虎威是英国卜内门化学公司开发的新型高效选择性除草剂,专用于大豆田防除阔叶杂草。虎威的活性成份为除豆莠(fomesafen),施用到植物上后,可很快被叶部吸收,破坏植物的光合作用,导致叶片组织失绿,引起叶部枯斑,迅速干枯死亡。虎威只摧毁阔叶杂草,在有效用量下,不影响大豆生长,是目前用以防除大豆苗后阔叶杂草的优良的选择性除草剂。一、虎威的物理化学性状:化学名称:5—(2—氯—4—(三氟甲基)苯氧基)—N—
Tigerway is the United Kingdom Bu Neimen chemical company developed a new highly selective herbicide, dedicated to the control of broad-leaved weeds in the soybean field. The active ingredients of Tigerway are fomesafen, which can be quickly absorbed by the leaves after they are applied to the plants, destroying the photosynthesis of the plants, causing the leaf tissues to lose their green color and causing dead spots in the leaves and rapid death from dryness. Huwei destroy only broad-leaved weeds, in the effective amount, does not affect the growth of soybean, is currently used to control soybean seedling broad-leaved weeds excellent selective herbicide. First, the physical and chemical properties of Tigerwell: Chemical Name: 5- (2-chloro-4- (trifluoromethyl) phenoxy) -N-
