Current Herbicide Limitations Currently can use only 4 herbicides to control listed noxious weeds Currently can use only 4 herbicides to control listed noxious weeds Glyphosate is a non-selective herbicide, and 2,4-D, dicamba, and picloram are systemic broad-leaved herbicides Glyphosate is a non-selective herbicide, and 2,4-D, dicamba, and picloram are systemic broad-leaved herbicides These 4 herbicides are not always the most effective or environmentally safe -- picloram (Tordon) cannot be used in areas with permeable soil or a high water table These 4 herbicides are not always the most effective or environmentally safe -- picloram (Tordon) cannot be used in areas with permeable soil or a high water table Currently on cooperative projects, the cooperator must switch chemicals when moving from private land to BLM land Currently on cooperative projects, the cooperator must switch chemicals when moving from private land to BLM land Crossbow (a triclopyr/2,4-D formulation) is typically used on non-BLM lands to control broom species, but cannot be used on BLM Crossbow (a triclopyr/2,4-D formulation) is typically used on non-BLM lands to control broom species, but cannot be used on BLM Few options for safely and effectively treating aquatic weeds Few options for safely and effectively treating aquatic weeds

22. How Vegetation Treatment EIS Would Help More options for effectively treating aquatic noxious weeds More options for effectively treating aquatic noxious weeds Weeds such as purple loosestrife and Japanese knotweed are increasing on the District Weeds such as purple loosestrife and Japanese knotweed are increasing on the District Mechanical methods only prevent seed set and do not kill the plants Mechanical methods only prevent seed set and do not kill the plants Stem injection of aquatic formulations of glyphosate (currently available) to control knotweed can easily exceed the maximum use rates allowed per acre Stem injection of aquatic formulations of glyphosate (currently available) to control knotweed can easily exceed the maximum use rates allowed per acre
