Abstract
The invention discloses a pyriminostrobin-containing acaricidal composition, the effective components of which are active component A and active component B. Specifically, the active component A is pyriminostrobin, the active component B is any compound of: bifenazate, hexythiazox, spirodiclofen, Fenpyroximate and bromopropylate, and the active component A and the active component B are in a weight ratio of 1:80-60:1. The composition provided by the invention has a synergistic effect on a variety of harmful mites harming agricultural production, decreases the pesticide dosage, reduces the residual amount of pesticides on crops, alleviates environmental pollution, is safe to human and livestock, has good environment compatibility, and is difficult for harmful mites to generate drug resistance.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of miticide composition containing phonetic mite amine on crops evil mite.
Background technology
Phonetic mite amine (Pyriminostrobin) chemical name: 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chlorine pyridazine-3(2H)-one, molecular formula: C

4.If this medicament all has good control efficiency, and has showed excellent ovicidal activity Panonychus citri, two spotted spider mite one-tenth, young mite.
Bifenazate (Bifenazate) molecular formula: C

3.It is a kind of new selective foliar spray miticide, effective to each life stage of mite.There is ovicidal activity and knock down rapidly activity with to what become mite, minimum on predacious mite impact, be very suitable for the comprehensive regulation of insect, plant is not poisoned.
Hexythiazox (Hexythiazox) molecular formula: C

2s; The novel miticide of thiazolidine ketone, has good penetrability to plant epidermis layer, but without interior suction conduction.If the characteristic that various plants evil mite is had strong ovicidal, kills children mite, to becoming mite invalid, has but touch the ovum that the female adult of liquid produces the effect that suppresses hatching.This medicine belongs to non-temperature sensitive type miticide, and the effect using in the time of high temperature or low temperature is without significant difference, and the longevity of residure is long, can remain on about 50 days.
Spiral shell mite ester (Spirodiclofen) molecular formula: C

4, chemical name: 3-(2,4-dichlorophenyl)-2-oxygen-1-oxygen spiral shell [4.5] last of the ten Heavenly stems-3-alkene-4-base-2,2-dimethyl butyrate acid esters; There is the brand-new mechanism of action, show and suppress the synthetic of lipid.All effective to each developmental stage of mite by tagging, comprise ovum.
Fenpyroximate (Fenpyroximate) molecular formula: C

4, chemical name: (E)-4[1,3-dimethyl-(5-phenoxy group-1H-pyrazolyl) methene ammonia oxygen methyl] and benzoic acid-1,1 dimethyl ethyl ester; Stop germ mycelia to invade contiguous healthy cell, and can induce generation disease-resistant gene.When high dose, can directly kill mite class, when low dosage, can suppress the decortication of mite class or lay eggs.There is knocking down and suppress decorticating, without systemic action.
Fenisobromolate (Bromopropylate) molecular formula: C
17h
16br
2o
3, chemical name: 4,4'-dibromo diphenylglycollic acid isopropyl ester; A kind ofly kill that mite spectrum is wide, the lasting period is long, toxicity is low, to the safer miticide of natural enemy, honeybee and crop.Tagging property is stronger, without interior absorption, if to becoming mite and ovum all to have certain lethal effect.Variations in temperature is little on drug effect impact.This medicine is applicable to the crops such as cotton, fruit tree, vegetables and tea, can prevent and treat the multiple harmful mites such as tetranychid, goitre mite, line mite.Evil mite has cross resistance to this medicine and dicofol, when use, will note.
But in the real process of agricultural production, the problem that control evil mite the most easily produces is the drug-fast generation of evil mite.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistance evil mite.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really have a synergistic effect composite seldom, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor's research, find phonetic mite amine and Bifenazate, Hexythiazox, spiral shell mite ester, fenpyroximate or fenisobromolate can produce good synergistic effect after composite, and not yet open about phonetic mite amine and the composite relevant report of Bifenazate, Hexythiazox, spiral shell mite ester, fenpyroximate or fenisobromolate.
Summary of the invention
The object of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect the is good miticide composition containing phonetic mite amine.
