Abstract
The invention relates to an insecticidal synergistic composition containing benzoylurea inhibitors, which contains two kinds of active ingredients for synthesizing the inhibitors, namely a compound of formula (I) and a benzoylurea chitin, in a synergistic effective dose ratio. The benzoylurea chitin may be lufenuron, hexaflumuron, chlorfluazuron, flufenoxuron and chlorbenzuron. When the two kinds of pesticides are used in combination, the dose of each kind of pesticide can be reduced; and when used for killing pests and mites, the composition has high synergistic effect.
Description
Technical field
The invention belongs to the composition pesticide field, relate to particularly a kind of agricultural chemical composition for disinsection and application thereof, particularly relate to a kind of purposes that comprises insecticidal synergistic composition and the control crop pest thereof of benzoyl area kind inhibitor.
Background technology
The benzoyl area kind chitin synthesis inhibitor enough suppresses the activity of insect chitin synthetase, hinders chitin synthesis, makes casting off a skin, pupating to be obstructed of insect, and activity slows down, and takes food minimizing, eventually to dead.The benzoyl area kind chitin synthesis inhibitor is efficient to lepidopterous larvae, and the lasting period is long, and to higher mammal safety, meets the development trend of environment friendly agricultural.Lufenuron, HEXAFLUMURON, fluorine pyridine urea, flufenoxuron and the young urea that goes out are five kinds of important benzoyl area kind chitin synthesis inhibitor kinds.The shortcoming of benzoyl area kind chitin synthesis inhibitor is that speed of action is slow, generally just can reach peak mortality in 3 to 7 days behind medicine, and this has limited the use of benzoyl area kind chitin synthesis inhibitor to a certain extent.And through single for many years use, particularly diamond-back moth is very fast that the benzoyl area kind chitin synthesis inhibitor has been produced pesticide resistance for insect.
Hydroxy methylimidazole alkane-2, the 4-derovatives, have insecticide and miticide activity such as its carboxylic acid ester compound, it can effectively kill housefly and cockroach, acarid also had certain preventive effect, but no matter be desinsection or kill mite, its preventive effect phase is shorter, can obtain better effect if can mix to use with long insecticidal/acaricidal agent of preventive effect phase.
Summary of the invention
The technical problem that solves
The technical problem to be solved in the present invention provides a kind of benzoyl area kind chitin synthesis inhibitor and hydroxy methylimidazole alkane-2 of comprising, the insecticidal synergistic composition of 4-derovatives, with the usage amount that reduces agricultural chemicals, the insecticidal spectrum that enlarges agricultural chemicals, reduce insect to single resistance of planting agricultural chemicals, prolong the preventive effect phase when guaranteeing quick desinsection, reduce a large amount of applying pesticides to the harmful effect of environment.Overcome the defective such as single plant that pesticide species is applied to that the dosage in farmland is large, resistance, insecticidal spectrum are narrow.
Technical scheme
For solving the problems of the technologies described above, the present invention has obtained a kind of insecticidal synergistic composition through great many of experiments, said composition comprises and has as shown in the formula (I) compound and two kinds of active components of benzoyl area kind chitin synthesis inhibitor, wherein active component formula (I) compound and benzoyl area kind chitin synthesis inhibitor exist with the ratio of synergy effective dose
The benzoyl area kind chitin synthesis inhibitor is selected from a kind of in lufenuron, HEXAFLUMURON, fluorine pyridine urea, flufenoxuron and the young urea that goes out.
Particularly, the weight ratio of composition Chinese style (I) compound and benzoyl area kind chitin synthesis inhibitor is 1: (0.02-50), especially particularly, the weight ratio of formula (I) compound and benzoyl area kind chitin synthesis inhibitor is 1: (0.025-30), especially particularly, the weight ratio of formula (I) compound and benzoyl area kind chitin synthesis inhibitor is 1: (0.1-10).
The above-mentioned composition that comprises formula (I) compound and the young urea that goes out can also comprise other one or more pesticide activity components, other pesticide activity component such as insecticides, fungicide, synergist, weed killer herbicide or plant growth regulator etc., preferably, above-mentioned composition comprises one or more other pesticide active ingredients.
Other suitable insecticide can be pyrethroid, natural pyrethrins, organophosphorus ester, such as the first Toyodan, carbamates is such as carbofuran, furathiocarb etc., macrolide is such as Olivomitecidin, the close mycin that compares, organochlorine compound, such as 5a,6,9,9a-hexahydro-6,9-methano-2,4, lindane etc., the amidine class is such as galecron, two worm amidines etc.
The present invention also provides above-mentioned composition to be used for the control insect that harms the crops and the purposes that does harm to mite, the purposes of especially preventing and treating apple diamond-back moth and tetranychid, and above-mentioned composition also has preferably preventive effect to housefly and Germany cockroach.
The present invention also provides a kind of method of pest control, and the method comprises with the insecticidal effective dose above-mentioned composition processes above-mentioned insect, its provand source, its habitat or its breeding spot or wherein insect growth or may growing plants, seed, soil, zone, material or environment or will prevent the insect invasion and attack or material, plant, seed, soil, surface or the space of infecting.
Above-mentioned composition of the present invention also comprises suitable inert diluent or other non-active ingredients such as carrier and surfactant.Preferably, the active component sum accounts for the 0.0001-95% of composition total weight in the composition, preferred 1-70%, especially preferred 1-20%
The composition that comprises other non-active ingredients can be mixed with the preparations such as missible oil.
Above-mentioned composition of the present invention is used after two or more active components can being mixed, perhaps with two or more active components with use after other non-active ingredients mix, also can be with active component successively, can use first formula (I) compound, then use the young urea that goes out in insect, perhaps use first the young urea that goes out, use again formula (I) compound, perhaps two or more active components are mixed with respectively certain formulation, bucket is used after mixing immediately before pest control.
Formula among the present invention (I) compound can be by CN101516855A the method preparation of Preparation Example 1 of specification.Its chemical name is: 2,5-dioxo-3-(2-propynyl) imidazolidine-1-ylmethyl (1R)-trans-3[(E)-and 3-methoxyimino-2-methyl-1-propylene base]-2,2-dimethyl cyclopropane carboxylic acid ester.
Beneficial effect
Composition pesticide of the present invention compared with prior art produces following beneficial effect:
(1) two kind of agricultural chemicals mixes when using, and is reaching in the situation of identical preventive effect, can reduce respectively the amount of application of every kind of agricultural chemicals, and namely two kinds of agricultural chemicals show the effect of synergy when being used for Insecticiding-miticiding;
(2) mix the preventive effect effect use the antagonism insect remarkable, especially to the control of diamond-back moth and apple tetranychus, effect is remarkable.
