溴苯腈是选择性茎叶处理触杀型除草剂,主要通过叶片吸收,抑制敏感植物光合作用的各个过程使植物组织迅速坏死。主要用于小麦、大麦、黑麦、玉米、高粱、亚麻等作物田防除蓼、藜、苋、麦瓶草、龙葵、苍耳、猪毛菜、麦家公、田旋花等阔叶杂草。为了解溴苯腈对麦套大蒜田杂草的防效和使用技术,笔者在江苏沿海地区农科所新洋试验站进行了药效试验。 Bromoxynil is a selective shoot-and-shoot herbicide, which is rapidly absorbed by plants and inhibits the photosynthesis of sensitive plants, causing rapid necrosis of plant tissues. Mainly used in crops such as wheat, barley, rye, maize, sorghum, flax and the like for controlling broadleaf miscellaneous leaves such as Polygonum, quinoa, amaranth, grass. In order to understand the effect of bromoxynil on wheat weed control and the use of technology, the author conducted a pharmacodynamic test at Xin Yang Experimental Station of Agricultural Science Institute of Jiangsu Coastal Area.
