AI Technical Summary

Problems solved by technology

It can effectively control pests of Lepidoptera, Diptera and Thysanoptera, and can also control some pest species in Coleoptera and Orthoptera that eat a lot of leaves, and control of piercing-sucking pests and mites less effective
It is relatively safe for predatory natural enemy insects. Due to the unique mechanism of insecticidal action, no reports of cross-resistance with other insecticides have been found so far.

Embodiment 1

[0041] Embodiment 1: the weight proportion of each component of suspension type insecticide composition

[0042] components weight percentage weight percentage weight percentage spinosad 1％ 5％ 4％ Metaflumizone 9％ 5％ 6％ BJ-05 5％ 6％ 8％ ethanol 5％ 3％ 7％ 2201 11％ 10％ 18％ urea 7％ 5％ 8％ Rheolate 210 0.5％ 0.3％ 0.4％ Deionized water Top up to 100% Top up to 100% Top up to 100%

[0043] Preparation method: According to the designed formula, add the weighed original drug, emulsifier, wetting agent, thickener and water into the sand mill cylinder, stir evenly, disperse for 30 minutes under high-speed stirring, and stop the pre-dispersion. Add sanding media (glass beads) and defoamer, start the motor, and start sanding. After 2 to 4 hours, stop sanding, filter, remove glass beads, add other additives, antifreeze and stabilizer for preparation, and obtain a suspension.

Abstract

The invention relates to an insecticide composition, in particular to an insecticide composition which comprises synergetic effective doses of metaflumizone and spinosad, wherein the weight ratio of the metaflumizone to the spinosad is preferentially 1:1-1:9, more preferentially 1:1. The composition can be prepared into suspension type, emulsifier type and water dispersible granule type, the control spectrum can be greatly expanded, the control efficiency can be improved, moreover, the cost can be saved, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to a synergistic insecticide composition, in particular to a synergistic insecticide composition comprising metaflumizone and spinosyn. Background technique [0002] Metaflumizone (metaflumizone) is a new compound pesticide, which belongs to semicarbazone insecticides. Metaflumizone has obvious control effects on chewing and biting insect species Lepidoptera and Coleoptera, such as common species include rice leaf borer, beet armyworm, cotton bollworm, cotton pink bollworm, cabbage butterfly, cabbage Noctuid moth, diamondback moth, cabbage borer, cutworm, rice stem borer, etc. have moderate control effects on leaf tortrix; metaflumizone has good control effect on coleopteran leaf beetle such as potato leaf beetle. The control of flea beetles and seed weevils is moderate; metaflumizone has no activity against Thysanthera, mites and nematodes. The drug has great potential in controlling non-crop pests such as ants, termites, fire ...
