Abstract

The invention discloses a seed coating agent for preventing and treating rice bakanae disease. The seed coating agent is prepared from fludioxonil, tebuconazole, filler, a suspending aid, warning coloration, an anti-freezing agent, a preservative, a film-forming agent, a dispersing agent and water. The seed treatment agent is prepared by mixing a broad-spectrum contact bactericide and a triazole bactericide, and the product inhibits the growth of fungal mycelia through the comprehensive effects of inhibiting transfer related to glucose phosphorylation, inhibiting biosynthesis of ergosterol of fungi and the like, and finally causes pathogen death. The product has multiple prevention effects of protection, contact killing, treatment, eradication, internal absorption and the like. The product disclosed by the invention has a relatively good prevention and treatment effect on the rice bakanae disease.

Description

technical field [0001] The invention relates to the technical field of seed coating agents, in particular to a seed coating agent for preventing and treating rice bakanae disease and a preparation method thereof. Background technique [0002] Rice bakanae disease, also known as excessive growth disease, occurs in every rice area in China. Diseased grains often do not germinate or cannot be unearthed after sowing. The diseased seedlings are thinner and taller than the healthy seedlings at the seedling stage, the leaf sheaths are slender, the leaf color is light yellow, the root system is underdeveloped, and some diseased seedlings die before transplanting. There are light red or white mold powder on the dead seedlings, which are conidia of pathogenic bacteria. When the humidity is high, the surface of the dead diseased plants is covered with light brown or white powdery mildew, and black dots are formed in the later stage, which are the fungus capsules. Those with mild dis...
