Embodiment 1

[0022] Embodiment 1: preparation 5.5% matrine · spirotetramat microemulsion

[0023] The weight percentage (%) of insecticidal active ingredients is: matrine 5.0, spirotetramat 0.5;

[0024] The weight percentage (%) of each component of the auxiliary agent is: emulsifier: polyoxyethylene alkylamine 20.0; cosolvent: ethyl acetate 0.05; defoamer: high-efficiency polysiloxane 0.1-1.0; ; Solvent: Solvesso100 20.0; The remainder is deionized water.

[0025] Dissolve matrine and spirotetramat in the solvent according to the ratio, add the emulsifier into the matrine-spirotetramat solution, stir well, add deionized water and other additives, and put it into the homogenizer Intensely mixed and homogenized.

Embodiment 2

[0026] Embodiment 2: preparation 5.1% matrine · spirotetramat water emulsion

[0027] The weight percentage (%) of insecticidal active ingredients is: matrine 5.0, spirotetramat 0.1;

[0028] The weight percentage (%) of each component of the auxiliary agent is: emulsifier: sodium naphthalenesulfonate formaldehyde condensate (NNO) 8.0; solvent: S-15010.0; thickener: xanthan gum 0.2, aluminum magnesium silicate 1.0; defoamer : EO-PO polymer 0.3%; preservative: sodium benzoate 0.8%; antifreeze: ethylene glycol 6.0; the balance deionized water.

[0029] Dissolve matrine and spirotetramat raw materials in the solvent according to the ratio, add emulsifier and co-solvent into the matrine and spirotetramat solution, stir well, slowly add the above mixture into water, and stir well Instantly.

Embodiment 3

[0030] Embodiment 3: preparation 33% matrine spirodiclofen suspension concentrate

[0031] The weight percent (%) of insecticidal active ingredients is: matrine 30.0, spirodiclofen 3.0;

[0032] The weight percentage (%) of each component of the auxiliary agent is: wetting and dispersing agent: NNO 2.0, D4251.5, Nongru 0201B 2.5; defoamer: organic silicone 1.0; antifreeze: propylene glycol 5; preservative: paraformaldehyde 0.7 ; Thickener: xanthan gum 0.1, white carbon black 1.0; balance deionized water.

[0033] Grind matrine and spirodiclofen raw materials according to the ratio, add various additives and water except thickeners, put them into a high-shear emulsifier and mix them evenly, add thickeners and mix them evenly. Grinding with a sander, it can be obtained after passing the microscope inspection.

Abstract

The invention belongs to the pesticide technology field, and relates to a synergy composition for matrine and tetronic acid pesticides. The mass ratio of matrine to tetronic acid is 50:1-1:50. The matrine in the composition comprises matrine, oxymatrine and a mixture of matrine and oxymatrine, or a series alkaloid extract and its preparation obtained from plants such as radix sophorae flavescentis, Sophora alopecuroides and Subprostrate Sophora Root. The tetronic acid pesticide can be one of spirotetramat, spirodiclofen and spirotetramat or its combination. The composition of the invention is capable of generating cooperation and synergy effects, overcoming harmful biological drug resistance, prolonging the service life of the pesticide, and enlarging the prevention and cure scope, can be used for preventing and treating a plurality of insect diseases on agriculture and gardening crops, especially suitable for insects possessing drug resistance on single pesticide, such as aphid, scale insect, leaf mites, leafhopper, planthopper or whitefly and thrips.

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 composition containing matrine and tetronic acid pesticides. Background technique [0002] The problem often faced in pest control is: how to reduce the dosage of active ingredients in pesticides to reduce or avoid adverse environmental or toxic effects, while still effectively controlling agricultural pests. Second, avoid frequent and single use of a certain pesticide variety, so as not to cause rapid selection of resistant pests or pathogens. In the pesticide compound preparation characterized by synergism, spectrum expansion, and combined treatment, insecticides with synergistic effects and different mechanisms of action are used for compounding, which can not only reduce the dose of each active ingredient, but also be used for resistance.
