Embodiment 1

[0015] Example 1: 41% tefluthrin·abamectin water dispersible granules (tefluthrin:abamectin=40:1)

[0016] Tefluthrin 42.11g, Abamectin 1.09g, NNO (dispersant) 5g, sodium lignosulfonate (dispersant) 5g, sodium lauryl sulfate (wetting agent) 2g, aluminum magnesium silicate ( disintegrant) 2g, diatomaceous earth supplemented to 100g.

[0017] 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 2

[0018] Example 2: 21% Tefluthrin · Thiazophosphine WP (Teffluthrin: Thiazophosphine=20:1)

[0019] Tefluthrin 21.06g, thiazophosphine 1.08g, sodium lignosulfonate (wetting agent) 3g, NNO (dispersant) 5g, pull-off powder (dispersant) 0.5g, kaolin make up to 100g.

[0020] 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 3

[0021] Example 3: 11% tefluthrin·abamectin suspension (tefluthrin:abamectin=10:1)

[0022] Tefluthrin 10.53g, avermectin 1.09g, sodium lignosulfonate (dispersant) 4g, ethylene glycol (antifreeze) 4g, bentonite (thickener) 3g, silicone oil (defoamer) 0.4 g, replenished to 100g with deionized water.

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

Abstract

The invention discloses tefluthrin-containing combination which contains A active ingredient and B active ingredient, wherein the A active ingredient is tefluthrin and the B active ingredient is avermectin or fosthiazate. The weight ratio of the A active ingredient to the B active ingredient is 40:1-1:20. The combination has obvious synergistic effect and can reduce the dosage of the active ingredients and the pesticide application time. The combination is applicable for prevention and control of various agricultural pests and nematodes.

Description

technical field [0001] The invention relates to an insecticidal and nematicideicidal composition, in particular to a 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. Tefluthrin works against insects in soil through vapor rather than contact. It can control soil arthropods in a broad spectrum, including needleworms, flea beetles, scarabs, beet-eating beetles, cutworms, etc. [0003] Avermectins have contact and stomach poisoning effects on insects and mites and have weak fumigation effects, without systemic effects. However, it has a strong penetrating effect on the leaves, can kill pests under the epidermis, and has a long residual effect, and has a good poisoning effect on nematodes. [0004] Fosthiazate, a nematicide, has contact...
