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 affecting aleyrodid and acarid, disturb the biosynthesis of its liposome, especially have good activity to larval stage, ovarian duct closure function can also be produced simultaneously, reduce the fertility of acarid and adult whitefly, greatly reduce 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, contact acaricide, can be used for preventing and treating multiple food vegetalitas evil mite.If to whole vegetative period of mite and ovum, young mite mite with become mite and have good effect, obvious speed is had to kill effect equally to the one-tenth mite of mobile phase.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 effective to one-tenth mite mite, the weak effect of ovicidal, this medicine drug effect under temperature more than 20 DEG C conditions can improve, but fall progressively with low temperature below 20 DEG C, 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 enemy, but want strict controlled concentration when using on tender little crop, too high easy generation poisoning.
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 activity rapidly 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.Mainly suppress the molting process of mite class, thus have excellence contact from ovum, larva to pupa different phase to mite.But not fine to the control efficiency of adult.Mite class Hexythiazox having been produced to resistance has good control efficiency.
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 has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.Study through inventor, find Spiromesifen and pyridaben, propargite, Bifenazate, second mite azoles is composite after can produce good synergistic effect, and not yet open about the relevant report that Spiromesifen and pyridaben, propargite, Bifenazate, second mite azoles are composite.
Summary of the invention
The object of the invention is to propose a kind of to there is synergistic function, use cost is low, preventive effect is good composition pesticide.
A kind of composition pesticide, containing 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 the one in pyridaben, propargite, Bifenazate, second mite azoles; Active components A and the preferred weight ratio of active component B are 1 ︰ 50 ~ 50 ︰ 1; The weight ratio being more preferably 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 most preferably being 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-suspendinagent agent.
Described composition pesticide is for preventing and treating the application of crops evil mite, and described crops comprise cereal crops, legume crop, oil crop, fiber crop, sugar [yielding, melon crop, fruits crop, dry fruit crop, hobby crop, root crop, flower crop, medicinal crop, crop, green manure pasture crop; Described harmful mite comprises two spotted spider mite, Panonychus citri, tetranychus viennensis, Tetranychus urticae, yellow spider, knurl tick, blister mite, Shenmu-Yanan railway, Tetranychus cinnabarinus, tealeaves mite, tomato goitre mite, rust mite, cotton spider mites, tetranychus telarius, aleyrodid.
In the present composition, the content of active component depends on amount of application when being used alone, and also depends on mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound, simultaneously also relevant with target evil mite.In usual composition, the weight percentage of active component is 2% ~ 90% of gross weight, is preferably 5% ~ 80%.According to different preparation types, active component content scope is different.Usually, liquid preparation contains the active substance of by weight 1% ~ 60%, is preferably 5% ~ 50%; Solid pharmaceutical preparation contains the active substance of by weight 5% ~ 80%, is preferably 10% ~ 80%.
