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

Embodiment 2

[0014] Example 2: Bacteriostatic test effect of bactericidal herbicide form

[0015] Field efficacy test of the bactericidal herbicidal pesticide prepared in Example 1 of the present invention for controlling rice sheath blight:

[0016] Each experiment has 3 treatments, 4 repetitions, and each plot area is 10m2. The experimental design is carried out according to a completely random design, among which A: clear water blank control; B: compound carbendazim 800-fold dilution positive control; C: this The 300-fold dilution of the botanical pesticide is invented. The drug was administered 4 times with an interval of 7d.

Abstract

The invention relates to an oil suspension pesticide composition for preventing and treating rice sheath blight disease, which is prepared from the following raw materials in parts by weight: 5-10 parts of matrine, 2-30 parts of validamycin, 10-24 parts of trisiloxane polyethenoxy ether, 20-30 parts of pepper, 20-30 parts of gingko seed coat, 20-30 parts of fructus cnidii and the like. The seed dressing provided by the invention can be used for soil treatment after planting before seedling, and has the characteristic of farmland weed eradication and broad-spectrum sterilization. Compared with the prior art, the formulation provided by the invention has the characteristics of favorable weed eradication effect, high safety for environment and the like, and the weed can not easily generate drug resistance, thereby having wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of pollution-free pesticides, and relates to a biological pesticide fungicide, in particular to a biological pesticide composition for preventing and treating rice sheath blight and a preparation method thereof. Background technique [0002] Plants will encounter various diseases and insect pests in the process of growth in nature, especially fungal diseases. There are many types and serious diseases. For example, golden disease, red gold disease, black gold disease, etc. are common in many crops and are difficult to control. Diseases have brought huge losses to agricultural production, mainly in the tender seedlings, buds, shoots and other parts of crops. In severe cases, the leaves wither, curl, turn brown and die. At present, a large number of chemical methods are used for prevention and control. The domestic drugs used to control powdery mildew mainly include methyl group. However, the singleness of medi...
