Problems solved by technology

[0002] At present, most of the existing insecticides and fungicides are chemical pesticides, which have low efficacy and long residual toxicity period, which seriously affect the crop growth environment and the health of humans and animals.
According to literature reports, the utilization rate of most pesticides is generally 10%, and about 90% of the remainder remains in the environment, which is likely to cause pollution of air, water, soil, agricultural, livestock, fish and fruit products, and thus transfer to humans through food chain enrichment. in vivo, harmful to the human body

Embodiment 1

[0013] Embodiment 1: Preparation of pesticide liquid:

[0014] Prepared by weighing the following raw materials according to percentage by weight: 1% of Panax notoginseng polysaccharide with a content of 80% of the original drug, 4% of surfactant, 3% of synergist, 4% of thickener, and supplemented by wetting agent to 100%.

[0015] Preparation method: Dissolve Panax notoginseng polysaccharide into a 0.1% aqueous solution, centrifuge at 5000 rpm for 12 minutes, remove the precipitate and add water to volume to obtain a 0.1% polysaccharide aqueous solution. Weigh the dispersant, surfactant, synergist, thickener and wetting agent by weight, add it to the reaction kettle, add deionized water, stir evenly at high speed, grind it through a grinder, and then add Panax notoginseng polysaccharide The solution was stirred evenly.

Embodiment 2

[0016] Embodiment 2: Preparation of pesticide water-dispersible granules:

[0017] Prepared by weighing the following raw materials in percentage by weight: the content of the original drug is 85%, the content of the original drug is 15%, the surfactant is 3%, the synergist is 2%, the thickener is 5%, and the wetting agent is supplemented to 100%.

[0018] Preparation method: prepare the Panax notoginseng polysaccharide into a 5% aqueous solution, then add the surfactant, synergist, thickener, and wetting agent into the reaction kettle, add deionized water, stir evenly at high speed, and grind Grinding in a machine, adding water, and granulating in a rotary fluidized bed granulator to prepare a water dispersion.

Embodiment 3

[0019] Embodiment 3 prepares pesticide suspension concentrate:

[0020] According to the percentage by weight, the following raw materials are weighed and prepared: the content of the original drug is 97%, 15% of the original drug of Panax notoginseng polysaccharide, 3% of the surfactant, 5% of the dispersant, and the wetting agent is supplemented to 100%.

[0021] Preparation method: Weigh the surfactant, dispersant, and wetting agent by weight and add them to the reaction kettle, add water, stir evenly at high speed, grind them with a grinder, add panax notoginseng polysaccharide, stir evenly and mix evenly, and prepare a suspension agent.

Abstract

The invention relates to the technical field of pesticide preparation, in particular to a pesticide containing notoginseng polysaccharide. The pesticide comprises a panax notoginseng polysaccharide raw drug containing notoginseng polysaccharide as the main component, a preparation and a pesticide chemically acceptable auxiliary material, wherein the panax notoginseng polysaccharide pesticide raw drug content is 80-99.9 percent, the weight percentage of the raw drug in the panax notoginseng polysaccharide pesticide preparation is 0.1-80 percent, and the rest is auxiliary material. Aiming at thedeficiency of the prior art, the invention provides a pesticide containing notoginseng polysaccharide with reliable performance, which not only has good disease control effect, but also has the advantages of low toxicity, low residue and the like. Compared with chemical pesticides, the invention has the advantages of high safety, small influence on ecological environment and good disease controleffect.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a pesticide containing notoginseng polysaccharide. Background technique [0002] At present, most of the existing insecticides and fungicides are chemical pesticides, which have low efficacy and long residual toxicity period, seriously affecting the crop growth environment and the health of humans and animals. According to literature reports, the utilization rate of most pesticides is generally 10%, and about 90% of the remainder remains in the environment, which is likely to cause pollution of air, water, soil, agricultural, livestock, fish and fruit products, and thus transfer to humans through food chain enrichment. In vivo, harmful to the human body. [0003] With people's higher and higher requirements for environmental protection, botanical pesticides will undoubtedly be one of the main development directions of pesticides in the future. Botanical pesticides...
