Example Embodiment

[0019] Example 1: 25% Etoconazole·Terfenpyril Suspension Concentrate.

[0020] Weigh 5% etoxazole, 20% carbofuran, 2.5% tristyrylphenol polyoxyethylene polyoxypropylene ether, 2.5% calcium dodecyl benzene sulfonate, 2% alkylphenol polyoxyethylene ether formaldehyde Condensate sulfate, 0.2% ethylene glycol, 0.1% xanthan gum, 0.4% silicone, 4% glycerol, 0.1% gum arabic, deionized water to make up to 100%. The above-mentioned raw materials were mixed, high-speed shearing and dispersing for 30 minutes, and then ground with a sander to obtain 25% etoxazole·teprofen suspending agent.

Example Embodiment

[0021] Example 2: 30% Etoxazole·Terfenpyril microemulsion.

[0022] Weigh out 10% etoxazole, 20% carbofuran, 10% ethyl acetate, 8% diethyl phthalate, the three are thoroughly mixed and dissolved, and then enter the mixing kettle, and then add 2% alkylphenol to the mixing kettle Polyoxyethylene ether, 8% polyol fatty acid esters and their ethylene oxide adducts, 4% sodium di-secondary octyl maleate sulfonate, 2% antioxidant 264, stir and dissolve thoroughly, then remove Ionized water makes up to 100%. Continue to stir until it becomes transparent, and a 30% etoxazole·Termanil microemulsion is prepared.

Example Embodiment

[0023] Example 3: 40% Etoxazole·Termanil water emulsion.

[0024] Weigh 15% etoxazole, 25% carbofuran, 3% emulsifier T-60, 2% Span-60#, 5% Nongru 600# phosphate, 1% triphenyl phosphite, 8% propylene glycol, Add 8% cyclohexanone, 10% xylene, 0.5% xanthan gum, 0.5% formaldehyde, and deionized water to 100% by weight. The above-mentioned raw materials are mixed, and high-speed shearing emulsification is used to prepare a 40% etoxazole·Termanil water emulsion.

Abstract

The invention discloses an acaricidal composition formed by blending etoxazole and chlorfenapyr. The acaricidal composition comprises the etoxazole serving as a first active ingredient, the chlorfenapyr serving as a second active ingredient, and common auxiliary components, wherein the weight ratio of the etoxazole to the chlorfenapyr in the composition is (20:1)-(1:30), and the weight sum of the etoxazole and the chlorfenapyr counts 1 to 80 percent of the weight of the acaricidal composition. The compound acaricidal composition has an obvious synergistic effect, has better prevention and control effect on oranges, apples and cotton mites than the two single agents which are separately used, and can effectively reduce the consumption of pesticide so as to reduce the pesticide cost and reduce the environmental pollution.

Description

technical field [0001] The invention relates to a pesticide mite-killing composition and its application field, in particular to a binary compound compounded with etoxazole and chlorfenapyr as active ingredients, which is used to prevent and control harmful mites on citrus, apple and cotton. Background technique [0002] Etoxazole, English common name: etoxazole, is a brand-new acaricide with a special structure, and its mode of action is to inhibit the embryogenesis of mite eggs and the molting process from larvae to adults. It is effective for eggs and nymphs, but not for adult mites. Therefore, the best control time is the early stage of pest mite damage. The agent has strong rain resistance, a lasting period of up to 50 days, and is environmentally safe. It has a good control effect on Tetranychus, Tetranychus, Panonychus, Tetranychus urticae, and Tetranychus cinnabarinus on crops such as citrus, cotton, apples, flowers, and vegetables. As a new type of insecticide, e...
