Embodiment 1

[0021] Embodiment 1: the insecticidal composition is a suspending agent, and the percentages of each component are respectively:

[0022]

[0023] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredients A and B, and grind in a ball mill for 2-3 hours, so that the particle diameter is below 5mm. Prepare the suspension formulation of the insecticidal composition of the present invention.

Embodiment 2

[0024] Embodiment 2: the insecticidal composition is an emulsion in water, and the percentages of each component are respectively:

[0025]

[0026] 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

[0027] Embodiment 3: the insecticidal composition is a microemulsion, and the percentages of each component are respectively:

[0028]

[0029] 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 . Embodiment 4: the insecticidal composition is a wettable powder, and the percentages of each component are respectively:

[0030]

[0031] The specific operation steps are: mix active ingredients A and B, other additives and fillers, fully stir in a stirring tank, pulverize through a jet mill, and mix evenly to obtain the wettable powder preparation of the insecticidal composition of the present invention.

Abstract

The invention discloses an insecticidal composition containing methoxyfenozide and efficient cyfluthrin. The insecticidal composition comprises a first active ingredient methoxyfenozide, a second active ingredient efficient cyfluthrin and common auxiliary components, wherein the weight ratio of methoxyfenozide to efficient cyfluthrin in the insecticidal composition is (40:1)-(1:40). A large number of indoor and outdoor tests indicate that the insecticidal composition has an obvious synergistic effect and realizes a relatively good prevention effect on the lepidoptera pests on crops such as rice-stem borer, tryporyza incertulas, rice leaf roller, cotton bollworm, apple skin worm, vegetable prodenia litura, beet armyworm, plutella xylostella, cabbage caterpillar and the like; meanwhile, in practical application, the application amount of pesticides is reduced, pesticide residues on the crops are lowered, the environmental pollution is reduced, and the generation of drug resistance of the pests is delayed.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition using methoxyfenozide and beta-cyfluthrin as active ingredients, which is applied to the control of Lepidoptera pests on crops. Background technique [0002] The problem of pesticide resistance of agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical control of pests year after year, the increase in the use of pesticides and the unscientific use of pesticides and other factors, the resistance of pests is becoming more and more serious, and the types of resistant pests are increasing. At the same time, the high-intensity use of pesticides has led to a series of problems such as excessive pesticide residues in agricultural products, environmental pollution, and increased pesticide costs for farmers, which is not co...
