Abstract

The invention discloses an efficient, broad-spectrum and environment-friendly maize seed coating agent. The compositions in percentage by weight of raw materials used to prepare the maize seed coating agent are: 3 to 8 percent of chlopyrifos, 0.5 to 5 percent of tebuconazole, 5 to 10 percent of trametan, 1 to 2 percent of film former, 2 to 5 percent of an emulsifying agent, 2 to 5 percent of dispersing agent, 0.1 to 1 percent of antifoam agent, 4 to 5 percent of antifreezing agent, 0.5 to 1.5 percent of warning coloration and the balance being water, wherein pesticide is chlopyrifos; and bactericide consists of tebuconazole and trametan. The product of the maize seed coating agent can be used in maize seed; moreover, the seed coating agent product has the advantages of high efficiency, low toxity, environment protection and convenient use, etc., and can effectively control cornfield soil insects such as white grub, wireworm, cutworm and darkling beetle and so on as well as maize diseases such as maize head smut, common smut and caudex rot disease and so on.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and mainly relates to a high-efficiency, broad-spectrum and environment-friendly corn seed coating agent. Background technique [0002] With the widespread application of advanced agricultural technologies such as straw returning technology, conservation tillage technology, and mulching technology in agricultural production, new changes have appeared in the occurrence of diseases and insect pests on crops. Ground pests such as grubs, dayworms, cutworms, and scutellaria, and diseases such as corn head smut, tumor smut, stem rot, and bacterial wilt are becoming more and more serious, resulting in a serious reduction in corn production, which has become a current constraint on corn. One of the main factors of high yield. At present, the prevention and control of the above-mentioned diseases and insect pests mainly adopts chemical seed dressing, seed coating agent coating, underground appli...
