| Uses | is a systemic conductive post-emergence selective Herbicide and inhibitor of branched chain amino acids that inhibits the biosynthesis of valine, leucine and isoleucine, blocks cell division, and stops the growth of sensitive crops. Mainly used to control broad-leaved weeds of cereal crops wheat, barley, oats, and corn fields, such as amaranth, purslane, wormwood, leeks, pigweed, pigweed, Veronica, cattle Etc., etc., are not effective for stabbing vegetables, field bindweed and valerian. From the leaf stage of wheat and barley to pre-cropping stage, the weeds are released until the 2 to 4 leaf stage, with 75% dry suspension 0.25-0.41g/100m2, 4.5kg water, and 0.2% non-ionic surfactant added. , stem and leaf spray treatment. |
