Abstract

The invention discloses an ethirimol-contained bactericide combination, which comprises A) a first active ingredient ethirimol and B) a second active ingredient quinoxyfen or brasilense cyclamine. The weight ratio of the first active ingredient and the second active ingredient is 1:100-100:1. The ingredient compounding is scientific and reasonable, the prevention and control effects can be obviously improved, the sterilization range can be enlarged, the occurrence of fastness can be stayed, and the safety to the crop is high. The ethirimol-contained bactericide combination has excellent prevention and control effects on various powdery mildew and rust disease.

Description

technical field [0001] The invention relates to a bactericidal composition containing pyrimol and having a synergistic effect on plant diseases such as powdery mildew and rust. Background technique [0002] Powdery mildew is a disease with a wide range of hosts and very serious damage. It often occurs on crops with high economic value such as strawberries, grapes, snow peas, mangoes, melons, and flowers. Triazole agents such as triadimefon, myclobutanil, tebuconazole, and flusilazole can be used to control powdery mildew. Due to long-term single use, the resistance of pathogenic bacteria has increased significantly, and the increase in the concentration and frequency of use will easily lead to drug accidents. [0003] Pyrimidine is a pyrimidine fungicide with high activity against crop powdery mildew. Its mechanism of action is completely different from that of sulfur, kresoxim-methyl (methoxyacrylate fungicide) and triazole fungicides. For bacteria that have developed res...
