Since 2013, the Company has cooperated with Bayer in customized production of premium seed coating formulation referred to as Gauqiao + Dingmiaoxin + Raxil, which selects green agent to be the coating of corn seed.
Gauqiao (imidacloprid) is at present a worldwide popular seed treatment-purpose super-strong systemic insecticide, which is widely applied in developed countries to production of peanut, cotton and white potato, being very effective against underground pest like grubs and aphids, particularly capable of increasing the emergence of seedling. Dingmiaoxin (metalaxyl+ipconazole) is effective in protection of corn against seedling stem rot caused by fungus.
