Abstract
The invention discloses a bifenazate-containing insecticidal composition. Active components comprise bifenazate and clofentezine, wherein the weight ratio of the bifenazate to the clofentezine is 0.01-200:1, preferably 0.2-20:1. The composition is advantageous in that the composition has reasonable components, good insecticidal effects and low drug-using cost; activity and insecticidal effects of the composition are not simply addition of activity of each component but have remarkable synergy effects; the composition has high rapid-acting property and long effect persistence; the composition slows down generation of resistance; and the composition is good to crop safety, and meets safety requirements of pesticide preparations. The control efficiency of the composition for citrus red mites, apple red mites, and mites on cotton crops reaches 86.65%-96.38%.
Description
Patent application of the present invention is that invention and created name is a kind of Pesticidal combination that contains Bifenazate, and application number is 200910205340.7, and the applying date is dividing an application of 20091010 patent applications.
Technical field
The present invention relates to a kind of Pesticidal combination, particularly contain Bifenazate as first active component a kind of comprising, fenbutatin oxide or four mite piperazines belong to technical field of compounded pesticide as 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 5 000mg/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 preventing and treating the 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, with the Bifenazate be the pesticidal preparations of effective ingredient based on 480 grams per liter Bifenazate suspending agents, 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.

Table 3 for behind the medicine the 7th day the time each residential quarter 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, 20% Bifenazate clofentezine suspension agent is respectively handled differences with other for 1500 times, 2000 times and is all reached utmost point significance level, 2500 times of 20% Bifenazate clofentezine suspension agents and contrast medicament 480g/ rise 3000 times two of Bifenazate suspending agent to handle differences not remarkable, and two handle and all rise 6000 times of processing of clofentezine suspension agent differences with 500g/ and reach utmost point significance level.
Field trial shows: 20% Bifenazate clofentezine suspension agent has than remarkable prevention effect citrus red mite, its 1500 times, 2000 times control efficiency obviously is better than contrasting the control efficiency that medicament 480g/ rises 3000 times of Bifenazate suspending agents, 6000 times of 50% clofentezine suspension agents, its 2500 times with 480g/ to rise the control efficiency of 3000 times of Bifenazate suspending agents suitable substantially, after result of the test shows that Bifenazate and four mite piperazines are mixed, obviously improved the control efficiency to citrus red mite, greatly reduce dosage, to mandarin tree growth safety.
Biological Examples 4: control cotton red spider field trial
Carried out the field control effectiveness test of the 20% Bifenazate clofentezine suspension agent control cotton red spider of FORMULATION EXAMPLE 8 in the solid town of Shaanxi Province's Weinan City, verified that this medicament is to the control efficiency of cotton red spider, effective dose and to the safety of cotton.Trial crops is cotton, controlling object cotton red spider (Tetranychuscinnabarinus (Boisduval)).Test medicine and dosage are 1500 times of 20% Bifenazate clofentezine suspension agents, 2000 times, 2500 times, and 480g/ rises 3000 times of Bifenazate suspending agents, and 500g/ rises 6000 times of clofentezine suspension agents, adopts conventional spray-on process.Investigation insect population radix before the dispenser, 3d, 7d, 14d, 30d investigate residual borer population alive respectively behind the medicine, 5 samplings in every residential quarter during investigation, fix the investigation of 2 strain cottons at every, every strain fixedly upper blade has 5, the two spotted spider mite number on the investigation fixed blade, record mite number alive carries out the control efficiency statistics.

Table 4 for behind the medicine the 7th day the time each residential quarter 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, 1500 times, 2000 times processing of 20% Bifenazate clofentezine suspension agent and other are respectively handled differences and are all reached utmost point significance level, and it is not remarkable that its 2500 times of processing and contrast medicament 480g/ rise 3000 times of processing of Bifenazate suspending agent differences; 2500 times of 20% Bifenazate clofentezine suspension agents, 480g/ rise 3000 times of Bifenazate suspending agents and handle and all rise 6000 times of processing of clofentezine suspension agent differences with 500g/ and reach utmost point significance level.
Field trial shows: 20% Bifenazate clofentezine suspension agent has remarkable prevention effect to cotton red spider, and its 1500 times, 2000 times control efficiency obviously is better than contrasting medicament 480g/ and rises the control efficiency that 3000 times of Bifenazate suspending agents, 500g/ rise 6000 times of clofentezine suspension agents.Result of the test shows: after Bifenazate and four mite piperazines are mixed, obviously improved quick-acting and lasting period to cotton red spider, reduced dosage and drug cost, to cotton growth safety.
In sum, composition of the present invention is to adopt two kinds of active component compound schemes, its activity and miticidal effect are not the simple superposition of each composition activity, compare with existing unitary agent, except having significant miticidal effect, and significant synergistic effect arranged, quick-acting height, lasting effect are long, slow down the generation of resistance, and be good to crop safety, dosage reduces, and meets the security requirement of pesticidal preparations.
