萎锈灵 - Uses and synthesis methods
| use | This product is a selective systemic fungicide. It uses methods such as seed dressing, stuffy seed and seed soaking to prevent wheat, oats, corn, sorghum, millet and other cereal smut. It can also be used for foliar spraying wine to prevent wheat, beans, pears and other rust diseases, cotton seedling diseases, verticillium wilt, blight, and wood preservatives. This product is effective for Rhizoctonia, especially suitable for seed treatment of cotton, peanuts, vegetables and sugar beets. It has a growth stimulating effect on crops. Wilmus is low-toxic to humans and animals, but it should not be in contact with eyes. Seeds treated with withering rust spirit are not edible or forage. |
| use | Butene amide fungicides have high systemic activity against basidiomycetes and are mainly used to control crop rust and smut |
| production method | α-chloroacetanilide is obtained by the reaction of acetanilide and sulfuryl chloride, and then condensed with mercaptoethanol. Raw material consumption quota: acetanilide 1090kg/t, sulfuryl chloride 880kg/t, mercaptoethanol (>95%)490kg/t, p-toluenesulfonic acid 30kg/t. |
