Caprotrahol and Bacillus subtilis compound agricultural chemicals

Abstract

A compound agricultural chemical in the form of wettable powder, solution, microemulsion, suspension, water disperser, particle, emulsified oil, or aquatic emulsion for preventing and eliminating diseases and pests of rice, cotton, vegetables, fruit tree, etc, especially the green smut and sheath and culm blight of rice, is proportionally prepared from Bacillus subtitis, hexaconazole, functional assistant, filler and carrier.

Description

Technical field [0001] The invention relates to a compound pesticide, in particular to a compound pesticide which has certain effects on rice sheath blight and rice false smut. Specifically, it is a compound pesticide of hexaconazole and Bacillus subtilis. Background technique [0002] Rice sheath blight is common in rice-growing countries in Asia, America, and Africa. It is distributed in all rice areas in my country, but it is common in rice areas south of the Yangtze River, and can occur in early, middle, and late rice, causing a significant decrease in seed setting rate and thousand-grain weight, and even plants lodging and dying. Dwarf varieties suffer more. Due to the wide area of ​​occurrence and the high frequency of epidemics, the losses caused by it often exceed that of rice blast, and the yield of severe fields is reduced by about 60%. Rice false smut is also called green powdery mildew. Rice is usually susceptible to the disease at the heading and flowering st...

Problems solved by technology

[0003] For a long time, the control of rice sheath blight has been dominated by the agricultural antibiotic Jinggangmycin, but Jinggangmycin has been widely used since the 1970s, with a long period of time, the dosage of the drug is gradually increasing, and the resistance is enhanced. It has increased several times and the control effect is slow. Once an outbreak occurs, it will be difficult to control in a short period of time. The prevention and treatment of rice false smut mainly relies on organic pesticides, which have large residues and affect people's health.
