Abstract

The invention discloses a bactericidal composition and belongs to the technical field of pesticides. The bactericidal composition contains Tianmingjing lactone and nonyl copper, wherein the weight ratio of Tianmingjing lactone and nonyl copper is 1:80-80:1, and the fungicidal composition can be used to prevent common Plant fungal diseases, against corn big spot, privet brown spot, apple scab, apple ring spot, cherry brown rot, cucumber downy mildew, mint spot blight, tomato scab, tomato gray mold, Wheat head blight, wheat stripe rust, wheat stem rust, pepper phytophthora, etc. all have good control effects, and the effect is significantly higher than that of active ingredients alone, and delays the emergence of bacterial resistance, prolongs the duration of efficacy, and is effective for breastfeeding. animal safety.

Description

technical field [0001] The invention belongs to the field of pesticide fungicides, and in particular relates to a fungicidal composition containing astragalactone and nonylcopper and its application in preventing and treating fungal diseases of plants. Background technique [0002] Carabrone is a sesquiterpene lactone compound, which can be extracted from the roots, stems and leaves of the Asteraceae plant. Preliminary studies have shown that it has the functions of eliminating phlegm, clearing away heat, It has medicinal activities such as hemostasis and detoxification, and it also has insecticidal and bactericidal activities in agriculture. It has a good control effect on common plant diseases such as wheat powdery mildew and wheat take-all. Tianmingjing lactone is a plant-derived pesticide. Although it has the advantages of low toxicity, environmental safety and long-lasting effect, it also has the disadvantages of slow effect and high price. [0003] Nonylcopper is an o...
