Abstract

The present invention relates to the field of fungicides, more specifically, the present invention relates to a plant fungicide composition, a fungicide and applications thereof, the plant fungicide composition comprising 4-chloro-2-(1,1-dimethylethyl )-5-[[[4-(1,1-dimethylethyl)phenyl]methyl]thio]-3(2H)-pyridazinone and pyrithrimol sulfonate. The plant fungicidal composition provided by the invention can effectively control downy mildew, late blight, blight, damping-off, powdery mildew, rust, anthracnose, root rot, black shank on vegetables, fruits and field crops, especially It has an extremely significant control effect on powdery mildew, greatly reduces the dosage of pesticides in the field, reduces pesticide residues and environmental pollution, and reduces production and use costs; at the same time, the fungicide provided by the invention is a nanopesticide with uniform texture and can be used in high and low temperature conditions. Good stability, suitable for a variety of fungicide dosage forms, suitable for flying control, spraying, dusting or fumigation.

Description

technical field [0001] The invention relates to the field of fungicides, more specifically, the invention relates to a plant fungicide composition, a fungicide and applications thereof. 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 cucumber powdery mildew, wheat powdery mildew, banana leaf spot, etc., which has become a major problem in chemical control. At the same time, frequent application of pesticides not only increases the burden on farmers but also aggravates environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, low toxicity and environmental protection. [0003] Acrimolsulfonate, common name in English (Bupirimate), chemical name 5-butyl-2-ethylamino-6-methylpyrimidine-4-dimethylaminosulfate, molecular formula: C 13 h 24 N 4 o 3 S. The drug is a pyrimidine systemic fungicide, and ...
