Abstract

The invention discloses a bactericide for controlling rice sheath blight disease. The bactericide is prepared from raw materials in parts by weight as follows: 5-8 parts of picoxystrobin, 25-35 parts of traditional Chinese medicine extract, 0.8-1.2 parts of methyl jasmonate and 0.4-0.8 parts of brassinosteroid, 2-4 parts of a penetrant, 16-18 parts of a dispersant, 8-10 parts of glycerin and 100-200 parts of water, wherein the traditional Chinese medicine extract comprises raw materials as follows: radix phytolaccae, herba asari, fructus viticis, semen ginkgo, fructus forsythia oil, cortex cinnamomi oil and rhizoma zingiberis oil. The bactericide does not produce drug tolerance and has good effect on controlling bacterial blight of rice.

Description

technical field [0001] The invention relates to the technical field of fungicides, in particular to a fungicide for treating rice blight. Background technique [0002] Rice sheath blight, also known as moire, is commonly known as flower foot stalk, rotten foot blast, eyebrow spot. It is caused by infection by Rhizoctonia solani, and it mostly occurs under high temperature and high humidity conditions. Sheath blight is one of the major diseases in rice production, which is a serious hazard in southern rice areas. The disease prevents the rice from heading, or there are more grains in the heading, and the grain weight decreases. [0003] The pathogen mainly survives the winter in the soil with sclerotia, and can also survive the winter with mycelium on diseased residues or on other hosts such as field weeds. During spring irrigation in the following spring, the sclerotium floats on the water surface and mixes with other debris. After transplanting, the sclerotia adheres to ...
