At this time, spraying herbicides can effectively eliminate weeds without harming konjac. After konjac germination, you can also use herbicides to weed, but you can only use quizalofop-p-ethyl, you can not use glyphosate herbicides, if the weeds are particularly large, quizalofop-p-ethyl is not used, so when using herbicides, be sure to be timely, be sure to use when the weeds are small.
