Description
Technical field
The invention belongs to Chinese medicine compound technical field, be specifically related to a kind of Chinese medicinal plant bactericidal composition, also relate to
A kind of preparation method of Chinese medicinal plant bactericidal composition.
Background technology
China is large agricultural country, the long-term occurring area of crop diseases and pest crop smothering about 400,000,000 m2, need to produce every year and use agriculture
Medicine 800,000 tons, pesticide has become indispensable factor in agricultural production.Being widely used of pesticide, although production development is played
Important function, but also occur in that such as insect pest, disease resistance problems, to the pollution of environment and in agricultural and animal products residual
Stay and accumulation problem, injure natural enemy, destroy balance of nature, cause pest resurgence problem etc..This development to novel pesticide
Propose higher requirement.Since 21 century, along with people advocate nature, protection environment, pay close attention to food safety
Cry the most surging, harmless boilogical pesticide industry and field of biological control research obtain rare opportunity to develop.
Facing to the raising of people's living standard, vegetable is increasingly paid attention to by people safely with food.But it is economical sharp
Benefit orders about being excessively used of chemical pesticide, and vegetable safety exists bigger hidden danger.Must there be some noresidues, high security, height
The pesticide of effect replaces traditional high poison, high residue, the chemical synthetic pesticide that is harmful to humans and animals.Going out of China's Vegetable product
Mouthful be just on the hazard because pesticide exceeds standard and challenge, use plant pesticide replace synthesis chemical pesticide, it can be ensured that victual without
Pesticide residues and pollution.Currently also having some plant pesticides, but formula is unreasonable, effect is not ideal, or is not suitable for industrialization
Produce, a kind of environmental protection of market in urgent need, the plant pesticide of efficient, applicable large-scale production.
