Embodiment 1

[0026] Weigh 7% pyrimethan, 70% propargite, 4% agricultural milk 500#, 2% agricultural milk 600#, 3% agricultural milk 2201#, 2% epichlorohydrin, and xylene to 100% by weight . The above raw materials are mixed, stirred and dissolved completely to obtain 77% pyrimethan-propargite emulsifiable concentrate.

Embodiment 2

[0028] Weigh 10% pyrimethan, 30% propargid, 5% Nongru 500#, 3% TX-10, 4% Nongru1601#, 5% cyclohexanone, 5% epichlorohydrin, solvent oil S -150 is added to 100% by weight. The above-mentioned raw materials are mixed, stirred and dissolved completely to obtain 40% pyrimethan-propargite emulsifiable concentrate.

Abstract

The invention discloses an acaricidal composition containing pyriminostrobin and propargite. Effective active ingredients of the acaricidal composition consist of pyriminostrobin and propargite, and the weight ratio of pyriminostrobin to propargite is (1: 10) to (5: 1). The composition disclosed by the invention can be prepared into agriculturally-acceptable preparation forms, such as emulsifiable concentrate and microemulsion. 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 preparations, 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 containing pyrimidan and propargid, the active ingredients of which are pyrimidan and propargid, 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 of pesticide ...
