Embodiment 1

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

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

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) 5-80%, emulsifier 5-30%, solvent 5-15%, stabilizer 3-15%, antifreeze 2-5%, defoamer 0.2-8%, thickener 0.2~2%, the balance is water.

[0022] The specific operation steps are as follows: firstly, the active ingredient A and the active ingredient B, a solvent and an emulsifier are mixed together, and dissolved to form 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) 5-80%, emulsifier 10-30%, antifreeze 2-10%, stabilizer 1-10%, solvent and co-solvent 25-50%, the balance water.

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

Abstract

The invention relates to a pesticide composition of metaflumizone and chromafenozide. The effective components of the pesticide composition are metaflumizone and chromafenozide, and the weight ratio of metaflumizone to chromafenozide is (30 to 1) to (1 to 20). A large amount of indoor and outdoor tests show that the pesticide composition after metaflumizone and chromafenozide are compounded has a synergistic effect and a good effect for preventing and controlling various lepidoptera pests on fruit trees, vegetables, cotton and paddy rice.

Description

technical field [0001] The present invention relates to a pesticide insecticidal composition and its application field, specifically, a binary compound compounded with metaflumizone and fenfenozide as active ingredients, which is mainly applied to fruit trees, vegetables, cotton, rice, etc. Control of Lepidoptera pests. Background technique [0002] Metaflumizone (metaflumizone): belongs to the semicarbazone insecticides, the main mechanism of action is that it attaches to the receptors of sodium ion channels, hinders the passage of sodium ions, and then inhibits nerve impulses to make the insect body excessively relaxed and paralyzed, almost After hours, the pests stop feeding and die within 1 to 3 days. The medicament mainly kills pests by gastric poisoning, with little contact effect and no systemic effect. It can effectively control various Lepidoptera pests and certain Coleoptera larvae and adults, and can also be used to control pests such as ants, termites, flies, a...
