Abstract

The invention discloses a suspended seed coating agent for controlling brassicaceous vegetable phyllotreta striolata fabricius. The suspended seed coating agent can effectively control cabbage phyllotreta striolata fabricius, and meanwhile a cabbage root knot nematode disease can be controlled. The suspended seed coating agent contains pyraclostrobin, fluopyram and thiamethoxam, and the rest are ordinary auxiliary components in preparation processing, wherein the weight ratio of the pyraclostrobin to the fluopyram to the thiamethoxam is (2-10):(2-12):(10-30), and the weight ratio is preferably 2.4:5.6:20. By means of the suspended seed coating agent, the pesticide active component usage amount can be reduced, the control efficiency can be improved, the use cost can be reduced, and pollution to the environment can be reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a suspension seed coating agent for preventing and treating cruciferous vegetable Flea beetle flavus and a preparation method thereof. The active ingredients of the suspension seed coating agent include pyraclostrobin, Fluopyram and Thiamethoxam. Background technique [0002] The flea beetle belongs to the family Coleoptera and is commonly known as dog lice, vegetable lice, fleas, soil fleas, yellow fleas, etc. Flea beetle can harm a variety of plants, especially likes to eat cruciferous plants. It mainly harms cabbage, mustard greens, radishes, cabbage, Chinese kale, rapeseed, cauliflower, etc. in cruciferous vegetables. The flea beetle has a wide distribution and is distributed in more than 50 countries and regions in Asia, Europe, North America, and South Africa. It has become one of the most difficult worldwide pests to control in the production of cruciferous...
