Embodiment 1

[0019] Embodiment 1: the insecticidal composition is a suspending agent, and the percentages of each component are respectively: Active ingredient A + B 1~80%, dispersant 5~20%, antifreeze agent 1~5%, thickener 0.1~2%, defoamer 0.1~0.5%, pH regulator 0.1~5%, the rest Measure water.

[0020] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredients A and B, grind in a ball mill for 2 to 3 hours, so that the particle diameter is below 5mm, and then Prepare the suspension formulation of the insecticidal composition of the present invention.

Embodiment 2

[0021] Embodiment 2: the insecticidal composition is an emulsion in water, and the percentages of each component are respectively: Active ingredient A+B 1~80%, emulsifier 2~30%, solvent 5~15%, stabilizer 2~15%, antifreeze 2~5%, defoamer 0.1~8%, thickener 0.1~ 2%, balance water.

[0022] The specific operation steps are as follows: the active ingredients A and B, a solvent and an emulsifier are mixed together to dissolve into a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reactor, slowly add water until reaching the phase inversion point, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain the insecticidal combination of the present invention water emulsion formulations.

Embodiment 3

[0023] Embodiment 3: the insecticidal composition is a microemulsion, and the percentages of each component are respectively: Active ingredient A+B 1-80%, emulsifier 10-30%, antifreeze 1-10%, stabilizer 0.5-10%, solvent and co-solvent 20-45%, the balance water.

[0024] The specific operation steps are: completely dissolve the active ingredients A and B with a solvent and a co-solvent, then add other adjuvants, mix well, finally add water, and after fully stirring, the microemulsion preparation of the insecticidal composition of the present invention can be obtained .

Abstract

The invention discloses an insecticidal composition of indoxacarb and cartap. The insecticidal composition comprises first active ingredient indoxacarb and second active ingredient cartap as well as common helper components, wherein the weight ratio of the indoxacarb to the cartap is 40:1-1:40. a large amount of indoor and outdoor experiments show that the compounded insecticidal composition has a synergetic effect and has excellent preventing and treating effects on various lepidoptera pests, such as plutella xylostella, cabbage caterpillar, asparagus caterpillar, prodenia litura, cotton bollworms, rice stem borers, yellow rice borers and rice leaf rollers, on crops such as vegetables, cottons and rices.

Description

technical field [0001] The present invention relates to a pesticide insecticidal composition and its application field, specifically a binary compound compounded with indoxacarb and cartap as active ingredients, which is mainly applied to various scales on vegetables, cotton, rice and other crops. Control of winged pests. Background technique [0002] Indoxacarb, English common name: indoxacarb, is a broad-spectrum oxadiazine insecticide with stomach toxicity and contact action. The main mechanism of action is to block the sodium ion channel in the nerve cells of the pest, resulting in poor coordination, paralysis and eventually death of the target pest. It has the characteristics of high efficiency, high selectivity and low residue. No cross-resistance with other insecticides. It can effectively control various pests on grain, cotton, fruit trees, vegetables and other crops. [0003] Cartap, the English common name cartap, is a nereistin insecticide with strong contact,...
