Abstract
The invention discloses a bifenazate-containing agricultural insecticide composition and an application thereof, wherein, bifenazate is taken as a first active ingredient, any one of fenbutatin or clofentezine is taken as a second active ingredient, and the weight ratio of the first active ingredient to the second active ingredient is 0.01-200:1, preferably 0.2-20:1. The composition has reasonablecomponents, good insect-killing effect, low cost medication, obvious synergic effect, high quick action, long persistent effect, slower resistance generation and good safety on crops, and activity and insect-killing effect thereof are not simple superposition of activity of the components, thus meeting the safety standard of pesticide preparation. The composition has 86.65%-96.38% of control effect on mites on panonychus citri, panonychus ulmi and cotton.
Description
Technical field
The present invention relates to a kind of Pesticidal combination, contain Bifenazate as first active component particularly a kind of comprising, fenbutatin oxide or four mite piperazines belong to technical field of compounded pesticide as the Pesticidal combination and the application thereof of second active component.

3Bifenazate is a kind of γ-An Jidingsuan (GABA) antagonist, mainly prevents and treats the active stage tetranychid, and quick-acting is good, to young mite with become, if mite effective, to some other mite classes, especially Tetranychus urticae is had ovicidal action.Laboratory research shows that Bifenazate does not have negative effect to predatism benefit mite; To the low (LD of mammalian toxicity
50Be 5000mg/kg); Lasting period weak point in environment (DT50＜1d).The Bifenazate of Xiao Shouing is the suspending agent of 480 grams per liters in the market, is mainly used in control apple tree two spotted spider mite.As a kind of new hydrazine ester class specialty miticide, Bifenazate in use exists the use cost height, the risk that resistance risk increases gradually, the defective that lasting period is short, and rationally use with dissimilar miticides, for fully effectively promoting Bifenazate, prolong its service life and have important function.

4Four mite piperazines mainly act on the mite ovum, and young mite is also had certain effect, and are invalid to becoming mite, to the ovum that occurs in panonychus ulmi on fruit tree, cotton, the ornamental plants, congo red spider with if mite is effective, harmless to predation mite natural enemy.This medicine effect is slower, 2 weeks just can reach the highest preventive effect after the general medication, and the lasting period is longer.But four mite piperazines are longer service time, and resistance increases gradually, and are big in the density of mite, effect was not ideal when temperature was higher, and quick-acting is poor, exists becoming the invalid defective of mite.
At present, the pesticidal preparations that with the Bifenazate is effective ingredient is based on 480 grams per liter Bifenazate suspending agents, and in actual use, quick-acting is good, but lasting effect is poor, the use cost height; Fenbutatin oxide quick-acting is better, to young mite with become, if mite preventive effect height, but lasting effect is general, and is little to the lethality of ovum, and four mite piperazines act on the mite ovum, lasting period is long, but poor to quick-acting, invalid to becoming mite, the inventor is unexpected to be found the use that is mixed of Bifenazate and fenbutatin oxide or four mite piperazines can be improved its quick-acting, the good lasting period is arranged again, slow down the generation of pest resistance.
Summary of the invention

Biological Examples 5: citrus red mite indoor virulence test
In order to prevent and treat the insects such as citrus red mite in the agricultural production, we have carried out mutual composite synergy research with compositions such as Bifenazate, fenbutatin oxide, four mite piperazines.It is tested object that citrus red mite is adopted in test, and concrete grammar is:
Citrus red mite (panonychus citri, formal name used at school Panonychus citfi McGregor) the former medicine of test medicine Bifenazate adopts the former medicine of U.S. Chemtura Corporation production, the former medicine that the former medicine of fenbutatin oxide adopts Zhejiang Prov HeBen pesticide Chemical Co., Ltd to produce, the former medicine that the former medicine of four mite piperazines adopts Jiangsu Province Nantong Baoye Chemicals Co., Ltd. to produce, by my technology department of company former medicine is mixed with the test medicine that needs, the test method reference " (the agricultural industry criteria NY/T1282-2007 of the People's Republic of China (PRC) ".At first single agent and each Mixed Pharmacy are provided with 5 variable concentrations gradients (on preliminary experiment result's basis, citrus red mite becomes the mite lethality to set by geometric progression) in 5%～90% scope.The examination worm is the one-tenth mite of picking up from the field, select the one-tenth mite of uniformity in the length of time in the laboratory, put into blade-carrying culture dish, every ware 40 cephalont, 4 culture dishes of every processing, repeat 3 times, under 50PSI pressure, spray, spray a ware at every turn with the potter spray tower, every ware spraying liquid 3ml, the culture dish that to handle is put into the 12H/12H illumination box and is cultivated then, checks in 48 hours to calculate lethality by dead borer population.Blank spray equivalent clear water.The co-toxicity coefficient of mixture (CTC value) calculates by following formula:
