Abstract
The invention discloses a sterilizing combination containing metrafenone and triazole fungicide. The first active ingredient of the sterilizing combination is metrafenone, and the second active ingredient is selected from triazole fungicide, such as epoxiconazole, tetraconazole, metconazole and ipconazole, and the weight ratio of the first active ingredient to the second active ingredient is 1:20 to 20:1. The combination can be prepared into agriculturally allowable water dispersible granules, wettable powder, suspending agent, missible oil or microemulsion formulations. The sterilizing combination has the advantages that components are reasonable, the sterilizing effect is good, the pesticide application cost is low, the activity and the sterilizing effect of the combination are not the simple superposition of the activity of all the components, and compared with the existing single formulation, the combination not only has obvious sterilizing effect, but also has obvious potentiation, is pollution-free to the environment, has high safety, meets the safety requirement of pesticide formulation, and has obvious prevention effect on powdery mildew of crops.
Description
technical field [0001] The invention relates to a bactericidal composition containing metrafenone and a triazole bactericide, belonging to the technical field of compound pesticides. Background technique [0002] Metrafenone, English common name: Metrafenone, chemical name: (3-bromo-6-methoxy-2-methylphenyl)-(2,3,4-trimethoxy-6-methylphenyl) Ketone is an agricultural fungicide developed by BASF. It can protect, treat and inhibit spore production for various types of crop powdery mildew. [0003] Epoxiconazole, other names: Oubo, English common name: epoxiconazole, chemical name: (2RS, 3SR)-3-(2-chlorophenyl)-2-(4-fluorophenyl)-2-[(1H1 , 2,4-triazol-1-yl)methyl]oxirane. Epoxazole is a systemic triazole fungicide, its active ingredient inhibits the synthesis of ergosterol of pathogenic bacteria, hinders the formation of bacterial cell walls, and can more effectively inhibit pathogenic fungi. It has a good control effect on leaf spot, powdery mildew, rust on bananas, onions...
