| use | this product belongs to fluorodiphenyl ether, which is an ultra-low dosage of selective herbicide before bud and after bud. weeds are mainly killed by absorbing chemicals through coleoptile and mesocotyl. Suitable for rice, soybean, wheat, cotton, corn, oil palm, vegetables and orchards, etc., to control broad-leaved weeds and some gramineous weeds, such as Commelina communis, barnyard grass, Cyperus, Sesbania, brome, Datura, etc., the dosage is 1~2g active ingredient/100 m2. For example, 4~6 days after rice transplanting, barnyard grass bud stage to 1.5 leaf stage, with 24% emulsifiable concentrate 1.5~2.3mL/100 m2, made of toxic soil evenly spread. 0 is also available. 5% granules. It is used to apply pesticide to soybean, cotton and other crops before seedling after sowing, and spray soil surface evenly with 24% emulsifiable concentrate 7.5mL/100 m2. A certain degree of phytotoxicity may occur during the use of ethoxyfluoroether, which can generally be recovered after half a month. Used as a herbicide. Before and after buds, apply to control monocotyleaved and broadleaf weeds in coffee, conifers, cotton, citrus and other fields. Can be made into emulsifiable concentrate for use. used in rice, soybean, corn, cotton, vegetables, grapes, fruit trees and other crop fields to control annual broad-leaved weeds and grass, Cyperaceae weeds low toxicity, contact type herbicide. exerts its herbicidal activity in the presence of light. The application effect is the best before and after the bud. It can kill broad-leaved weeds, sedge and barnyard, but has inhibitory effect on perennial weeds. Control objects: monocotylea and broadleaf weeds in transplanted rice, soybean, corn, cotton, peanuts, sugarcane, vineyards, orchards, vegetable fields and forest nurseries can be controlled. |
| production method | preparation method -3, 4-dichlorotoluene and resorcinol are used as raw materials through chlorination, fluorination, etherification, nitrification, alcoholysis and other reactions. Preparation method 2: 3, 4-dichlorotrifluorotoluene and resorcinol salt are used as raw materials, reacted at 140~160 ℃ in a ratio of 1:4, then acylated with acetic anhydride, nitrated with mixed acid at 20~30 ℃, saponified in the presence of inorganic acid, and finally reacted with equimolar bromoethane to prepare ethoxyfluoroether. This method is more reasonable than the preparation method. |
