Abstract: This study reported the field experimental results of 15% arbofuran-Carbendazim- Thiram for Seed Coating Treatment (CCT SC) in 8 trial plot with different ecological condition in Yunnan province. The results showed that CCT SC provided integrated control of seed-borne and soil-borne disease, seedling insect, and good seedling growing. Coating treatment with this chemical increased seed germination and seedling emergence, fresh weight of 100 plants, amount of stem and leave of seedling, and field yield at significance level. This seed coating chemical is specific for developing and extension in Yunnan province. The chemical / seed ratio is 1:40, and should change a little in different ecological environment.
