Picolinafen active herbicide is a selective, post-emergence herbicide for use on winter cereals, such as wheat, barley, oats, rye and triticale for control of meadow grasses and annual broad-leaved weeds, including poppies, field pansies, cleavers, wild radish and hedge mustard. Picolinafen acts by disrupting photosynthesis, making the weeds look “bleached” as it begins to work. It is available as PicoPro® herbicide.
