Composition for preventing harmful eumycetes such as sigatoka

Abstract

The invention relates to a composition for preventing and curing harmful eumycete such as sigatoka, and the like, which contains two active ingredients of tebuconazole (chemical name: (RS)-1-rubigan-4,4-dimethyl-3-(1H-1,2,4-triazole-1-ylmethyl)-3-alcohol) and epoxiconazole (chemical name: (2RS, 3RS)-1-[3-(2-chlorphenyl)-2,3-epoxy-2-(4-fluorophenyl) propyl]-1H-1,2,4-triazole), wherein the weight ratio of the tebuconazole and the epoxiconazole is 1:0.1-1:10. The composition overcomes the defect of the prior art, shows remarkable synergized action, and treats harmful eumycetes such as sigatoka, and the like by lower dose, thereby representing strong antibiosis and bactericidal activity.

Description

technical field [0001] The invention relates to a fungicide composition with synergistic effect. The fungicide composition can effectively prevent and treat harmful fungi such as banana leaf spot bacteria, has protective and therapeutic effects on crops, and exhibits strong antibacterial and bactericidal activities. The invention belongs to the field of agricultural plant protection. The fungicide composition is different from other existing fungicides. Background technique [0002] Banana leaf spot is one of the most important diseases of bananas. Leaf spot disease mainly damages banana leaves, causes banana leaves to dry up, significantly reduces the photosynthetic area of ​​leaves, causes premature plant aging, affects fruit filling, and reduces banana yield. In addition, the quality of the fruit of the diseased plant is not good, it is not resistant to storage, and it is easy to rot. For such diseases, the use of chemical agents to prevent and control is currently the...
