Bacillus cereus water agent for the well

Abstract

The invention relates to a jinggangmycin / bacillus cereus aqueous solution for preventing and curing the fungous diseases such as sheath and culm blight of rice, green smut, wheat sharp eyespot, and so on. The composite aqueous solution is obtained by the jinggangmycin, the bacillus cereus and the accessory ingredient filler. A milliliter of the composite aqueous solution contains the jinggangmycin A3.0*10<4>Mug-12.0*10<4>Mug and the bacillus cereus 0.6-1.6 billion living spores. A dispersing agent MF and a detergent LS are adopted in the accessory ingredient filler. Since the jinggangmycin / bacillus cereus aqueous solution is the composition of the biological resistance type yield increasing bacteria and the biological antibiotic, the solution has double effects of antibiotic and antivirus, improves the effect of preventing disease, and increases the output. Compared with the prior art, on one hand, the jinggangmycin A constituent content is added to give full play to the prevention and cure effect of the jinggangmycin against the fungous diseases, on the other hand, the usage amount of the bacillus cereus is reduced to lower the product cost and widen the popularization and application prospect.

Description

technical field [0001] The invention relates to a biological agent for preventing and treating fungal diseases such as rice sheath blight, rice smut and wheat sheath blight, and in particular to a compound water agent of Jinggangmycin and Bacillus cereus. Background technique [0002] The traditional pesticide used to control rice sheath blight is Jinggangmycin, which has been used alone for more than 30 years. The sheath blight bacteria have developed resistance to it, and the control effect has declined. How to improve the control effect of Jinggangmycin on rice sheath blight and how to develop and research new preparations to improve the original control effect of Jinggangmycin have become the key points for those skilled in the art. [0003] The Chinese invention patent with the notification number CN1116800C and the announcement date of August 6, 2003 discloses a synergistic Jinggangmycin water preparation composition, which contains 1.0×10 Jinggangmycin in each millili...

Problems solved by technology

[0005] But, as mentioned above, because the sheath blight pathogen strengthens the resistance to Jinggangmycin, the above-mentioned disclosed invention technical scheme still fails to most effectively improve the disease resistance of biological antibiotics---Jinggangmycin, which is harmful to rice. Although the prevention and treatment of sheath blight has been effectively improved, it has not been fully brought into play; simultaneously because the market price of biological disease-resistant synergistic bacteria—Bacillus cereus is relatively expensive, the above-mentioned disclosed technical scheme of the invention is due to The amount of Bacillus cereus used is relatively high, the production cost is high, and it is difficult to popularize and apply
