Problems solved by technology
Furthermore, the spring sowing temperature in Northeast China has a large temperature difference between day and night, and some varieties often fail to germinate or emerge deformed after being coated with azole alcohol-based seed coating agents.

The invention relates to a novel seed coating for preventing and treating corn soil insect and resisting chilling injury in a seedling stage. The novel seed coating is characterized in that the prescription comprises the following raw materials by weight percent: 3-5% benfuracarb, 8% thiram, 0.6% tebuconazole and 0.01-0.05% of brassinolide. According to the effect of preventing and treating corn stem dwarf seedlings and the phenomena of no emerge seedlings or deformed seedlings caused by chilling injury in the seedling stage of corn, a certain dose of benfuracarb and brassinolide are added into the seed coating, so as to lower the incidence rate of corn stem dwarf seedlings, increase the emergence rate of corn seeds which cannot resist low temperature and tebuconazole hazard, and ensure the safety of agricultural production.
Description
technical field [0001] The invention relates to a novel seed coating agent for preventing and controlling underground pests of corn and resisting chilling damage at seedling stage, which belongs to a seed coating agent for preventing pests of corn. Background technique [0002] The dwarf seedlings of maize stem base cracking in Northeast China (early called cluster seedlings, old man seedlings or Clivia seedlings) were first paid attention to in 1992. At that time, there was a large outbreak in Northeast China. At that time, Sidan 48, Jidan 159, Simi 21, etc. were mainly promoted. Varieties have the most serious occurrence, the general incidence rate is 7%-20%, and the severe plot can reach about 30%. The occurrence rate is close to the loss rate, which poses a serious threat to the sandy soil belt in Northeast China, especially the corn production in Jilin Province. In the following years, the Jilin Provincial Academy of Agricultural Sciences was the first to discover that...
