Abstract

The invention discloses an efficient insectofungicide containing beauveria bassiana and pyraclostrobin. Active ingredients of the product are beauveria bassiana and pyraclostrobin. Mass content of beauveria bassiana is 10-30%, and mass content of pyraclostrobin is 10-25%. The dosage form of the insectofungicide is an oil-suspended injection, wettable powder or water dispersible granules. The insectofungicide can be used for controlling plant diseases and insect pests for crops, and has an effect of treating plant diseases and insect pests for various crops, including main vegetable pests whitefly and diamondback moth and important vegetable diseases powdery mildew, downy mildew, late blight, early blight, anthracnose, etc. What's more important is that pyraclostrobin can enhance virulence of beauveria bassiana to diamondback moth.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an insecticidal and bactericidal composition, in particular to a high-efficiency insecticidal and bactericidal agent containing Beauveria bassiana and pyraclostrobin, which is mainly used for preventing and treating powdery mildew, downy mildew and late blight , Early blight, anthracnose, whitefly, diamondback moth and other pests and diseases. Background technique [0002] Beauveria bassiana is currently the most researched and applied entomopathogenic fungus in the world. It has the characteristics of strong pathogenicity, wide insecticidal spectrum, no killing of natural enemies, and ecological safety to humans and animals. For a long time, Beauveria bassiana has been widely used at home and abroad to control various agricultural and forestry pests such as grubs, whiteflies, leaf beetles, locusts, tea leafhoppers, corn borers, and pine caterpillars, and has achieved remarkabl...
