Embodiment 1

[0020] Embodiment 1: the insecticidal composition is a suspending agent, and the percentages of each component are respectively:

[0021]

[0022] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredients A, B, and C, 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 obtained.

Embodiment 2

[0023] Embodiment 2: the insecticidal composition is an emulsion in water, and the percentages of each component are respectively:

[0024]

[0025]

[0026] The specific operation steps are as follows: firstly, the active ingredients A, B, C, solvent, and 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, B, and C with a solvent and a co-solvent, then add other auxiliaries, 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 an insecticidal composition containing Polygonum hydropiper. The effective components include metaflumizone, 1,2-dibenzoyl-1-tert-butylhydrazine and a Polygonum hydropiper extractive solution at a weight ratio of 1:1:1. The insecticidal composition of the invention has a synergic effect, and has an excellent control effect on Lepidoptera pests in fruit trees, vegetables, cotton and rice.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition containing Polygonum hydroponica. Background technique [0002] Metaflumizone belongs to semicarbazone insecticides. Its 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 cause excessive relaxation and paralysis of insects. After a few 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, and cicadas. It has no neurotoxicity to mammals, low acute toxicity to birds, and low risk to bees. Because it can rapidly hydrolyze and photolyze in water, ...
