Description

A kind of application technology in disinsection aqueous emulsion for paclobutrazol
Technical field
The invention belongs to environmental-protecting chemical pesticides application production field, it is related to a kind of paclobutrazol answering in disinsection aqueous emulsion Use technology.
Background technology
Rationally scientifically can improve prevention effect using pesticide, delay harmful organism to develop immunity to drugs or expand to use model Enclose simultaneous control different types of harmful organism, save manpower and dosage, reduces cost, improve drug effect, reduce toxicity, it is right to strengthen The safety of people, animal.
The equipment that various pesticide are applied has its specific purposes and performance, and during dispenser, liquid preparation sprays, powder Dust, granule spreads fertilizer over the fields, poison bait puts into performance, the feature being both needed to consider the apparatus and equipment using, and could play it well Due effect, makes medicament uniformly be distributed in crop or harmful organism surface thoughtfully, acquirement science, efficiently prevents and treats result.
Using controlling object must be recognized before pesticide and grasps the suitable pesticide species of selection, with reference to various places plant protection Books that department is write, handbook, prevent from misapplying pesticide, reach the ideal effect of dispenser to the ill.
Pesticide is also the important means that the mankind prevent and treat agricultural pest and disease damage, and chemical pesticide plays to the increasing both production and income ensureing agricultural Very important effect, but the use of pesticide, while Ensuring Food Safety produces, also bring residual, pollution etc. Serial environment and social problem.
Pesticide is the special chemicals of a class, and it can prevent and treat agricultural pest and disease damage, also can produce harm to people and animals.Therefore, The use of pesticide, on the one hand brings benefit to the mankind, and on the other hand also gives people class and relies the environment according to existence to bring harm, according to related report Road, pesticide utilization rate is generally 10%, and about 90% residual in the environment, causes the pollution to environment.The pesticide scattering and disappearing in a large number It evaporate in the air, flow in water body, sedimentation is gathered in soil, pollute farming animals fishing fruit product, and by the enrichment of food chain Human body is transferred in effect, produces harm to human body.Therefore, develop safe efficient environmental protection, extend the lasting period, mitigate poisoning, fall Low pesticide residual in the environment, the novel form preparation of the range of application increasing pesticide have become the development side of pesticide in future dosage form One of to.
, as a kind of novel environment friendly dosage form, in terms of extending the pesticide lasting period, contribution is remarkable for aqueous emulsion, but its internal interpolation Compositions, method is different, and on market, existing aqueous emulsion seldom has formula or the composition adding physics stabilizer.And the present invention mainly with Paclobutrazol makes water and milk system more stable for physically stable agent cooperation conventional chemical stabilizer, and its property has that raw material is nontoxic, holds The effect phase is good, physical and chemical stability is high and the advantages of good biocompatibility.
But the duration of each product of aqueous emulsion that existing market is sold is relatively short, cause the frequent medication of peasant simultaneously constantly Improve dosing, much area all causes drug-fast generation, and the lasting period extending this medicament for this becomes urgently to be resolved hurrily Problem.Additionally, the current Water emulsion using is still with aromatic hydrocarbon as primary solvent, due to using substantial amounts of mineral soil with have Machine solvent, not only consumes substantial amounts of fossil resources, and environment be also result in very big pressure.Replace aromatic hydrocarbon with environmentally friendly solvent molten After agent, its stability not only can be improved, extend the lasting period, reduce application times and amount of application, can also be mitigated it to environment With the harmful effect of agricultural product, thus improve medication safety.
The defect existing for existing method for producing aqueous emulsion above and Related product, the application purpose is to develop special In insecticide and a kind of new aqueous emulsion product of high-efficiency environment friendly of crop yield can be improved, above aqueous emulsion system both can be solved The safety issue of standby process, can keep the exclusive feature of aqueous emulsion product again.This aqueous emulsion product is removed has prevention and control insect pest Can be outer, also by adding synergist and plant growth regulator, significantly improve drug effect, after aqueous emulsion product of the present invention, The drug effect lasting period is long, and yield lifting substantially, thus decreasing the persistently administration pollution to environment for the chemical pesticide, is more beneficial for reducing Pesticide residues on crop.And the product being exclusively used in pest control is more easy to and Fertilizer combination, mixture is simple, uniformly, can substantially contract During casual labourer, improve work efficiency, increase drug effect.
Content of the invention
