Problems solved by technology

[0002] Due to the long-term use of chemical fertilizers, chemical pesticides, and high-intensity multiple cropping and continuous cropping farming methods, there have been problems such as increased resistance to diseases and insect pests, reduced soil sustainable production capacity and fertilizer use efficiency, and damage to the quality of cultivated land. Insufficient organic matter, soil compaction, decline in fertility, frequent occurrence of soil-borne diseases and continuous cropping obstacles, and increasingly serious problems in the quality and safety of agricultural products have restricted the development of my country's agriculture.

Abstract

The invention provides clonostachys rosea-bacillus subtilis composite wettable powder containing clonostachys rosea fungus conidial powder for preventing and treating gray mold, sheath blight, root rot, fungal leaf spot and sclerotinia rot and bacillus subtilis bacterial spore powder for preventing and treating bacterial wilt, soft rot diseases, canker, bacterial spot diseases and bacterial angular leaf spot diseases. The wettable powder comprises, by weight, 50-100 parts of clonostachys rosea fungus conidial powder, 50-100 parts of bacillus subtilis bacterial spore powder, 800-850 parts of diatomite, 10-20 parts of sodium dodecyl benzene sulfonate, 10-50 parts of sodium lignosulfonate, 10-50 parts of carboxymethylcellulose sodium and 5-10 parts of ascorbic acid. The wettable powder composite microbes do not produce antagonistic action, have a wide sterilization spectrum, are safe for crops, users and an environment, improve crop quality and improve a yield and performance stability.
