Problems solved by technology

[0008] Most of the existing foreign crop seed coating agents are single doses, and the control objects are single. The quality of domestic products is uneven. At the same time, there are not many products for insect and disease prevention. The aging phenomenon of chemical ingredients exists, and new seed coating ingredients are urgently needed.

Abstract

The invention discloses a seed coating agent which comprises active components. Active components comprise sterilizing agents and insecticides, the sterilizing agents comprise thifluzamide and tebuconazole, the insecticides comprise clothianidin, the weight ratio of the sterilizing agents to the insecticides is 20:1-1:20, and the rest water. According to the seed coating agent configured by the components, seeds are coated according to the ratio of pesticides to seeds which is 1:2-1:400, the seed coating agent has good preventing effect on earlier stage diseases and insect pests of corns, and indexes such as emergence rate, plant height fresh weight are remarkably improved and obviously better than those of a commonly used coating agent. The seed coating agent is used for corns, low in cost and convenient to prepare and can be applied to coating of crop seeds and tubers such as soybean, wheat, potatoes and rice, and original chemicals of the coating agent are easily obtained.

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...
