Embodiment 1

[0018] Example 1: 61% tefluthrin·acetamiprid water dispersible granules (tefluthrin: acetamiprid=60:1)

[0019] Tefluthrin 63.17g, acetamiprid 1.04g, NNO (dispersant) 5g, sodium lignosulfonate (dispersant) 5g, sodium lauryl sulfate (wetting agent) 2g, magnesium aluminum silicate (disintegration agent) Solution) 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 2

[0021] Example 2: 41% tefluthrin·thiamethoxam wettable powder (tefluthrin:thiamethoxam=40:1)

[0022] Tefluthrin 42.11g, thiamethoxam 0.51g, sodium lignosulfonate (wetting agent) 3g, NNO (dispersant) 5g, pull-off powder (dispersant) 0.5g, kaolin to make up to 100g.

[0023] 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

[0024] Example 3: 21% tefluthrin·acetamiprid oil suspension concentrate (tefluthrin: acetamiprid=20:1)

[0025] Tefluthrin 21.06g, acetamiprid 1.04g, sodium lignosulfonate (wetting and dispersing agent) 10g, phenethylphenol polyoxyethylene ether (emulsifier) ​​5%, bentonite (thickener) 5g, organic Silicone (defoamer) 5g, castor oil to make up to 100g.

[0026] Mix active ingredients, dispersants, emulsifiers, stabilizers, defoamers, solvents and other components according to the ratio of the formula, put them into a sand mill and grind them, then put them into a homogeneous mixer and mix them to get the finished product.

Abstract

The invention discloses an insecticidal composition which comprises an active substance A and an active substance B which are used as effective components, wherein A is tefluthrin, B is one of neonicotine insecticides comprising acetaniprid, imidacloprid and thiamethoxam, and the mass ratio of A to B is 60:1-1:80. The composition of the invention has obvious synergy, can lower the consumption of the effective components and reduce the insecticide applying times, is used for controlling various agricultural pests, and is especially suitable for controlling scarab larvae, flea beetle larvae androot-knot nematode.

Description

technical field [0001] The invention relates to a pesticide composition with synergistic effect, specifically a pesticide composition containing tefluthrin, and the application of the composition in the control of agricultural subterranean pests. Background technique [0002] Tefluthrin, a pyrethroid insecticide, is a soil insecticide that can broadly control soil arthropods, including needleworms, flea beetles, scarabs, cutworms, corn borers, and Swedish straw fly etc. Since tefluthrin kills pests through the action of steam, the duration of tefluthrin and the performance of the agent are greatly affected by the physical and chemical properties of the soil. [0003] Acetamiprid, acetamiprid is a new type of high-efficiency neonicotinoid insecticide, in addition to super strong contact, stomach toxicity, strong penetration, strong systemic, less dosage, good quick-acting, long-lasting Features such as long validity period. [0004] Imidacloprid, a new generation of chlori...
