Description
Technical field
The invention belongs to biological pesticide technical field, relate to a kind of oily composition, its preparation method, and
Preparation purposes in the biological pesticide of pest control.
Background technology
China is a large agricultural country, and agricultural occupies important fundamental position in Chinese national economy.As generation
Country most populous in boundary, China produces the grain accounting for the world 25% with the arable land in the not enough world 10%,
Support the population in the Liao Zhan world more than 22%.But, diseases and pests of agronomic crop Que Shi China present in agricultural production
One of major casualty, have that kind is many, greatly and outburst often such as is caused disaster at the feature, often to state of China in impact
People's economy (particularly agricultural production) causes heavy losses.
The domestic common diseases and pests of agronomic crop of China includes powdery mildew (main harm Semen Tritici aestivi, Fructus Hordei Vulgaris, rye (Secale cereale L.), swallow
Wheat), wheat rust (main harm Semen Tritici aestivi, Fructus Hordei Vulgaris), the sheath and culm blight of rice (main harm Oryza sativa L., Fructus Hordei Vulgaris, little
Wheat, Sorghum vulgare Pers., Semen Maydis, foxtail millet), rice blast (main harm Oryza sativa L.), gibberella zeaze petch of wheat and barley (main harm Semen Tritici aestivi,
Fructus Hordei Vulgaris), planthopper (main harm Oryza sativa L., Semen Tritici aestivi, Semen Maydis), Pyrausta nubilalis (Hubern). (main harm Semen Maydis, Sorghum vulgare Pers.,
Helianthi), bollworm (main harm Cotton Gossypii), cotten aphid (main harm Cotton Gossypii), wheat aphid (main harm
Semen Tritici aestivi, Semen Maydis, Sorghum vulgare Pers.), wheat tetranychid (main harm Semen Tritici aestivi, Fructus Hordei Vulgaris, Brassica campestris L, Cotton Gossypii), locust (main
Semen Tritici aestivi to be endangered, Semen Maydis, Sorghum vulgare Pers., Oryza sativa L.) etc., these pest and disease damages have had a strong impact on China's agricultural production.
Currently, most domestic agricultural product production commercial city uses chemical pesticide to control and eliminate to be caused by harmful bacteria
Pest and disease damage, but the use of chemical pesticide can eliminate probiotics simultaneously, destroys original ecological balance, and
And the Drug resistance of harmful bacteria strengthens day by day, then pesticide variety is more with the most, and dosage more with the biggest, makes soil
Acidifying, alkalization, cause soil to harden, cause environmental pollution.The more important thing is, after using chemical pesticide,
All can there be pesticide residues on the surface of major part agricultural product, directly affects the healthy of consumers in general.There is data
Display, China has become the big pesticide producing of the first in the world and has used state, the average use of chemical pesticide in unit are
Measuring higher 2.5～5.0 times than world average dose, China suffers the crop area of pesticide residual contamination about to reach 800 every year
Ten thousand hectares, wherein the ratio of severe contamination is up to 40%, and the agricultural product such as vegetable, Oryza sativa L., fruit tree and Folium Camelliae sinensis
Pesticide Residue is particularly acute.
In recent years, biological pesticide is being widelyd popularize and used in countries in the world all, and China is long-term science and technology in 2015
Biological pesticide is also classified as key research projects by planning.But, natural enemy insect is the most not yet become note by acceptance
Volume product, strengthens biological pesticide new-product development, accelerates biological pesticide industry development speed, increases biological pesticide
The market share, meets the need of the prevention and control of plant diseases, pest control in China's non-polluted farm product, pollution-free food and organic foodstuff production
Want, alleviate the problem of environmental pollution that brings of pesticide residues oneself become scientific and technological circle of China, problem that industrial circle is paid close attention to.
Summary of the invention
