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

[0021] Example 1: 30% etoxazole · cyflufenate suspension concentrate.

[0022] Weigh 10% etoxazole, 20% cyflumetate, 8% methylnaphthalenesulfonic acid formaldehyde condensate, 0.8% xanthan gum, 1.5% bentonite, 5% agricultural milk 600#, 5% glycerol, remove Make up to 100% with ionized water. The above raw materials were mixed, dispersed by high-speed shearing for 30 minutes, and then ground with a sander to prepare a 30% etoxazole·cyflumetate suspension concentrate.

Embodiment 2

[0023] Example 2: 25% microemulsion of etoxazole and cyflufenate.

[0024] Weigh 10% etoxazole, 15% cyflumetate, 8% ethyl acetate, 8% diethyl phthalate, mix and dissolve the three fully and enter the blending kettle, then add 2% alkyl Phenol polyoxyethylene ether, 8% polyol fatty acid ester and its ethylene oxide adduct, 4% sodium di-octyl maleate sulfonate, 1.5% antioxidant 264, after fully stirring and dissolving, Make up to 100% with deionized water. Continue to stir until it becomes transparent to prepare a 25% etoxazole-butaflufen microemulsion.

Embodiment 3

[0025] Example 3: 40% etoxazole · cyflufenate emulsion in water.

[0026] Weigh 15% etoxazole, 25% cyflumetate, 2.5% emulsifier T-60, 2% Span-60#, 5% Nongru 600# phosphate, 1% triphenyl phosphite, 8% propylene glycol , 8% cyclohexanone, 10% xylene, 0.3% xanthan gum, 0.5% formaldehyde, deionized water added to 100%. The above raw materials are mixed and emulsified by high-speed shearing to prepare 40% etoxazole-butaflufen water emulsion.

Abstract

The invention discloses a synergistic acaricidal composition containing etoxazole and cyflumetofen. The acaricidal composition includes a first effective component etoxazole, and a second effective component containing cyflumetofen and commonly used auxiliary components, wherein a weight ratio of the etoxazole to the cyflumetofen is 20:1-1:20. The acaricidal composition has obvious synergistic effect after formulation, and control effect on mite on citrus, apple and cotton better than that of individual usage of the two single dosage, and can effectively reduce the usage amount of pesticides, thereby reducing drug cost and environmental pollution, and at the same time overcoming defect of ineffectiveness on mite during individual usage of etoxazole.

Description

technical field [0001] The present invention relates to a pesticide acaricidal composition and its application field, specifically, a binary compound compounded with etoxazole and cyflufenofen as active ingredients, which is used to prevent and control various harmful mites on crops, such as the whole Claw mites, Tetranychus urticae, Tetranychus cinnabarinus, Rust mites, etc. 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 su...
