Embodiment 1
[0035] Weigh 5% pyrimethan, 25% bifenazate, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.3% xanthan gum, 5% propylene glycol , 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29, produced by Nanjing Sixin Applied Chemicals Company), deionized water to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 30% pyrimidamide-bifenazate suspension concentrate.
Embodiment 2
[0037]Weigh 10% pyrimethan, 20% bifenazate, 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 raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 30% pyrimidamide-bifenazate suspension concentrate.
Embodiment 3
[0039] Weigh 30% pyrimidan, 6% bifenazate, 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 36% pyrimidan·bifenazate wettable powder.

Abstract
The invention discloses an acaricidal composition containing pyriminostrobin and bifenazate as well as application of the acaricidal composition. The acaricidal composition consists of effective ingredients including first active ingredients of pyriminostrobin and second active ingredients of bifenazate, and the weight ratio of the first active ingredients to the second active ingredients is 1:10-5:1. The composition can be prepared into agriculturally allowed suspending agents, wettable powder, water dispersible granules or dispersible oil suspension agent dosage forms. The acaricidal composition has the advantages that the ingredients are reasonable, the insect killing effect is good, in addition, the activity and the insect killing effect are not the simple superposition of the activities of each ingredient, compared with the existing simple preparation, the acaricidal composition has the obvious insect killing effect and has the obvious synergistic effect, good safety is realized on crops, the safety requirement of pesticide preparations is met, and the acaricidal composition has the obvious preventing and curing effects on panonychus citri mcgregor, European red mite and cotton spider mites.
Description
technical field [0001] The invention relates to an insecticidal composition, which is composed of a first active ingredient, pyrimethanil, and a second active ingredient, bifenazate, and belongs 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 o...
