Abstract
The invention provides a bismerthiazol fungicide-containing composition and application thereof. Effective components in the composition comprise the following components in parts by weight: 1 to 50 parts of metconazole and 1 to 50 parts of a fungicide kresoxim-methyl. Compared with a single dosage, the composition provided by the invention has an obvious synergistic effect of preventing and treating powdery mildew and can obviously enhance the prevention and treatment effect, replace a highly toxic fungicide used in the department, reduce the fungicide use amount, lower the environmental pollution, reduce the amount of residual fungicides in agricultural products and delay the onset time of the fungicide resistance of the powdery mildew to the fungicide; compared with a single agent, thecomposition can reduce the cost.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a fungicide composition containing metconazole and kresoxim-methyl and its application. Background technique [0002] Powdery mildew can occur from seedling to heading. It mainly harms wheat leaves, but also stems and ears. Small yellow dots start to appear on the leaves, and then expand and develop into round or oval lesions with a white powdery mold layer on the surface. Generally, the lower leaves are more than the upper leaves, and the back of the leaves is more than the front. The mildew spots disperse individually in the early stage, and then combine to form a large mildew spot, which can even cover the whole leaf, seriously affecting photosynthesis, disturbing normal metabolism, causing premature aging, and loss of yield. [0003] Control object metconazole, the chemical name of metconazole is: 5-(4-chlorophenyl)-2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl base) cyc...
