Compound plant source nano pesticide of the invention, has the advantage that.
1) nontoxic, pollution-free, protection environment
Compared with chemical pesticide ingredient, compound plant source nano pesticide is free of any chemical synthesis substance, and effective component is
The insecticide active substance being extracted from plants, the degradable, noresidue, pollution-free in water body, soil and atmosphere, belong to safety,
Environmentally friendly product.Using the hydrolysis of complex enzyme agent, the active insecticidal components in plant cell is allowed to be able to be easy to release,
Cooperate water-soluble nano montmorillonite powder to load botanical pesticide particle, enhances the dispersibility of botanical pesticide particle in a liquid
And dissolution efficiency prevents solvent contamination with water directly instead of organic solvent containing benzene.
2) application times are reduced, agriculture production cost is reduced
Compared with existing plant source kind pesticide, botanical pesticide particle is loaded using nano montmorillonite powder, it not only can be with
Improve the problem of botanical pesticide is easy photodissociation, and the slow release of drug, extends the lasting period.Tong Time nano montmorillonite powder
Ultra micron effect is easily adhered over the paddle, can not only be reduced blade face pesticide and be fallen off, and the utilization rate of pesticide is improved, and
And nano montmorillonite powder has expelling parasite, bactericidal effect, effectively reduces pesticide because of the meeting slight electric current of sustained release after sunlight irradiation
Application times, to reduce agriculture production cost.
3) it is not easy that pest is made to develop drug resistance
Chemical pesticide, existing single plant source kind pesticide are compared, is contained in compound plant source nano pesticide component several
Effective insecticidal constituent has synergistic effect, can expand the insecticidal spectrum of pesticide finished product, improves the drug effect of pesticide finished product, effectively prevents
Various agricultural pest, selectivity is strong, and to non-target organism safety, pest is not likely to produce drug resistance, and long-time service can be effectively controlled
Pest population density and size.
4) medicine fertilizer economic benefits and social benefits
Compared with comparing chemical pesticide, compound plant source nano pesticide not only has desinsection, bactericidal activity, can also promote
Plant growth.Contain the substances such as a large amount of organic acid, phenols, minerals and hormone, these objects in compound plant source nano pesticide
The growth and development of crop is not only adjusted in matter, also can induce crop and generates disease resistance or resistance, has medicine fertilizer double effects, right
Crop promotes volume increase, improving quality to have remarkable effect.
