Abstract

The invention discloses a botanical pesticide for treating anthracnose. The botanical pesticide is made by compounding a composition including eugenol, garlic polysaccharide and a smoke tree extract with a microemulsion or aqueous emulsion made from auxiliary agents. The composition includes, by mass percentage, 20-40% of eugenol, 30-40% of garlic polysaccharide and 20-50% of a smoke tree extract. The botanical pesticide takes eugenol as a main active component, takes garlic polysaccharide and the smoke tree extract as synergistic components, and is suitable for spraying different fields, such as a land and greenhouse soil. The botanical pesticide has a good treatment effect on anthracnose, and pathogenic bacteria are not prone to produce drug resistance, so that the botanical pesticide has great economic, social and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a botanical pesticide for preventing and treating plant anthracnose and its application. Background technique [0002] Anthracnose is the main disease on melons, fruits, vegetables, and tea leaves. It has a wide range of damage and is difficult to control. At present, the agents used to prevent and control anthrax are mainly chemical fungicides. However, the long-term use of a large number of chemical drugs has led to the emergence of problems such as drug resistance, environmental pollution, and harm to human health; The use of many chemical pesticides has had to be restricted. Searching for bactericidal active substances from the treasure house of natural resources is becoming an important way and research hotspot for the creation of new bactericides. Especially through the scientific compounding of multiple ingredients, the effect of the plant-derived fungicid...
