Embodiment 1

[0028] Weigh 10% pyrimethan, 10% cyflufen, 4% TERSPERSE 4894 (produced by Huntsman, USA), 1.5% TERSPERSE 2500 (produced by Huntsman, USA), 1% TERSPERSE 2020 (produced by Huntsman, USA) produced by the company), 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Co., Ltd.), deionized water added to 100% parts by weight. The above-mentioned raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 20% pyrimethidin·cyflumetate suspension concentrate.

Embodiment 2

[0030] Weigh 15% pyrimethan, 5% cyflumetate, 3% TERSPERSE 4894, 1% TERSPERSE 2500, 0.3% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer, deionized Water is added to 100% by weight. The above-mentioned raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 20% pyrimethidin·cyflumetate suspension concentrate.

Embodiment 3

[0032] Weigh 20% pyrimidan, 10% cyflumetate, 4% GY-D06, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1% sodium lauryl sulfate, 3% white Carbon black, 3% sodium polyphosphate and kaolin are added up to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 30% pyrimidamide-cyflumet-aben wettable powder.

Abstract

The invention discloses an acaricidal composition containing pyriminostrobin and cyflumetofen. Effective active ingredients of the acaricidal composition consist of pyriminostrobin and cyflumetofen, and the weight ratio of pyriminostrobin to cyflumetofen is (1: 10) to (10: 1). The composition disclosed by the invention can be prepared into agriculturally-acceptable preparation forms, such as suspensions, wettable powder, water-dispersible granules and dispersible oil suspensions. According to the acaricidal composition, the ingredients are reasonable, the insecticidal effect is good, and the activity and insecticidal effect of the acaricidal composition are not achieved through the simple superposition of the activity of each component; compared with the existing single preparation, besides having a remarkable insecticidal effect, the acaricidal composition has a remarkable synergism has good safety to crops and meets the requirements of pesticide preparations for safety; the acaricidal composition has remarkable prevention and treatment effects on Panonychus citri McGregor, Panonychus ulmi and Tetranychus cinnabarinnum Boisduval.

Description

technical field [0001] The invention relates to an acaricidal composition, the effective active ingredients of which are pyrimidan and cyflufenid, belonging to the technical field of compound pesticides. Background technique [0002] Harmful mites in agricultural production are also called spider mites, yellow spiders, etc., and belong to the order Arachnida Acarina. It mainly harms citrus, apple, cotton, vegetables, wheat and other crops. Most of the harmful mites gather on the back of the leaves, and the adults and nymphs use their mouthparts to pierce the leaves and suck the juice. When pest mites occur, it is the most effective means to use acaricides to prevent and control them. At present, the pesticides registered in the Ministry of Agriculture for the prevention and control of agricultural pests mainly include abamectin, pyridaben, propargite, and fenbutatin. It has developed resistance to it, and it is urgent to invent a kind of pesticide that can effectively preve...
