Abstract
The invention relates to an insecticide composition containing spinosad and neonicotinoid insecticide and the application thereof. The composition comprises spinosad which is used as a first active ingredient and neonicotinoid insecticide which is used as a second active ingredient; wherein the second active ingredient is selected from imidacloprid or thiamethoxam; the weight ratio between the first active ingredient and the second active ingredient is (0.01-200):1, preferably, (0.05-20) :1. The composition has the advantages that the components are reasonable, the disinsection effect is good, the drug consumption cost is low, the activity and the disinsection effect have remarkable synergistic action but not simple superposition of the activities of all the components, resistance can not be generated, the level of residue of the preparation is low, no pollution can be caused to crops, the security is good, and thereby the composition conforms to the security requirement for pesticide preparations. The composition has 87.11 to 96.04 percent of prevention and control effects on thysanoptera pests, for example, common thrips, and homoptera pests such as lice and aphides.
Description
Technical field
The present invention relates to a kind of Recompounded pesticide, contain the Pesticidal combination of multiple killing teichomycin, particularly a kind of Pesticidal combination and application thereof that comprises multiple killing teichomycin and anabasine insecticide belongs to technical field of compounded pesticide.
Background technology
Multiple killing teichomycin has another name called pleocidin, english common name Spinosad, the product of practicability is the mixture of spinosynA and spinosynB, so be called spinosad, chemical molecular formula SpinosynA:R1=N (CH3) 2, R2=H, R3=CH3, Spinosyn D:R1=N (CH3) 2, R2=CH3, R3=CH3.Pleocidin can sustained activation target insect acetylcholine nicotine receptor, insect is had tag fast and stomach poison function, and blade is had stronger osmosis, can kill subepidermal insect, and the longevity of residure is longer, no systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some measures the pest species of food blade greatly in coleoptera and the orthoptera, safer to the predator insect, plant safety is not had poisoning.Be suitable for using on vegetables, fruit tree, gardening, the crops.But in the practice process, use multiple killing teichomycin list agent quick-acting relatively poor separately, insect easily produces resistance.

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, 1000 times of 6% multiple killing teichomycin Imidacloprid missible oil are not remarkable with 5000 times of processing of 70% imidacloprid water dispersible granule differences, and the two all reaches utmost point significance level with 1500 times, 2000 times processing of 6% multiple killing teichomycin Imidacloprid missible oil differences.
Field trial shows: 6% multiple killing teichomycin imidacloprid water dispersible granule has remarkable prevention effect to apple aphid, 1000 times of 6% multiple killing teichomycin Imidacloprid missible oil are compared for 5000 times with the 70% imidacloprid water dispersible granule list agent of contrast medicament, two effect of chemical control are suitable substantially, after test shows that multiple killing teichomycin and Imidacloprid are mixed, obviously improved control efficiency to wooly aphis, greatly reduce dosage and drug cost, to apple safety.
Biological Examples 3: control water rice hopper field trial
We have carried out 21% multiple killing teichomycin thiophene worm piperazine water dispersible granules on July 30th, 2007 and have prevented and treated the field control effectiveness test of rice hoppers in Ban Dun village, Jiaxing City, Zhejiang Province Dong Peng township, verified that this medicament reaches the safety to paddy rice to rice hoppers control efficiency, effective dose.Trial crops is a paddy rice, and kind is excellent 9308 for association, the controlling object rice hoppers.Adopt conventional spray-on process, respectively at respectively carrying out once residual borer population investigation before the medicine, behind the medicine in 2 days, 7 days, 14 days.Take the random sampling of balance great-jump-forward, 10 every 2 clumps of every sub-districts (totally 20 clumps), with basin bat method record rice fulgorid (comprising small brown rice planthopper, brown planthopper and white-backed planthopper) borer population, by before every clump of medicine, the borer population calculation correction preventive effect behind the medicine, and carry out the significance of difference and measure.2,7,14 days observation paddy growth situations behind medicine are estimated reagent agent and are had or not poisoning to produce to paddy rice simultaneously.
