Abstract
The invention discloses a pesticide composition. The pesticide composition comprises an active component A and an active component B, wherein the active component A is spiromesifen, the active component B is any compound selected from the group consisting of pyridaben, propargite, bifenazate and etoxazole, and a weight ratio of the active component A to the active component B is 1: 70 to 70: 1. The composition provided by the invention can prevent and treat a plurality of pest mites, has a substantial synergistic effect, broadens a bactericidal spectrum, reduces the dosage of pesticides, decreases residual quantity of pesticides on crops and mitigates environmental pollution.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of a kind of composition pesticide on crop evil mite.
Technical background
Spiromesifen (Spiromesifen) molecular formula: C
23h
30o
4.The mechanism of action of Spiromesifen is the growth that affects aleyrodid and acarid, disturb the biosynthesis of its liposome, especially larval stage is had to good activity, can also produce ovarian duct closure function simultaneously, the fertility that reduces acarid and adult whitefly, greatly reduces the quantity of laying eggs.
Pyridaben (pyridaben) chemical name: 2-tertiary butyl-5-(chloro-3 (the H)-pyridazin-3-ones of 4-tertiary butyl benzylthio-4-, molecular formula: C
19h
25clN
2oS.This agent is wide spectrum, tagging property miticide, can be used for preventing and treating multiple food vegetalitas evil mite.If to being the whole vegetative period of mite ovum, young mite mite and becoming mite to have good effect, to the one-tenth mite of mobile phase, there is equally obvious speed to kill effect.This medicine is not acted upon by temperature changes, and no matter uses in early spring or autumn, all can reach promising result.
Propargite (Propargite) chemical name: 2-(4-tert-butyl benzene oxy) cyclohexyl Propargyl sulfite, molecular formula: C
19h
26o
4s.Propargite is low toxicity broad spectrum activity organosulfur acaricide, has and tags and stomach poison function, without interior suction and infiltration conduction, if to becoming mite mite effective, the weak effect of ovicidal, this medicine temperature more than 20 ℃ under condition drug effect can improve, but below 20 ℃, with low temperature, falling progressively, propargite can be used for preventing and treating cotton, vegetables, apple, citrus, tea, the harmful mite of the various crop such as flowers, safer to most natural enemies, but want strict controlled concentration, too high easy generation poisoning while using on tender little crop.
Bifenazate (bifenazate), molecular formula: C
17h
20n
2o
3.Bifenazate 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 evil mite.Plant is not poisoned.
Second mite azoles (etoxazole), chemical molecular formula: C
21h
23f
2nO
2.Second mite azoles belongs to 2,4-diphenyl-oxazole derivatives quasi-compound, is a kind of selectivity miticide.Be mainly the process of casting off a skin that suppresses mite class, thereby mite is had to excellent tagging property from ovum, larva to pupa different phase.But not fine to the control efficiency of adult.The mite class that Hexythiazox has been produced to resistance has good control efficiency.
Yet 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 has the seldom composite of synergistic effect, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor's research, after discovery is composite by Spiromesifen and pyridaben, propargite, Bifenazate, second mite azoles, can produce good synergistic effect, and not yet open about the composite relevant report of Spiromesifen and pyridaben, propargite, Bifenazate, second mite azoles.
Summary of the invention
The object of the invention is to propose a kind of have synergistic function, use cost is low, preventive effect is good composition pesticide.
A kind of composition pesticide, contain active components A and active component B, active components A and active component B weight ratio are 1 ︰ 70 ~ 70 ︰ 1, and described active components A is selected from Spiromesifen, and active component B is selected from a kind of in pyridaben, propargite, Bifenazate, second mite azoles; Active components A and the preferred weight ratio of active component B are 1 ︰ 50 ~ 50 ︰ 1; More preferably the weight ratio of Spiromesifen and pyridaben is 1 ︰ 10 ~ 20 ︰ 1, the weight ratio of Spiromesifen and propargite is 1 ︰ 30 ~ 10 ︰ 1, the weight ratio of Spiromesifen and Bifenazate is 1 ︰ 20 ~ 10 ︰ 1, and the weight ratio of Spiromesifen and second mite azoles is 1 ︰ 10 ~ 20 ︰ 1; The weight ratio that most preferably is Spiromesifen and pyridaben is 1 ︰ 4 ~ 8 ︰ 1, and the weight ratio of Spiromesifen and propargite is 1 ︰ 15 ~ 5 ︰ 1, and the weight ratio of Spiromesifen and Bifenazate is 1 ︰ 10 ~ 5 ︰ 1, and the weight ratio of Spiromesifen and second mite azoles is 1 ︰ 4 ~ 8 ︰ 1.
Composition pesticide of the present invention can be processed into acceptable formulation on any agricultural chemicals on demand, and wherein preferred dosage form is wetting powder, water dispersible granules, suspending agent, suspension emulsion, microemulsion, aqueous emulsion, microcapsule suspending agent, microcapsule suspension-suspending agent.
