Problems solved by technology

There are many generations of harmful mites and strong reproductive ability. Under suitable temperature and humidity conditions, the number of harmful mites doubles rapidly in a short period of time, so it is easy to develop resistance to acaricides, and the control effect decreases. serious damage to crops

Embodiment 1

[0019] Example 1: 25% etoxazole · chlorfenapyr suspension concentrate.

[0020] Weigh 5% etoxazole, 20% chlorfenapyr, 2.5% tristyrylphenol polyoxyethylene polyoxypropylene ether, 2.5% calcium dodecylbenzenesulfonate, 2% alkylphenol polyoxyethylene ether formaldehyde Condensate sulfate, 0.2% ethylene glycol, 0.1% xanthan gum, 0.4% silicone, 4% glycerin, 0.1% gum arabic, deionized water to make up to 100%. The above raw materials were mixed, dispersed by high-speed shearing for 30 minutes, and ground with a sander to prepare a 25% etoxazole·chlorfenapyr suspension concentrate.

Embodiment 2

[0021] Example 2: 30% etoxazole · chlorfenapyr microemulsion.

[0022] Weigh 10% etoxazole, 20% chlorfenapyr, 10% ethyl acetate, 8% diethyl phthalate, mix and dissolve the three fully and enter the blending kettle, then add 2% alkylphenol to the blending kettle Polyoxyethylene ether, 8% polyol fatty acid ester and its ethylene oxide adduct, 4% sodium di-sec-octyl sulfonate maleate, 2% antioxidant 264, after fully stirring and dissolving, remove Make up to 100% with ionized water. Continue to stir until transparent to prepare 30% etoxazole·chlorfenapyr microemulsion.

Embodiment 3

[0023] Example 3: 40% etoxazole · chlorfenapyr emulsion in water.

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

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...
