Seed coating agent for preventing and treating peanut root rot and preparation method thereof

The invention relates to the field of seed coating agents, and particularly discloses a seed coating agent for preventing and treating peanut root rot and a preparation method of the seed coating agent. According to the invention, two peanut varieties with high susceptibility to root rot are used as test materials, and fludioxonil, azoxystrobin and thifluzamide are selected as effective components by researching the influence of the effective components of different seed coating agents on the seedling emergence and seedling stage growth of peanuts and the control effect on the root rot; the prepared seed coating agent has a very good prevention and treatment effect on peanut root rot and is beneficial to improvement of the peanut yield; the seed coating agent is prepared through an electrostatic spinning technology, and compared with a traditional seed coating agent, the seed coating agent developed through the method is better in air permeability and water permeability, controllable release of effective comp
