Compound bactericide

Abstract

The invention discloses a compound bactericide. The bactericide comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is fluindapyr, the active ingredient B is one or two selected from N-(2-(2-chloro-4-trifluoromethylphenoxyl)phenyl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-amide and N-(2-(2,4-dichlorophenoxyl)phenyl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-3-amide, and the weight ratio of the active ingredient A to the active ingredient B is 1:50 to 50:1. The compound bactericide provided by the invention can be prepared into conventional preparations such as a suspension agent, an aqueous emulsion, a suspoemulsion, a microcapsule suspension agent, a suspension seed coating agent, wettable powder, a water-dispersible granule, a granule and a dispersible oil suspension agent. The compound bactericide provided by the invention has a higher control effect on a plurality of diseases of a plurality of crops, an obvious bactericidal effect, a wide bactericidal spectrum, and an obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a compound fungicide containing fluindazole. Background technique [0002] Fluindazole chemical name: 3-difluoromethyl-N-(7-fluoro-2,3-dihydro-1,1,3-trimethyl-1H-inden-4-yl)-1- Methyl-1H-pyrazole-4-carboxamide belongs to broad-spectrum SDHI fungicides. The bactericidal spectrum covers all the bactericidal spectrums of Thiofuramide and Lunason. In addition to the special effect against Rhizoctonia solani, it is effective against anthrax, rust, Early blight, powdery mildew, leaf mold, rice smut are all very effective. Especially in terms of powdery mildew, it is more active than Lunasen and Lufei. The structural formula is as follows: [0003] [0004] Fluphenamide is a pyrazole amide compound developed by Central China Normal University. It has a good control effect on rice and wheat sheath blight, and also has a certain control effect on cucumber, tomato and other crops an...

Problems solved by technology

[0008] Due to the current non-standard use of pesticides, the resistance of diseases to pesticides is getting stronger and stronger, resulting in higher and higher use of pesticides, causing environmental pollution

Through our experimental research, it has been shown that the compounding of fluindaclostrobin with flufenoxamide and chlorophenylene ether amide has obvious synergistic effect within a certain range, which can well overcome the shortcomings of existing products and improve efficacy, reduce usage, and there are no relevant reports at home and abroad
