Complete broad-spectrum postemergence herbicide for non-crop, industrial, turf and Maintaining a large gradient such as occurs during good growing conditions improves herbicide absorption. Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 4 hours. Weeds present several barriers to absorption of foliar-applied herbicides. Figure 1. Glyphosate moves with photoassimilate from source (leaf) to sink meristematic regions such as roots (shown) and the shoot (not shown). Effects of water quality and spray volume on glyphosate phytotoxicity. However, many factors, including droplet size and equipment type, determine drift potential at any given wind speed. Might be able to avoid glyphosate altogether. performance. Risks to bees are uncertain for uses with application rates above 5.7 pounds acid equivalent per acre, such as pasture, non-crop sites, and tree crops.
