Abstract

The invention discloses a bactericidal composition of azoxystrobin and mancozeb. The bactericidal composition contains azoxystrobin, mancozeb and other auxiliary agents, wherein the weight ratio of azoxystrobin to mancozeb is (1-10): (60-1). The bactericidal composition of azoxystrobin and mancozeb can be applied to prevention and control of potato late blight. The composition is wide in application range, low in cost and good in effect. The indoor test proves that the composition has obvious synergized action.

Description

technical field [0001] The invention belongs to the field of pesticide compounding, and relates to a bactericidal composition and its application, in particular to a bactericidal composition with azoxystrobin and mancozeb as main active ingredients and its application. Background technique [0002] In recent years, due to single and unscientific use of drugs, many diseases have become resistant to the currently used pesticides, such as late blight, powdery mildew, gray mold, anthracnose, etc., which has become a major problem in chemical control. At the same time, frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, low toxicity and environmental protection. [0003] Azoxystrobin (Azoxystrobin) is a brand-new methoxyacrylate fungicide with triple effects of protection, treatment and eradication. It destroys the energy synthesis...
