Prothioconazole (prothioconazole) belongs to a novel broad-spectrum triazolethione bactericide, has good systemic activity, excellent protection, treatment and eradication activity and long lasting period; through a large number of field efficacy tests, the results show that the prothioconazole has good safety, good effects of preventing and treating diseases and obvious yield increase, is mainly used for preventing and treating a plurality of diseases of cereal crops such as wheat, barley, rape, peanut, rice, bean crops and the like, and has good effects of preventing and treating almost all wheat diseases.

Thiamethoxam is an insecticide in neonicotinoids, can selectively inhibit nicotinic acetylcholine esterase receptors of central nervous systems of insects, further blocks normal conduction of the central nervous systems of the insects, and causes death of pests when paralysis occurs. The thiamethoxam has the characteristics of contact poisoning, stomach toxicity, systemic activity, higher activity, better safety, wider insecticidal spectrum, high action speed, long lasting period and the like.

Tetrachlorantraniliprole and o-formylaminobenzamide pesticides mainly activate ryanodine receptors, release calcium ions stored in smooth muscle cells and striated muscle cells, cause muscle conditioning weakness and paralysis until pests die finally.

The seed coating agent is a pesticide preparation with film forming property for treating plant seeds. The seed coating agent is composed of active ingredients and auxiliary agents, and can be coated on the surface of seeds directly or after being diluted to form a protective film agent with certain strength and permeability. The seed is treated by the seed coating agent, so that the effects of protecting and strengthening the seedling, improving the stress resistance and comprehensively preventing and treating the diseases and insect pests in the seedling stage are achieved, the purposes of yield preservation and yield increase are further achieved, meanwhile, the seed coating agent is used in a concealed mode, targets are clear, centralized treatment is achieved, the environment and ecological protection is facilitated, the medicine, the time and the money are saved, the resources are saved, the cost is reduced, and the economic and ecological benefits are remarkable.

In view of the advantages, the broad-spectrum bactericidal property of the prothioconazole and the efficient and safe insecticidal property of the thiamethoxam and the tetrachlorantraniliprole are utilized, and the prothioconazole, the thiamethoxam and the tetrachlorantraniliprole are used as effective components of the seed coating agent, so that the effects of preventing insects and diseases of crops in the seedling stage are achieved, the pesticide, the time and the money are saved, the resources are saved, the cost is reduced, and the environment and the ecology are protected. And no report on the compound seed coating agent of prothioconazole, thiamethoxam and tetrachlorantraniliprole is found so far.

When the dry powder seed coating agent is used, the dry powder seed coating agent needs to be diluted by water and coated according to a proportion. The dry powder seed coating has the problem that the formed coating is easy to fall off. Therefore, there is a need for a seed coating agent containing prothioconazole, thiamethoxam and tetrachlorantraniliprole with good coating performance.
