Problems solved by technology

Therefore, better prevention and control can only be achieved by increasing the use of fungicides, which will inevitably result in more chemical residues in plants and soil, which will not only endanger food safety, but also cause serious environmental pollution

specific Embodiment approach 1

[0016] Specific implementation mode 1: In this embodiment, the plant-derived fungicides for flat storage are mainly made of the following raw materials in parts by weight: 2.0 to 3.0 parts of flat storage, 0.5 to 1.2 parts of Scutellaria baicalensis, 2.0 to 3.0 parts of black nightshade, and gentian 0.8 to 1.0 parts and 1.0 to 2.0 parts of Atractylodes.

specific Embodiment approach 2

[0017] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the plant-derived fungicides of scutellaria are mainly made of the following raw materials in parts by weight: 2.0 to 2.5 parts of scutellaria, 0.8 to 1.1 parts of Scutellaria baicalensis, 0.8 to 1.1 parts of Scutellaria baicalensis, 2.1 to 2.4 parts of sunflower, 0.8 to 1.0 parts of gentian and 1.2 to 1.5 parts of herb.

specific Embodiment approach 3

[0018] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the plant-derived fungicides of flat storage are mainly made of the following raw materials in parts by weight: 2.4 parts of flat storage, 1.0 parts of Scutellaria baicalensis, 2.3 parts of black nightshade, 1.0 parts of gentian and 1.5 parts of herb.

Abstract

The invention relates to a polygonum aviculare botanical bactericide and a preparation method thereof, belonging to the technical field of pesticides. The invention aims at disclosing a compound botanical bactericide formula and a preparation method thereof. The polygonum aviculare botanical bactericide is mainly prepared from polygonum aviculare, radix scutellariae, black nightshade herb, radix gentianae, rhizoma atractylodis and the like. The preparation method comprises the steps of 1, drying and crushing the raw materials, then sieving and mixing the raw materials; 2, performing ultrasonic treatment on the mixture after being subjected to cold soak in ethanol, filtering to obtain a filtered liquid, evaporating and condensing until the filtered liquid becomes paste. The polygonum aviculare botanical bactericide has a relatively good bacteriostasis function on multiple pathogenic fungal plant pathogens such as rhizoctonia solani, pythium blight pathogen, fusarium graminearum, alternaria solani and carbon-color helminthosporium carposaprum, has the effects obviously better than the chemical disinfectant thiram. The raw materials adopted in the invention are purely natural plants, so that the preparation cost is low, and small-size industrial production can be carried out; furthermore, as the plants are Chinese herbal medicines, the polygonum aviculare botanical bactericide can be degraded rapidly after the use, is safe for people and live stock, good in environmental compatibility and free from secondary pollution to the environment, and meets the current concept of green food and environment sustainable development strategy.

Description

technical field [0001] The invention belongs to the technical field of pesticides; specifically, it belongs to the field of botanical fungicides; in particular, it relates to flat storage botanical fungicides and a preparation method thereof. Background technique [0002] Since the first application of copper sulfate in 1761 to treat seeds to control wheat smut, chemical pesticides have played an important role in the control of plant diseases. For example, carbendazim, thiram and chlorothalonil have been used as the main chemical fungicides to prevent and control some fungal diseases on vegetables, fruit trees and other crops. Continuous use for many years has caused the mutation and resistance of pathogenic bacteria to increase. Therefore, better prevention and control can only be achieved by increasing the use of fungicides, which will inevitably cause more chemical residues in plants and soil, which will not only endanger food safety, but also cause serious environmental...
