Problems solved by technology

However, matrine botanical pesticides also have their own disadvantages: first, the complex structure of the compound makes it difficult to synthesize; second, the distribution of raw material plants is regional, and there are many limiting factors in the selection of processing sites; third, the collection of raw materials Seasonal, sources are limited
There is no patent report on the synergistic pesticide composition with matrine and tea saponin as active ingredients

Embodiment 1

[0013] Embodiment 1: preparation of 21% matrine · tea saponin water

[0014] The weight percent (%) of insecticidal active ingredients is: matrine 1.0, tea saponin 20.0;

[0015] The weight percent (%) of each component of the auxiliary agent is: surfactant: sodium dodecylbenzenesulfonate is 5.0, potassium sorbate is 1.0, and the balance is deionized water.

[0016] Dissolve matrine and tea saponin in ethanol, add other ingredients, homogenize and disperse, and obtain the water preparation.

Embodiment 2

[0017] Embodiment 2: preparation 20% matrine·tea saponin microemulsion

[0018] The weight percent (%) of insecticidal active ingredients is: matrine 5.0, tea saponin 15.0;

[0019] The weight percent (%) of each component of auxiliary agent is: emulsifier: polyoxyethylene alkylamine is 10.0; Solvent: Solvesso100 is 15.0; Cosolvent: N-methylpyrrolidone is 5.0; Measure deionized water.

[0020] Dissolve matrine in the solvent according to the ratio, dissolve tea saponin in water, add the emulsifier into the matrine solution, stir well, add other additives, tea saponin aqueous solution, and put it into the homogenizer Be vigorously mixed and homogenized.

Embodiment 3

[0021] Embodiment 3: preparation 10.5% matrine·tea saponin aqueous emulsion

[0022] The weight percent (%) of insecticidal active ingredients is: matrine 3.5, tea saponin 7.0;

[0023] The weight percentage (%) of each component of the auxiliary agent is: emulsifier: lignosulfonate is 5.0; thickener: gum arabic is 2.0, xanthan gum is 1.0; solvent: S-200 is 10.0; antifreeze: sorbic acid 5.0; defoaming agent: high-efficiency polysiloxane is 0.2; preservative: potassium sorbate is 2.0; the balance is deionized water.

[0024] Dissolve matrine and tea saponin in the solvent according to the ratio, add emulsifier and co-solvent into the matrine and tea saponin solution, stir well, slowly add the above mixture into water, and stir thoroughly to get the product .

Abstract

Belonging to the technical field of pesticides, the invention relates to an insecticidal and bactericidal synergistic composition containing a natural pesticide matrine and a natural surfactant tea saponin. The composition is characterized in that, tea saponin as one of the active components in the pesticide synergistic composition changes its traditional identity simply as a surfactant research object, and in combination with matrine, tea saponin plays a synergistic insecticidal and bactericidal role of botanical active components with matrine. Matrine and tea saponin, in a mass ratio of 50:1-1:1000, reaches synergetic and spread spectrum effects in the composition of the invention. Thus, the composition in the invention can be used for control of a plurality of insect diseases in agricultural and horticultural crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and is characterized in that it relates to a pesticide synergistic composition, in particular to the preparation and application of a synergistic pesticide composition containing matrine and tea saponin. Background technique [0002] The plant-derived pesticide matrine (Matrine) has low toxicity to humans and animals, is safe to use, has no residue, and has stomach toxicity and contact killing effects; it directly acts on multiple targets of the worm body, paralyzes the nerve center, and then coagulates the protein of the worm body, blocking Dead pores, suffocation and death; can destroy the resistance system of pests, and have no cross-resistance with other pesticides, effectively avoiding the problem of resistance to conventional products. However, matrine botanical pesticides also have their own disadvantages: first, the complex structure of the compound makes it difficult to synthesize; se...
