Compound bactericide for preventing and controlling scab of wheat

Abstract

The invention discloses a compound bactericide for preventing and controlling scab of wheat. The compound bactericide is prepared from the following raw materials in parts by weight: 10 to 20 parts of toxin degrading mixture, 5 to 10 parts of high-efficiency antagonistic microbe, 10 to 20 parts of cyanoacrylate, 3 to 6 parts of resistance-enhancing hymexazol, 8 to 16 parts of micro / nanometer air bubble ozone water with concentration of 7.8 to 8.3mg L<-1>, 14 to 20 parts of nanometer water-borne adhesive, and 3 to 5 parts of carbon enzyme. The compound bactericide has the advantages that the compound bactericide is formed by compounding the bactericide, the high-efficiency antagonistic microbe and multiple toxin degrading bacteria, the micro / nanometer air bubble ozone water is used, the generation of scab of wheat is effectively controlled, and the inhibiting and degrading effects on the breeding of fusarium toxin in the later period of wheat filling are realized; compared with the conventional preventing and controlling method, the content of fusarium toxin in the wheat can be reduced by 50% to 70%; by adding the toxin degrading and adsorbing preparation, the injury to crops and animals by toxin can be obviously reduced through the microbe degrading and biological adsorbing.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a compound fungicide for preventing and treating wheat scab. Background technique [0002] Wheat is the most important cereal cultivated crop in the world, and it is also an important food crop in my country. Scab, powdery mildew, sheath blight, rust and leaf blight are important fungal diseases that threaten wheat production, seriously affecting the yield and quality of wheat. In particular, wheat head blight caused by Fusarium can not only cause devastating yield loss, but also produce a large amount of toxins such as deoxynivalenol and zearalenone in the infected grains, seriously affecting Food security threatens human and animal health. Wheat head blight is an ascomycete disease that can cause bud rot, seedling rot, and ear rot / ear blight caused by a variety of Fusarium species, or Fusarium spp. Its pathogens include nearly 20 species of Fusarium graminearum, Fusarium asiatica,...

Problems solved by technology

What is more serious is that the resistance of wheat head blight will lead to a significant increase in the synthesis of DON toxin, which will aggravate the damage of wheat head blight and the risk of food safety

At present, wheat head blight is still mainly controlled by carbendazim single agent or compound agent containing carbendazim. Due to the increase of drug-resistant groups, farmers often double the use of carbendazim to reduce yield loss. The actual dosage used in production is often 2-3 times the recommended dosage of the preparation, and the frequency of application has also increased, further exacerbating the problems of drug resistance, pesticide residues, environmental pollution and food safety
