Abstract

The invention relates to a method for preventing rice blast at the rice seedling stage, which uses pesticide granules containing allyl thiazole and iprodione for prevention and treatment, and the weight ratio of allyl thiazole and iprodione is: 5-8: 2-3, preferably, the weight ratio of allylbenzothiazole and iprodione is 8:2. The application rate is 0.1 kg / m 2 . The invention is suitable for preventing and treating rice blast in the dry seedling raising period, and the formula has obvious synergistic effects, good systemic absorption, can effectively control diseases, and has the effect of saving time, labor and effort.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a method for preventing rice blast at the rice seedling stage. Background technique [0002] Allyl benzothiazole, common name in English: probenazole, is an immune-inducing fungicide developed by Japan Meiji Seika Pharmaceutical Co., Ltd. It achieves the disease prevention effect by stimulating the immune (resistance) response of the plant itself to the disease. It is absorbed through the roots of plants, and penetrates and transmits to all parts of plants relatively quickly. Allylbenthiazole treatment of rice can promote root absorption and protect crops from infection by blast fungus and bacterial blight. [0003] Iprodione, the common name in English: iprodione, is a broad-spectrum contact-type protective fungicide, which has a certain therapeutic effect and can also be absorbed through the root to play a systemic role. It is suitable for the control of leaf spot, gray mo...
