Problems solved by technology

Therefore, neonicotinoid insecticides are widely used in the market and used in a large amount, but with the increasing frequency and amount of use, it will induce pest resistance, shorten the service life, cause pesticide residues and environmental pollution, etc.
At present, there is no report on the combination of the above three and its application

example 1

[0022] An insecticidal composition for controlling piercing-sucking mouthparts pests, the preparation of the insecticidal composition is a suspension concentrate. Made of the following components by weight percentage: Thiamethoxam 10%, Buprofezin 5%, Chlorpyrifos 15%, Dispersant polycarboxylate 2%-5%, Wetting agent Sodium dodecylbenzene sulfonate 2% % to 5%, structure regulator xanthan gum 0.5%, antifreeze agent ethylene glycol 4%, defoamer silicone compound 0.1%, water to make up to 100%.

[0023] Mix the dispersant, wetting agent, defoamer, structure regulator, and antifreeze in the above formula evenly through high-speed shearing, add thiamethoxam, buprofezin, and chlorpyrifos and mill in a ball mill for 2 to 3 hours to make the fine particles The diameters are all below 5 μm to obtain the suspension product of the present invention.

Embodiment 1

[0024] The insecticidal composition described in Example 1 for controlling piercing-sucking mouthparts has a co-toxicity coefficient of 178.69 measured in the toxicity test against alfalfa aphids.

example 2

[0026] An insecticidal composition for controlling piercing-sucking mouthparts pests, the preparation of the insecticidal composition is a wettable powder. It is made of the following components by weight percentage: thiamethoxam 5%, buprofezin 5%, chlorpyrifos 15%, dispersant sodium lignosulfonate 3%-5%, wetting agent pull-off powder 7%-10% , The filler is supplemented to 100%, and the filler is made of diatomaceous earth, white carbon black, etc.

[0027] Weigh the thiamethoxam, buprofezin, chlorpyrifos, dispersant, wetting agent and filler in the above formula by weight, mix them uniformly in a mixing tank, pulverize them with a jet mill and then mix them uniformly to prepare Obtain the wettable powder product of the present invention.

Abstract

The invention belongs to the technical field of pesticides, and particularly relates to an insecticide composition for preventing and controlling piercing-sucking mouthpart pests, and application of the insecticide composition. The insecticide composition for preventing and controlling the piercing-sucking mouthpart pests comprises active ingredients of thiamethoxam, buprofezin and chlorpyrifos; the active ingredients account for 5-40% of the total weight of the insecticide composition; and the weight percentage of thiamethoxam to buprofezin to chlorpyrifos is (1-5):(1-5):(2-7). The insecticide composition is used for preventing and controlling aphid, aleyrodid, leafhoppers and thrips.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition for preventing and treating piercing-sucking mouthparts pests and an application thereof. Background technique [0002] Thiamethoxam, English common name thiamethoxam, chemical name 3-(2-chloro-5thiazolylmethyl)-5-methyl-N-nitro-4H-1,3,5-tetrahydro. Thiamethoxam belongs to the second generation of neonicotinoid insecticides. Its mechanism of action is to inhibit the nicotinic acid acetylcholinesterase receptor in the central nervous system of insects, thereby blocking the normal conduction of the central nervous system of insects, resulting in paralysis and death of insects. Thiamethoxam has contact killing, stomach poisoning and systemic effects on pests. It has high activity on Homoptera and Thysanoptera, rapid drug effect and long-lasting effect. However, due to years of unreasonable use, pests have developed resistance to it , so th...
