Abstract

The invention discloses an acaricide composite containing spirodiclofen and application thereof, comprising (A) a first active ingredient: spirodiclofen and (B) a second active ingredients: propargite; the weight ratio of the first active ingredient and the second active ingredients is 0.01 to 10 : 1. The acaricide composite has reasonable constituent, good acarotoxic effect and low drug cost, and the activity and the acarotoxic effect are not simple sum of the activities of all the constituents but with the advantages of obvious synergistic effect, high quick action, long lasting effect, reducing the generation of resistance to drugs, little residual of preparation, no pollution to crops and good safety and meets the safety requirement of the pesticide preparation. The acaricide composite of the invention has controlling effect of 82.69 to 95.67 percent for red spider in citrous, apple trees and cotton.

Description

A kind of acaricide composition that contains spiral shell mite ester
Technical field
The present invention relates to a kind of miticide composition and application thereof that contains spiral shell mite ester, particularly a kind of comprise contain spiral shell mite ester as first active component and alkynes mite spy as the miticide composition and the application thereof of second active component, belong to technical field of compounded pesticide.
Spiral shell mite ester (english common name spirodiclofen, chemical molecular formula C 21H 24Cl 2O 4) mechanism of action is for suppressing the lipogenesis in the evil mite body, harmful mite is finally killed in the energy metabolism activity of destruction acarid.The characteristics of control are to kill that mite broad spectrum activity, ovum children are held concurrently and killed, the lasting period is long, toxicity is low, safety is good and other miticides do not have cross resistance, and shortcoming is speed of action slow (drug effect peak be behind the medicine about 7 days), to becoming the mite effect undesirable.By China's pesticide toxicity grading criteria, spiral shell mite ester belongs to the low toxicity miticide.Be widely used in various mite class controls, as Panonychus citri, cotton spider mites, the Tetranychus cinnabarinus of Tetranychidae apple, citrus, Tarsonemidae (the many tarsonemids of side), Eriophyidae (thorn apple rust mite, grape rust mite), Tenuipalpidae (grape brevipalpus).But the spiral shell mite ester of selling on city's field boundary is a unitary agent at present, and this unitary agent in use exists easy generation resistance, the defective that the preventive effect cost rises day by day, speed of action is slow.
Alkynes mite spy has another name called the Aomei spy, propargite, english common name propargite, chemical molecular formula C 19H 26O 4S.Alkynes mite spy is the wide spectrum organosulfur acaricide, to becoming mite and if mite preventive effect height.Alkynes mite spy has selectivity, and is safer to honeybee and natural enemy, and quick-acting is good, and the lasting period is general, and toxicity is very low, little to people and animals and natural environment harm.But as a kind of miticide of long-term use, alkynes mite spy has produced resistance in various degree in long-term use, the defective that exists control efficiency to descend.
At present, the pesticidal preparations that with spiral shell mite ester is effective ingredient is based on 240 grams per liter spiral shell mite ester suspending agents, and in actual use, the lasting period is long, but quick-acting is relatively poor, to becoming the mite weak effect; The special quick-acting of alkynes mite is better, and to the one-tenth mite with as if mite preventive effect height, but lasting effect is general, and the unexpected discovery of inventor is mixed two active components to use and can improves its quick-acting, and the good lasting period is arranged again, slows down the generation of pest resistance.
Summary of the invention
One of purpose of the present invention is to provide a kind of miticidal effect good, and drug cost is low, the acaricide composition that contains spiral shell mite ester that is difficult for developing immunity to drugs.
Another object of the present invention is to provide the purposes of above-mentioned composition.
In order to overcome the defective of existing single component formulations, technical scheme of the present invention is to solve like this:

As shown in table 3, to behind the medicine the 7th day the time each sub-district preventive effect carry out the biostatistics analysis, analysis result shows: handle differences and reach extremely outstanding level, district's group difference is not remarkable.Significance of difference comparative result shows: consistent with the significance of difference on 0.01 level on 0.05 level, 15% spiral shell mite ester propargite microemulsion is respectively handled differences with other for 2000 times and is reached utmost point significance level, its 2500 times are not all remarkable with 5000 times of processing of 240 grams per liter spiral shell mite ester suspending agents differences, and 3000 times of 15% spiral shell mite ester propargite microemulsions are not remarkable with 4000 times of processing of the special missible oil of contrast medicament 73% alkynes mite differences.Field trial shows: 15% spiral shell mite ester propargite microemulsion has remarkable prevention effect to cotton red spider, the preventive effect that 15% spiral shell mite ester propargite microemulsion is 2000 times all is better than the preventive effect with 4000 times of the special missible oil of contrast medicament 73% alkynes mite, 5000 times of 240 grams per liter spiral shell mite ester suspending agents, test shows: after spiral shell mite ester and alkynes mite spy are mixed, obviously improved quick-acting and control efficiency, greatly reduced dosage and drug cost cotton red spider.Handle all to cotton growth safety through each concentration of duration of test viewing test, have no adverse effects.
In sum, composition of the present invention is to adopt two kinds of active component compound schemes, and it is active and kill mite Effect is not the simple superposition of each composition activity, compares with existing unitary agent, except having the significant mite that kills Outside the effect, and significant synergistic effect is arranged, quick-acting height, lasting effect are long, slow down the generation of resistance, and be right Crop safety is good, and dosage reduces, and meets the security requirement of pesticidal preparations.
