Abstract

The invention belongs to the technical field of pesticide, and particularly relates to a biological fungicide for preventing and treating botrytis cinerea and a preparation method thereof. The biological fungicide for preventing and treating botrytis cinerea is prepared from, by weight, 5-10 parts of cocklebur fruits, 8-12 parts of folium syringae, 6-10 parts of camphor tree leaves, 6-13 parts of folium eucalypti, 7-13 parts of cortex cinnamomi, 10-15 parts of cymbopogon citrates, 5-10 parts of vetiveria zizanioides, 5-15 parts of emulgator, 0-10 parts of synergist and 120-200 parts of organic solvent. The biological fungicide is stable in drug property, the expiration date can reach two years, the biological fungicide is free of residues, easy to degrade, harmless to people and livestock, remarkable in antibacterial effect and capable of applied and popularized, and the inhabitation ratio on botrytis cinerea hypha can reach 90% or above.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a biological fungicide for preventing and treating tomato gray mold and a preparation method thereof. Background technique [0002] Botrytis cinerea is a worldwide important disease, which mainly causes fruit rot and poses a great threat to tomato production in protected areas. In terms of prevention and control, benzimidazole and dimethylimide fungicides are mostly used for prevention and control, but continuous use has caused the bacteria to develop drug resistance, the control effect has decreased year by year, and it has also caused pollution to the environment. [0003] Chinese patent CN102805115B discloses a botanical natural fungicide for tomato cinerea. The raw materials of the fungicide include garlic essential oil, plant essential oil mixture, organic solvent, surfactant, and water. In the present invention, garlic essential oil is used as the main bacte...
