Gained dryness powder is Chinese herbal medicine pesticide, and package encapsulation preserves.
The present invention has following advantageous effect：
(1) Chinese herbal medicine pesticide of the invention has the advantages that efficient, less toxic, pollution-free and toxic side effect, acts on agriculture
The prevention and control of plant diseases, pest control of crop, noresidue is environmentally protective, ensures health, promotes the development of novel ecological agricultural；
(2) it can be detached from tripterygium wilfordii with isolated 9 Pesticidal compounds added with tripterygium wilfordii in raw material of the present invention
The insecticide active substance gone out belongs to entirely different several compounds, and the mode of action and the mechanism of action are unique, action spectrum less phase
Together, there is broader market in production practices；Its insecticidal constituent has the various pests such as diamondback moth, cabbage caterpillar, aphid
Significantly tag, the effect of stomach toxicity, food refusal and inner sucting killing insect, the main function position of insecticidal constituent is midgut epithelial cells plasma membrane and interior
Film；
(3) kuh-seng is added in raw material of the present invention, matrine can be extracted in kuh-seng, matrine is final under the Nature
Carbon dioxide and water can be resolved into, it is harmless to environmental and human health impacts, and because the ingredient in matrine is not single,
But a variety of chemical constitution substances combine, and complement each other, play a role jointly, it is made not easily lead to nuisance and is developed immunity to drugs；
(4) chemical stability of Chinese herbal medicine pesticide can be increased added with emulsifier, emulsifier in raw material of the present invention, no
Can due to storage time intestines decomposition failure, when herbal sprinkling can reduce the loss of liquid, improve active ingredient dispersion degree and
Active ingredient so as to reach the control effect for giving full play to medicament, and will not increase the deposition and deposition fraction of target body
Active compound is to the toxicity of mammal or reduces virulence to harmful substance, environmentally safe；
(5) raw material selected by insecticide of the present invention is Chinese herbal medicine series, is easy to degrade in the environment, and no environment is dirty
The worry of stain residual hazard, to people, animal, Environmental security, due to its chemical property complexity, pest is not likely to produce drug resistance, both meets agriculture
The direction of medicine development is also adapted to the good hope that people require " pesticide greening purification ".
