Problems solved by technology

Especially in recent years, there is generally insufficient amount of medicinal liquid used by farmers, and rice sheath blight occurs mainly in the middle and lower parts of rice. Due to insufficient medicinal liquid, it is difficult for live bacteria to reach the diseased part. This is the effect of biological pesticides on rice grains. Blight control efficiency is slightly lower than one of the main factors of chemical pesticides
At present, there are also some plant pesticides extracted from Sophora flavescens, but the formula is unreasonable, the effect is not ideal, and it is not suitable for industrial production. The market is in urgent need of a plant that is conducive to environmental protection, can effectively sterilize and weed, and can be suitable for large-scale production. pesticide

Abstract

The invention relates to a suspoemulsion pesticide composition for controlling Rhizoctonia solani, which is prepared from the following raw materials in parts by weights: 5-10 parts of sophocarpidine, 2-30 parts of validamycin, 10-24 parts of trisiloxane polyoxyethylene ether, 20-30 parts of pepper, 20-30 parts of gingko seed coats and 20-30 parts of fructus cnidii. The suspoemulsion pesticide composition can be used for soil treatment after sowing and before emerging of seedling, and has the characteristic of killing farmland weed and a broad-spectrum sterilization characteristic. Compared with the prior art, the suspoemulsion pesticide composition has the characteristics of good weed removing effect and the safety to the environment, and weeds hardly generating resistance to the suspoemulsion pesticide composition can not be generated easily, so that the suspoemulsion pesticide composition has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of pollution-free pesticides, and relates to a biopesticide bactericide, in particular to a biopesticide composition for preventing and treating rice sheath blight and a preparation method thereof. Background technique [0002] Plants will encounter various diseases and insect pests during their growth in nature, especially fungal diseases. There are many types and serious diseases. For example, gold disease, red gold disease, and black gold disease are common and difficult to control on many crops. Diseases have brought huge losses to agricultural production, and mainly occur in the tender seedlings, buds, shoots and other parts of crops. When severe, the leaves withered, curled, turned brown, and died. At present, a large number of chemical means are used for prevention and control. The main agents used for the prevention and treatment of powdery mildew in China are methyl. Harmful, and there are residues...
