Embodiment 1

[0014] Weigh 5% chlorpyrifos, 5% thiamethoxam, 5% lignosulfonate, 4% NO, 10% white carbon black, and diatomaceous earth to add up to 100% by weight. 10% chlorpyrifos·thiamethoxam granules are prepared from the above-mentioned raw materials through the conventional steps of pulverizing, mixing and granulating for preparing granules.

[0015] In the present embodiment, the weight ratio of chlorpyrifos to thiamethoxam can be changed between 0.01~100:1 (for example 0.01:1, 0.5:1, 5:1, 10:1, 90:1, 100:1). Or total weight composition is still 10%, forms new embodiment.

[0016] It is also possible to replace thiamethoxam with nitenpyram to form a new embodiment.

[0017] It is also possible to replace chlorpyrifos with triazophos or chlorazophos to form a new embodiment.

Embodiment 2

[0019] Weigh 28.5% chlorpyrifos, 1.5% thiamethoxam, 5% special emulsifier, and add enough toluene to 100% by weight. Stir and dissolve until uniformly mixed to obtain 30% chlorpyrifos·thiamethoxam emulsifiable concentrate.

[0020] In the present embodiment, the weight ratio of chlorpyrifos to thiamethoxam can be changed between 0.01~100:1 (for example 0.01:1, 0.5:1, 5:1, 10:1, 90:1, 100:1). Or total weight composition is still 30%, forms new embodiment.

[0021] It is also possible to replace thiamethoxam with nitenpyram to form a new embodiment.

[0022] It is also possible to replace chlorpyrifos with triazophos or chlorazophos to form a new embodiment.

Embodiment 3

[0024] Weigh 10% chlorpyrifos, 40% thiamethoxam, 8% dispersant, 4% wetting agent, 2% white carbon black, and diatomaceous earth to add up to 100% by weight. 50% chlorpyrifos·thiamethoxam water-dispersible granules are prepared from the above-mentioned raw materials through the steps of superfine pulverization, mixing and granulation for conventional preparation of granules.

[0025] In the present embodiment, the weight ratio of chlorpyrifos to thiamethoxam can be changed between 0.01~100:1 (for example 0.01:1, 0.5:1, 5:1, 10:1, 90:1, 100:1). Or total weight composition is still 50%, forms new embodiment.

[0026] It is also possible to replace thiamethoxam with nitenpyram to form a new embodiment.

[0027] It is also possible to replace chlorpyrifos with triazophos or chlorazophos to form a new embodiment.

Abstract

The present invention relates to pesticide composition comprising the first active component of organophosphate pesticide and the second active component of neonicotine pesticide in the weight ratio of 0.01-200, preferably 0.01-100. The organophosphate pesticide is chlorpyrifos, triazophos or isazofhos; and the neonicotine pesticide is thiamethoxam or nitenpyram. The present invention also discloses the preparation process of the pesticide composition and its use in controlling homoptera pests.

Description

technical field [0001] The invention relates to an insecticide composition, especially an insecticide composition comprising a heterocyclic organophosphorus insecticide and a neonicotinoid insecticide. Background technique [0002] Organophosphorus insecticides containing heterocycles are broad-spectrum insecticides and acaricides, and their main products are chlorpyrifos, triazophos, chlorazophos, etc. One of the most widely used varieties at present is chlorpyrifos, its English common name is chlorpyrifos, and its chemical molecular formula is C 9 h 11 ClNO 3 PS, other names: Termite Qing, Lanzhu, Lesiben, Killing Insect, Telokay, Taosong. It is an organophosphate broad-spectrum insecticide and acaricide with contact and stomach poisoning effects. Chlorpyrifos is easy to degrade in the environment and is safe for the environment; it has a long duration and is widely used in the control of various crops such as citrus, cotton, corn, apple, pear, rice, peanut, soybean, w...
