The invention relates to an insecticide composition containing benclothiaz and pleocidin. The insecticide composition containing benclothiaz and pleocidin is characterized in that active components are benclothiaz and pleocidin and the balance is auxiliary ingredients used for preparing a pesticide formulation, wherein the ratio of benclothiaz to pleocidin in parts by weight is (1-30) to (0.1-10), the insecticide composition can be prepared into pesticide formulations such as wettable powder, a suspending agent, soluble liquor, emulsion in water and water dispersible granules, and the total parts by weight of benclothiaz and pleocidin active components in the formulation accounts for 1-30% of the total parts by weight of the formulation. The insecticide composition contains two effective active components, namely benclothiaz and pleocidin, has an obvious synergistic effect and can be prepared into a preparation applicable to agricultural application, the insecticidal spectrum is expanded, the usage amount of pesticide is reduced, the control efficiency is improved, less residue is produced, the lasting period is long, and delay of production of drug resistance of pests and environmental protection are facilitated.
Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing benclothiaz and pleocidin.
Background technology
Benclothiaz is considered to nematocide usually, thinks the highest to nematode activity, and since compound structure is announced, seldom see the activity research to other field or other insects, the more rare application in agriculture chemical compounding field, its chemical structural formula is as follows:
。
Pleocidin, having another name called multiple killing teichomycin (Spinosad) is a kind of macrolides Nuisanceless high-efficient biological insecticides extracted in sugared many born of the same parents bacterium (Saccharopolysporaspinosa) zymotic fluid of thorn.The mode of action of pleocidin is novel, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Insect can be made to benumb rapidly, paralyse, finally cause death.Its desinsection speed can compare favourably with chemical pesticide.Safety is high, and is the biological insecticides of low toxicity, efficient, low-residual without cross resistance with current common insecticide, and existing efficient insecticidal properties, has again the characteristic to having beneficial insect and mammalian safe, the most applicable pollution-free vegetable, Production of fruit application.It is the insecticide of a kind of low toxicity, efficient, wide spectrum.But pleocidin is through extensive application in recent years, and insecticidal effect obviously declines, have a strong impact on the application prospect of this single dose.
The insecticide that Long-Time Service is single or bactericide, insect or germ are easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field are more single.The different mechanism of action and without the insecticide of cross resistance and bactericide rational mixture by a certain percentage, crop disease prevention effect can be improved, minimizing dosage, residual few, reduce environmental pollution, effectively reducing the pesticide resistance of crop, is the study hotspot of current medium and small research and development institution.

Field experiment: field experiment control wild cabbage damage by disease and insect
(1) test method
Test sprays medicine 1 time altogether, and the dispenser date is in June.Now wild cabbage not yet balling, diamondback moth larvae major part was in for 2 ~ 3 length of times, and during spray medicine, weather is cloudy calm, and with sharp agriculture board level pressure knapsack hand sprayer to each process even spraying, leave dual sides all requires to be sprayed with effect liquid, every community liquid 2L.
Investigate each community and fix 15 strain wild cabbages as investigation strain, record the larva quantity on whole blade, before spraying medicine, investigate insect population radix, respectively 3,7 days and investigation in 10 days borer population alive after spray medicine.This test investigates 3 times altogether.
(2) drug effect computational methods
Live before Revision insect recluced rate (%)=(borer population of living after borer population one dispenser of living before dispenser)/dispenser borer population * l00.
Preventive effect (%)=(treatment region Revision insect recluced rate-check plot Revision insect recluced rate)/(100-check plot Revision insect recluced rate) * 100.
(3) poisoning investigation method
After dispenser, continuous 10d estimates medicament does not have poisoning to produce to crop, wild cabbage well-grown.
(4) field control effectiveness test result of the test
Table 2 treatment agent control diamond-back moth field control effectiveness test result
As can be seen from Table 2, the successful of 14%benclothiaz+1.5% pleocidin control diamond-back moth is better than 5% pleocidin EC and contrasts single dose, 14%benclothiaz+1.5% pleocidin insecticidal effect of 7 days after medicine is respectively 93.72%, 93.55% and 94.38%, after medicine, the insecticidal effect of 10 days is respectively 92.61%, 93.55% and 96.63%, and insecticidal effect increases progressively along with the increase of consumption.In addition within the scope of test dose, plant growth is normal, and the poisoning phenomenon to wild cabbage does not all appear in each treatment agent, illustrates that it is safe to wild cabbage.
In addition within the scope of test dose, plant growth is normal, and the poisoning phenomenon to cucumber does not all appear in each treatment agent, illustrates that it is safe to cucumber.
