Problems solved by technology

At present, the control effect on other types of pests such as aphids and leafhoppers is not obvious. If a single agent is used, it will inevitably increase the dosage and increase the cost of control.

Embodiment 1

[0030] A novel pesticide composition is prepared by the following method: take 0.0105g rotenone 95% original drug (i.e. 10mg rotenone), dissolve it with 0.5mL DMF, add 0.2mL Tween-80 emulsifier, stir evenly, add 99.3 mL water, made into 100mg / L rotenone mother solution;

[0031] Weigh 0.0105g of methoxyfenozide 95% original drug (i.e. 10mg of methoxyfenozide mother solution), dissolve it in 0.5mL of DMF, add 0.2mL of Tween-80 emulsifier, stir evenly, add 99.3mL of clear water, and prepare Become methoxyfenozide mother liquor of 100mg / L;

[0032] Measure and mix 0.3 mL of rotenone mother liquor and 9.7 mL of methoxyfenozide mother liquor respectively, add water containing 0.1% Tween-80 emulsifier to 100 mL, and obtain the product.

Embodiment 2

[0034] A novel pesticide composition is prepared by the following method: take 0.0105g rotenone 95% original drug (i.e. 10mg rotenone), dissolve it with 0.5mL DMF, add 0.2mL Tween-80 emulsifier, stir evenly, add 99.3 mL water, made into 100mg / L rotenone mother solution;

[0035] Weigh 0.0105g of methoxyfenozide 95% original drug (i.e. 10mg of methoxyfenozide mother solution), dissolve it in 0.5mL of DMF, add 0.2mL of Tween-80 emulsifier, stir evenly, add 99.3mL of clear water, and prepare Become methoxyfenozide mother liquor of 100mg / L;

[0036] Measure and mix 0.4 mL of rotenone mother liquor and 9.6 mL of methoxyfenozide mother liquor respectively, add water containing 0.1% Tween-80 emulsifier to 100 mL, and obtain the product.

Embodiment 3

[0038] A novel pesticide composition is prepared by the following method: take 0.0105g rotenone 95% original drug (i.e. 10mg rotenone), dissolve it with 0.5mL DMF, add 0.2mL Tween-80 emulsifier, stir evenly, add 99.3 mL water, made into 100mg / L rotenone mother solution;

[0039] Weigh 0.0105g of methoxyfenozide 95% original drug (i.e. 10mg of methoxyfenozide mother solution), dissolve it in 0.5mL of DMF, add 0.2mL of Tween-80 emulsifier, stir evenly, add 99.3mL of clear water, and prepare Become methoxyfenozide mother liquor of 100mg / L;

[0040] Measure and mix 0.5 mL of rotenone mother liquor and 9.5 mL of methoxyfenozide mother liquor respectively, add water containing 0.1% Tween-80 emulsifier to 100 mL, and obtain the product.

Abstract

The invention relates to a novel pesticide composition. The novel pesticide composition comprises, by volume, 55% to 99.8% of an aqueous solution with emulsifier with the mass percentage of 0.1%, 0.1% to 10% of rotenone mother liquor, and 0.1% to 35% of methoxyfenozide mother liquor. The preparation method of the pesticide composition comprises the steps that first, the rotenone mother liquor is obtained; second, the methoxyfenozide mother liquor is obtained; third, mixed liquor is prepared; fourth, the product is prepared. The pesticide composition has the synergistic effect; moreover, because the insecticidal spectrum of pesticides is expanded due to the pesticide composition, pest resistance to insecticide is eliminated or delayed, the prevention and control cost is reduced, the degree of environmental friendliness is improved, and integrated control of pests is better facilitated; the preparation method is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a novel pesticide composition and a preparation method thereof. Background technique [0002] The chemical name of Rotenone is: [2R-(2aα,6aα,12aα)-1,2,12a-tetrahydro-8,9-dimethoxy-2-(1-methylvinyl)[1] Benzopyran[3,4-b]furoyl[2,3-h][1]benzopyran-6(6aH)-one belongs to a colorless, odorless, ketone crystalline compound, is a A natural insecticide. In terms of toxicology, it is a highly specific substance, especially for aphids, cabbage butterflies and diamondback moths, which have strong contact and stomach poisoning effects. Studies have shown that the mechanism of action of rotenone is to affect the respiration of insects, and it mainly interacts with a certain component between NADH dehydrogenase and coenzyme Q. The electron transport chain of the pest cells is inhibited, thereby reducing the ATP level in the organism, and finally the pests cannot get energy supply, and then slow dow...
