[0008] Methoxyacrylate fungicides are a new type of fungicides that have emerged in recent years. They are currently one of the main types of fungicides in the market for the prevention and treatment of fungal diseases. The market share is very large. This type of fungicides has high activity but a single target. This also leads to the rapid occurrence of bacterial resistance. For example, some of these agents are not as good as before in the prevention and treatment of powdery mildew. Even if the dosage is increased, they cannot achieve the desired effect. Matching research is imminent

The invention discloses a composite synergistic bactericidal composition containing isopyrazam and azoxystrobin and application thereof. The bactericidal composition takes isopyrazam and azoxystrobin as main effective components, wherein the isopyrazam and azoxystrobin are in a weight ratio of 1-60:1-70. The bactericidal composition can be used for preventing and treating diseases of cereal crops, vegetables and fruit trees, has a high synergistic effect, prevents and delays the drug resistance of bacteria, has a fast bactericidal speed, longer duration and reduced application cost, and the prevention and treatment effects are significantly better than those of a single agent. The composite synergistic bactericidal composition containing isopyrazam and azoxystrobin provided by the invention can be used for preventing and treating fungal diseases in crops, especially can be used for preventing and treating rust disease, powdery mildew, leaf spot disease, net blotch, glume blight, scab, rice blast and other fungal diseases, and has better effects than single agent.
Description
Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a compound synergistic bactericidal composition with pyraclostrobin and azoxystrobin as main active ingredients and its application. Background technique [0002] Isopyrazam, chemical name: 3-difluoromethyl-1-methyl-N-[1,2,3,4-tetrahydro-9-(1-methylethyl)-1 ,4-methanonaphthalen-5-yl]-1 H-pyrazole-4-carboxamide, molecular formula C 20 h 23 f 2 N 3 O, Isopyrazam has the following four isomers, the present invention includes any one or a mixture of several, and the chemical structural formulas are as follows: [0003] [0004] Pyrafenapyr was developed by Syngenta. This fungicide has broad-spectrum activity and has excellent control performance on various diseases on various crops. It is resistant to triazoles and methoxyacrylates. It is highly effective against sexual strains of pathogens, especially against Septoria fungi. For example, it is superior to ep...
