Environmentally-friendly fungicide specially used for rice breeding

Abstract

The invention discloses an environmentally-friendly fungicide specially used for rice breeding. The environmentally-friendly fungicide is characterized by being prepared from the following raw materials in parts by weight: 3-16 parts of modified triadimefon, 4-13 parts of chitosan quaternary ammonium salt, 2-5 parts of brassinolide, 1-4 parts of cinnamamide, 2-10 parts of plant polysaccharides, 0.1-1.3 parts of benzyl chloride, 0.3-2 parts of diethylene triamine, 0.1-0.9 part of polylysine, 1-3 parts of lavender essential oil, 2-5 parts of sanguinarine, 1-3 parts of chelerythrine, 1-4 parts ofan ethanol extract from herba sophorae alopecuroidis, 0.3-2 parts of an ethanol extract from cynanchum komarovii, 10-15 parts of a dispersing agent, 3-10 parts of a wetting agent, 0.1-0.5 part of rooting power, 50-100 parts of filler and 5-13 parts of a disintegrating agent. The environmentally-friendly fungicide, provided by the invention, specially used for rice breeding is good in fungicidal property and environmentally-friendly, does not cause drug resistance, and can increase the yield of breeding.

Description

technical field [0001] The invention relates to the technical field of rice breeding, in particular to a special environment-friendly fungicide for rice breeding. Background technique [0002] Rice is one of the most important food crops in my country and occupies an important position in the national economy. Its sown area, total output and per unit yield all rank first in food crops, which shows the importance of rice. However, in the process of rice planting, diseases such as bakanae disease and blight often appear, thereby reducing the yield of rice planting and reducing the quality of rice. The use of fungicides is an important means to prevent and control rice diseases. However, most of the existing fungicides for rice are pure chemical agents, which are expensive, easy to cause drug resistance in rice, and the effect is not very good. Increased pollution to the environment. Contents of the invention [0003] Based on the technical problems in the background techno...
