Sterilizing compound

Abstract

The invention relates to a sterilizing compound which comprises the effective components of fluopicolide and propineb. The weight ratio of fluopicolide and propineb is (1:50)-(50:1). The compound can be prepared into suspensions, wettable powder and water dispersible granules and is mainly used for preventing and treating vegetable downy mildew. The sterilizing compound is remarkable in sterilizing effect, long in lasting period and safe to crops, and has remarkable synergistic effect.

Description

[0001] Technical Field The present invention belongs to the field of pesticide technology and has a synergistic fungicidal composition, the active ingredients of which are fluopyram and propineb. Background technique

[0002] Fluopicolide is a new type of fungicide launched by Bayer Crop Science Company in Germany, which can effectively protect and control oomycete vegetable diseases. The product has excellent system conductivity and strong thin-layer penetration, and has a good inhibitory effect on the main forms of pathogenic bacteria, and can provide comprehensive and long-lasting protection for new leaves, stems, tubers, and young fruits. Because the agent can be quickly absorbed through the leaves, it is resistant to rain erosion, providing a reliable guarantee for the disease prevention of vegetables in the rainy season. This product is mainly used on various vegetables and grape crops. It has excellent control effect on common oomycete diseases such as downy mildew, bli...
