Abstract

The present invention relates to a bactericidal composition comprising an active ingredient, the active ingredient comprises a first active component and a second active component, the first active component is oxathiapiprolin, and the second active component comprises at least one of fluopyram, imazalil and boscalid. The active components in the bactericidal composition can be well synergistically enhanced, and the bactericidal composition has prevention, treatment and spore production inhibition effects on various crop diseases, has excellent bactericidal activity, and has strong inhibitoryeffects on pathogenic bacteria in various developmental stages. The bactericidal composition can be transported for a long distance in host plants, can also effectively control diseases under extremely harsh conditions, and has a very good control effect on various diseases that occur simultaneously in various crops.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular to a fungicidal composition and its application. Background technique

[0002] In agricultural production practice, there are often problems of mixed occurrence of different types of diseases, which are diseases that often exist at the same time or successively, such as gray mold, late blight, downy mildew, anthracnose, powdery mildew, white rot, etc. Grapes, tomatoes, cucumbers, apples, strawberries, peanuts, potatoes and other crops.

[0003] For the above common diseases, different pesticides are often used for prevention and control. For example, pyrimethanil or iprodione is generally used for control of gray mold; late blight is generally controlled by mancozeb or mancozeb; Metalaxyl or chlorothalonil is used for control; anthracnose is generally controlled by tebuconazole or prochloraz; powdery mildew is generally controlled by pyrimethoxazole or propiconazole; white rot i...
