Green pesticide used for preventing and controlling rice sheath blight disease and preparation method thereof

Abstract

The invention discloses green pesticide used for preventing and controlling rice sheath blight disease. The green pesticide used for preventing and controlling the rice sheath blight disease is prepared from the following Chinese herbal medicines with sterilization, deinsectization and detoxification functions: buddleja myriantha, alchornea davidii, macleaya cordata, actinodaphne cupularis gamble, swamp mahogany leaf, bark of Chinese catalpa, myrcia tree, lysimachia foenum-graecum hance and desert asparagus. The green pesticide used for preventing and controlling the rice sheath blight disease has good control efficiency on the rice sheath blight disease, a field contrast test shows that the control efficiency is 80.1% and is obviously better than 60.9% of a contrast group, a yield increasing effect is obvious, and the green pesticide used for preventing and controlling the rice sheath blight disease has the advantages of environmental friendliness, safety, ecology and simple compatibility of medicines.

AI Technical Summary

Benefits of technology

This patented technology described in this patent allows us to extract useful components (such as flavonoids) found naturally occurring throughout China's indigenous plantations that can be used to treat diseases such as rice borer or insect damage caused by these plants. These extra compounds help improve crop health without causing harmful side effects like weed killers or chemical agents. They were obtained through traditional methods involving burning roots with harsh acidic solutions at different temperatures.

Problems solved by technology

This patented technical problem addressed by this patents relates to controlling or reducing plant bacterial wilt caused by certain types of soilborne fungi called Rhizoctonia solani (RSC). Current methods involve applying chemicals that can harm humans' bodies but they cannot be applied indiscriminately without affecting beneficial plants like crop roots. Therefore there needs an improved method of protecting crops while minimizing environmental impact during their growth period.
