Abstract

The invention discloses a seed coating agent, which contains the bactericides fludioxonil and difenoconazole and the insecticide dinotefuran as the active components. Specifically, the bactericides fludioxonil and difenoconazole and the insecticide dinotefuran are in a mass ratio of 201:1-1:20, and the balance water. The seed coating agent prepared from the components is subjected to coating according to a drug-seed ratio of 1:2-1:1000, can achieve a very good control effect on earlier stage diseases and pests of wheat, obviously improves the seedling emergence rate, plant height, fresh weightand other indexes, is significantly better than conventional coating agents, is a good coating agent for wheat seeds, and also can be applied to coating of soybeans, corn, potatoes, rice and other crops' seeds and tubers. The coating agent has the characteristics of easily available raw materials, low cost and easy preparation.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a seed coating agent for preventing insects, preventing diseases and promoting growth. Background technique [0002] With the popularity of crop straw returning to the field, the occurrence of plant diseases and insect pests in the early stage of crop growth is becoming more and more common. The seed coating agent is to coat the seeds with a "coat" containing chemicals and other substances, and this layer of coat becomes the seed coating agent. The seed coating agent can effectively prevent and control pests and diseases at the seedling stage of crops, significantly promote the growth of seedlings, effectively reduce the amount of chemicals used, and reduce the degree of environmental pollution from pesticides. [0003] Seed coating agents have been used in agricultural production for many years, with a wide range of applications and high cost performance. It has the functions of preventi...
