Abstract

The invention relates to a special bactericidal composition for apple glomerella leaf spot and application thereof. The bactericidal composition takes ziram and pyraclostrobin as main active components, wherein the weight ratio of ziram to pyraclostrobin is (1-6) to (1-6). According to the special bactericidal composition, different types of bactericides, protective bactericides and systemic bactericides, particularly ziram and pyraclostrobin, are compounded according to a certain ratio and are prepared into a certain preparation; the prevention and treatment effect on the glomerella leaf spot can be remarkably improved and the special bactericidal composition especially has the optimal prevention and treatment effect on the apple glomerella leaf spot (GLS) and has an obvious synergistic effect; and the special bactericidal composition is safe to crop and has a wide application prospect in a production process.

Description

technical field [0001] The invention relates to a special bactericidal composition for apple anthracnose leaf blight and application thereof, belonging to the technical field of pesticides. Background technique [0002] Pyraclostrobin, also known as pyraclostrobin, English common name: Pyraclostrobin, chemical name: N-[2-[[1-(4-chlorophenyl)pyrazol-3-yl]oxymethyl]benzene Base]-Methyl N-methoxycarbamate. Pyraclostrobin belongs to the methoxyacrylate fungicides, which mainly acts on the cytochrome bel complex in the mitochondrial respiratory chain of fungi, preventing electron transfer and thus inhibiting fungal growth. Pyraclostrobin can prevent and control all types of fungal pathogens, and has a wide bactericidal spectrum. It is mainly used to control grape powdery mildew and downy mildew; wheat powdery mildew and rust; barley leaf rust; banana black leaf streak disease; tomato early and late disease and other diseases. Pyraclostrobin is effective against various disease...
