Bifen IT is not a product that is approved for use on edible plants, so if you are using it in equipment that is used for this purpose, be sure the equipment is thoroughly cleaned both before and after applications. It is generally best to use dedicated equipment for use around edibles, and to use separate equipment for herbicides so that there is no residual that may interfere with other applications.
