Description
Technical field
The present invention relates to control of agricultural pest field, specifically, relate to a kind of insecticides and application thereof.
Background technology
Cotton bollworm (Helicoverpaarmigera, H ü bner) belongs to Lepidoptera Noctuidae, and its feeding habits are assorted, Ji Zhuduo, have a very wide distribution, and has stronger fertility and ability of migrating, belongs to the crushing insect in field-crop.The control of cotton bollworm in the past mainly relies on chemical agent, and along with the plantation of genetically modified crops, the harm of cotton bollworm obtains effective control, but along with the prolongation of implantation time and using of chemical pesticide year after year, the resistance of cotton bollworm to Multiple Pesticides raises year by year.
Gamma cyhalothrin (Lambda-Cyhalothrin), 3-(2-chloro-3,3,3-trifluoro-propenyl)-2,2-dimethyl cyclopropane carboxylic acid alpha-cyano-3-phenoxybenzyl ester, has another name called cyhalothrin, Cyhalothrin, is a kind of efficient, wide spectrum, quick-acting pyrethroid Insecticidal and acaricidal agents, to various pests such as Lepidoptera, coleoptera and Semipteras, all there is good control efficiency, also can be used to prevent and treat multiple earth's surface and public health insect.
Gamma cyhalothrin acts on the nervous system of insect, and insect is overexcited, paralysis and dead.Compared with other pyrethroid insecticideses, this medicine insecticidal spectrum is wider, insecticidal activity is higher, drug effect more rapidly and there is strong osmosis, make that resistance of rainwater washing against ability is stronger, the lasting period extend.
Gamma cyhalothrin becomes one of insecticide be most widely used because having the features such as desinsection broad spectrum activity, relative safety, but due in recent years to present situation aggravations such as the undue dependence of this agricultural chemicals and unreasonable uses, thus accelerate insect produces resistance process to gamma cyhalothrin.Especially, after Bt cotton seed is planted, cotton field sucking pest is caused harm as cotton leaf bug, aphid, two spotted spider mite etc. and is increased the weight of, and gamma cyhalothrin and complex preparation are rising year by year in cotton field dosage.Monitoring result shows, the resistance level of northern China major part cotton region cotton bollworm to gamma cyhalothrin is higher, and have the trend of rising, therefore urgently adopt an effective measure service life of extending agricultural chemicals or avoid the generation of resistanc pest, research and development gamma cyhalothrin chrysanthemum ester synergist has good actual production value.
Tea Saponin (Teasaponin) has another name called tea saponin, and the mixture of tea saponin to be the class formation contained in plant of theaceae be Triterpenoids sapogenins saponins is a kind of natural non-ionic surface active agent of good performance.In agricultural chemicals, add Tea Saponin, obviously can improve the physicochemical property of pesticide solution, improve medicament at adhesive force that is biological or plant surface, contribute to the performance of drug effect, thus play synergistic effect, reduce the toxicity to environment and pollution.
Tea Saponin has certain tagging and avoidance effect to lepidopterous insects, but in actual production, because the Tea Saponin lasting period is short, is easy to decompose and working concentration is higher, therefore alone Tea Saponin poor effect.Although Tea Saponin is lower as the direct insecticidal activity of a kind of insecticide to insect, if but add in agricultural chemicals, but obviously can improve the physicochemical property of pesticide solution and improve medicament at adhesive force that is biological or plant surface, in addition it easily degrades in natural conditions, residual life, is short, environmentally friendly, to person poultry safety, therefore it can be used as a kind of pesticide synergistic agent to use, have broad application prospects.
Tea Saponin adds in the agricultural chemicals such as Rogor, rotenone, Bristol gram respectively, and the virulence of turnip aphid, oranges and tangerines being grabbed entirely to mite significantly improves.Therefore, Tea Saponin is added in agricultural chemicals as synergist and uses, mainly by reducing the surface tension of pesticide solution, improving liquid sticking together and wettability effect at plant surface, improving the effective precipitation of liquid, thus play the effect improving drug effect.
Summary of the invention
The object of this invention is to provide a kind of novel insecticides and application thereof.
In order to realize the object of the invention, a kind of insecticides of the present invention, described composition adds Tea Saponin in Liquid Insecticides, thus effectively reduce the amount of application of agricultural chemicals, increases gamma cyhalothrin to the control efficiency of cotton bollworm simultaneously.The active ingredient of described insecticide is made up of according to mass ratio 0.7-7.5:3.3-6.7 cyhalothrin and Tea Saponin.
Preferably, the mass ratio of cyhalothrin and Tea Saponin is 5-7.5:3.3-4.
More preferably, the mass ratio of cyhalothrin and Tea Saponin is 7.5:4.
Insecticides provided by the invention can be the formulations such as missible oil, granule, wetting powder, suspending agent, water dispersible granules or microemulsion.
The present invention also provides the application of described insecticides in control cotton bollworm.
The present invention has the following advantages:
(1) gamma cyhalothrin is as wide, the comparatively safe insecticide of a kind of insecticidal spectrum, but long-term field is used, cotton bollworm is rising trend to its pesticide resistance, and insecticides adjuvant (synergist)--the interpolation of Tea Saponin obviously can improve physics or the chemical property of agricultural chemicals, play drug effect to greatest extent and reduce amount of application, contributing to the insecticidal effect improving gamma cyhalothrin.
(2) necessarily tag and avoidance effect although Tea Saponin has lepidoptera pest, it is used alone, and concentration is higher, and preventive effect is lower, and actual value is less.A certain proportion of Tea Saponin adds in gamma cyhalothrin liquid by the present invention, the working concentration of gamma cyhalothrin and Tea Saponin can not only be reduced, reduce drug cost, improve the control efficiency to cotton bollworm, the toxicity to environment and the residue of pesticide of minimizing on crop can also be reduced.
