Problems solved by technology

[0005] Fipronil and butylene Fipronil are highly active against subterranean pests, but single-dose use is easy to produce resistance, and fipronil and butylene fipronil are used alone for the control of subterranean pests, and the effect on cutworms is poor And the cost of prevention is high

Embodiment 1

[0015] Example 1: 40.5% tefluthrin·fipronil wettable powder (tefluthrin: fipronil=80:1)

[0016] Tefluthrin 42.11g, fipronil 0.56g, sodium lignosulfonate (wetting agent) 3g, NNO (dispersant) 5g, pull-off powder (dispersant) 0.5g, kaolin make up to 100g.

[0017] The active ingredients, various additives and fillers are fully mixed in proportion, and then pulverized by a superfine pulverizer to obtain a wettable powder.

Embodiment 2

[0018] Example 2: 61% tefluthrin·butene-fipronil water-dispersible granules (tefluthrin:butene-fipronil=60:1)

[0019] Tefluthrin 62.11g, butylene fipronil 1.04g, NNO (dispersant) 5g, sodium lignosulfonate (dispersant) 5g, sodium lauryl sulfate (wetting agent) 2g, aluminum magnesium silicate (Disintegrant) 2g, diatomaceous earth supplemented to 100g.

[0020] The active ingredients, additives and fillers are uniformly mixed according to the proportion of the formula, crushed into a wettable powder by airflow, and then a certain amount of water is added to mix and extrude to granulate, and the water-dispersible granule product is obtained after drying and sieving.

Embodiment 3

[0021] Example 3: 21% tefluthrin·fipronil suspension concentrate (tefluthrin: fipronil=20:1)

[0022] Tefluthrin 21.06g, fipronil 1.11g, sodium lignosulfonate (dispersant) 4g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 3g, silicone oil (defoamer) 0.4g , supplemented with deionized water to 100g.

[0023] Active ingredient, dispersant, wetting agent, thickener, water and other components are uniformly mixed according to the proportion of the formula, and the suspending agent is obtained after high-speed shearing.

Abstract

The invention discloses an insecticide composition. The insecticide composition contains two effective constituents A and B, wherein, A is tefluthrin and B is either fipronil or butene-fipronil. The mass ratio of the A to the B is 80:1-1:40. The combination of the A to the B produces obvious synergism, which can reduce use amount of the effective constituents and the number of pesticide application. The insecticide composition can be applied to control various soil insects in agriculture, especially such soil insects as wireworms, scarab, black cutworms and the like.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing tefluthrin, and the application of the composition in the control of agricultural pests. Background technique [0002] Tefluthrin, a pyrethroid insecticide, is a soil insecticide that can well control Coleoptera, Lepidoptera and some Diptera pests that inhabit the soil. It can prevent and control soil arthropods in a broad spectrum, including pumpkin twelve-star beetle, needleworm, flea beetle, scarab, beet hidden food beetle, cutworm, corn borer, Swedish straw fly, etc. [0003] Fipronil is a phenylpyrazole insecticide with a broad insecticidal spectrum. It mainly has stomach poisoning effect on pests, and has both contact and certain systemic effects. The agent can be applied to the soil or sprayed on the leaves. Applying to the soil can effectively control corn root leaf beetle, wireworm and cutworm. [0004] Butylene fipronil is a phenyl...
