Abstract

The invention discloses a bactericide for treating rice bacterial blight. The bactericide is prepared from the following raw materials in parts by weight: 2-3 parts of trifloxystrobin, 20-30 parts of a traditional Chinese medicine extract, 0.5-1 part of methyl salicylate, 0.5-0.7 part of diethyl aminoethyl hexanoate, 1-3 parts of a penetrant, 10-15 parts of a dispersing agent, 8-10 parts of an assistant and 100-200 parts of water, wherein the traditional Chinese medicine extract is prepared from the raw materials, including chenopodium serotinum, galangal, ephedra, acorus tatarinowii, garlic oil and clove oil. Through combined action of the bactericide from two aspects of rice resistance strengthening and external sterilization, so that the bactericide has a good treatment effect on the rice bacterial blight, and the bactericide resistance is not generated.

Description

Technical field [0001] The present invention relates to the technical field of fungicides, and in particular to a fungicide for treating rice bacterial blight. Background technique [0002] Rice bacterial blight is a bacterial disease of rice leaves. The pathogenic bacterium is Xanthomonas oryzae pathogenic species of rice in the kingdom of Prokaryotes. The pathogen invades the rice body through wounds or water holes in the roots, stems, and leaves, and multiplies in the vascular bundles to cause harm. The seedling and tillering stages are most vulnerable. Seedling leaves often show leaf blight symptoms. [0003] Acute wilting symptoms often appear on infected varieties. The lesions are blue-gray and water-soaked, and the diseased leaves quickly curl and wither. Brown dead spots appear on resistant varieties. The optimum temperature for the growth of the pathogen is 26-30°C, and it overwinters on diseased remains. Rice seeds can also carry the bacteria and are spread by ...
