The invention relates to a composition for killing harmful fungus, such as sigatoka disease and the like. The composition is characterized in that the composition contains two types of active components: epoxiconazole (chemical name: (2RS,3RS)-1-(3-(2-chlorphenyl)-2, 3-epoxy-2(4-fluorophenyl)propyl)-1-H-1, 2, 4-triazole) and carbendazim (chemical name: benzimidazole-2-benzimidazole methyl carbamate), and the weight ratio between the epoxiconazole and the carbendazim is between 1:0.01 to 1:95. The composition overcomes the defects existing in the prior art, has the extremely remarkable synergistic action, can control the sigatoka disease and other harmful fungi by applying smaller dosage and can display extremely strong bacteria resistance and bactericidal activity.
Description
technical field [0001] The invention relates to a fungicide composition with synergistic effect, which can effectively prevent and control harmful fungi such as banana leaf spot bacteria, has protective and therapeutic effects on crops, and exhibits extremely 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 aging of plants, affects fruit filling, and can reduce yield by 30% to 50%. 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 current...
