Problems solved by technology

[0006] Organophosphorus insecticides are widely used in the control of underground pests, but organophosphorus insecticides kill pests through contact and stomach poisoning, so the requirements for uniformity of application are high, and it is easy to cause problems due to uneven application. Unsatisfactory control effect due to uniformity

Embodiment 1

[0017] Example 1: 81% tefluthrin·chlorpyrifos water dispersible granule (tefluthrin:chlorpyrifos=80:1)

[0018] Tefluthrin 84.21g, chlorpyrifos 1.05g, NNO (dispersant) 5g, sodium lignosulfonate (dispersant) 5g, sodium lauryl sulfate (wetting agent) 2g, aluminum magnesium silicate (disintegrant) ) 2g, diatomaceous earth supplemented to 100g.

[0019] The active ingredients tefluthrin and chlorpyrifos, additives and fillers are mixed evenly according to the proportion of the formula, crushed into a wettable powder by airflow, and then mixed with a certain amount of water to extrude and granulate, and then dried and screened to obtain a water dispersion Sexual granule products.

Embodiment 2

[0020] Example 2: 41% tefluthrin · phoxim wettable powder (tefluthrin: phoxim = 40: 1)

[0021] Tefluthrin 42.11g, phoxim 1.11g, sodium lignosulfonate (wetting agent) 3g, NNO (dispersant) 5g, pull-off powder (dispersant) 0.5g, kaolin make up to 100g.

[0022] The active ingredients tefluthrin and phoxim, various additives and fillers are fully mixed in proportion, and then pulverized by an ultrafine pulverizer to obtain a wettable powder.

Embodiment 3

[0023] Example 3: 21% tefluthrin·diazinon suspension concentrate (tefluthrin:diazinon=20:1)

[0024] Tefluthrin 21.06g, diazinon 1.05g, sodium lignosulfonate (dispersant) 4g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 3g, silicone oil (defoamer) 0.4g , supplemented with deionized water to 100g.

Abstract

The invention discloses an insecticidal composition with a synergy effect. Active ingredients of the composition has two active substances of A and B, wherein A is tefluthrin; and B is one of organophosphorus insecticides such as chlorpyrifos, phoxim and diazinon. The mass ratio of A to B is 80:1-1:80. The compound of A and B has the obvious synergy effect, can reduce component usage and reduce application times of the insecticide. The composition of the invention can be used for preventing and controlling various soil insects in agriculture, and is particularly suitable for preventing and controlling wire worms, larva of cockchafers and black cutworms.

Description

technical field [0001] The invention relates to an insecticidal composition with synergistic effect, in particular to a pesticide composition containing tefluthrin, and the application of the composition in the control of agricultural pests. Background technique [0002] Tefluthrin, a pyrethroid soil insecticide, can well control Coleoptera and Lepidoptera and Diptera pests that inhabit the soil. Insecticide in soil works by steam rather than by contact. 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. However, single-dose use of tefluthrin is prone to resistance, and the cost of control is high. [0003] Chlorpyrifos (Chlorpyrifos), chlorpyrifos is an organophosphate insecticide and acaricide. It has a wide insecticidal spectrum and has contact killing, stomach poisoning and fumigation effects. The residual period on...
