Embodiment 2

[0032] Preparation Example 2: 20% cyflumetate tetrafenazine emulsion in water.

[0033] Weigh 5% cyflumetate, 15% tetrafenazine, 3% Nongru 2201#, 1.5% nonylphenol polyoxyethylene ether phosphate, 2% tristyrylphenol polyoxyethylene ether phosphate, 2% Add Span-60#, 1% epichlorohydrin, 5% ethylene glycol, 18% xylene, 0.3% xanthan gum, 0.5% sodium benzoate, and deionized water to 100%. The above raw materials are mixed and emulsified by high-speed shearing to prepare 20% cyflumetofen-tetrafenazine aqueous emulsion.

[0034] This embodiment is used for controlling citrus spider mite. 20% cyflumetate·tetrafenazine aqueous emulsion is diluted 1500 times and sprayed, and the control effect is 92.9% after 7 days of application. 20% cyflumetazine suspension was diluted 1000 times and sprayed, and the control effect was 84.6% 7 days after application; 20% tetrafenazin suspension was sprayed by 1000 times dilution, and the control effect was 59.0% 7 days after application.

Embodiment 3

[0035] Preparation Example 3: 80% cyflumetate tetrafenazine water dispersible granules.

[0036] Weigh 25% cyflumetate, 55% tetrafenazine, 4% TERSPERSE 2700 (produced by Huntsman, USA), 4% diffusing agent NNO, 4% pull-off powder BX, 3% K-12, 5% white Add carbon black, 5% ammonium sulfate, and diatomaceous earth to 100%. The above raw materials are mixed, pulverized by ultra-fine airflow, granulated, dried, and sieved to obtain 80% cyflumetate·tetrafenazine water-dispersible granules.

[0037] This example is used to control cotton spider mites. 80% cyflumetate·tetrafenazine water dispersible granule is diluted 5000 times and sprayed, and the control effect is 100% within 7 days after application. 20% cyflumetazine suspension was diluted 1000 times and sprayed, and the control effect was 79.3% 7 days after application; 20% tetrafenazin suspension was sprayed at 1000 times dilution, and the control effect was 50.9% 7 days after application.

Abstract

The invention relates to a synergistic mite killing composition containing cyflumetofen and clofentezine, wherein the mass ratio of cyflumetofen to clofentezine is 10:1-1:10. The synergistic mite killing composition is suitable for preventing and treating various pest mites in agricultural field; combination of two active ingredients enables obvious synergic effect, thereby the preventing and treating effects can be enhanced, the pesticide application amount is reduced, the cost is reduced and the environmental pollution is reduced. The synergistic mite killing composition is in favor of resistance management of pest mites, and has large economic benefit and social benefit for popularization and application.

Description

technical field [0001] The invention relates to an acaricidal composition, which uses cyflufenofen and tetrafenazine as active ingredients and is used for preventing and controlling agricultural pest mites. Background technique [0002] Acarids, commonly known as red spiders, are pests of the class Arachnida. Most of the common harmful mites belong to the orders Eucarina and Acarina, and they are one of the important pests that damage various crops. Acarids damage the leaves, stems and flowers of plants, etc., and suck the stems and leaves of plants. They are common harmful organisms on fruit trees, cotton, nightshade vegetables and ornamental flowers. In the early stage, there are a large number of pinpoint-sized yellowish-brown dots on the front of the leaves, and in the later stage, the leaves shrink and fall off from the bottom to the top, resulting in a large number of fallen leaves. Sometimes it occurs from the leaves in the middle of the plant, and the leaves gradual...
