Abstract

The invention discloses a bactericidal composition containing coumoxystrobin and tetramycin, and applications thereof. The bactericidal composition contains main effective components coumoxystrobin and tetramycin at a mass ratio of 1:90-90:1, can be used for preventing diseases of cereals, fruit trees, and vegetables, possesses excellent synergistic interaction effect, is capable of avoiding and delaying generation of drug resistance of bacteria, and reducing application cost, and is rapid in bactericidal speed, and long in effect lasting period; the prevention effect is better than that of single component. The bactericidal composition can be used for preventing and treating fungus on crops, and especially can be used for preventing and treating fungous diseases such as phytophthora capsici, potato late blight, rice sheath blight disease, cotton damping off, tomato downy mildew, apple rot disease, and cucumber anthracnose, and the effect is better than that of single component.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with syringstrobin and tetramycin as main active ingredients and its application. Background technique [0002] Syringstrobin, commonly known as Coumoxystrobin, is a methoxyacrylate fungicide. It is a protective fungicide and also has a certain therapeutic effect. It has the characteristics of broad spectrum, low toxicity, high efficiency and safety, and has the functions of immunity, prevention, treatment, production and income increase. It has special effects on apple tree rot disease, and is the most authoritative agent for preventing and treating rot disease in the country. It has a wide bactericidal spectrum and is effective against downy mildew, late blight, scab, anthracnose, and leaf mold of melons, vegetables, and fruit trees; at the same time, it is effective against ringworm, anthracnose, cotton wilt, rice blast, and sheath ...
