, obtained two significant MTI-446 of synergistic effect and Pyraphione compound ratio.
