Goal® 2XL gives you “extra long” control, up to 8 months, on dozens of broadleaf weeds and grasses, making it a proven winner in your residual herbicide program. Goal 2XL works by delivering both contact pre- and post-emergence control. It controls actively growing weeds and also forms a soil barrier to block the establishment of emerging weeds in tree nuts, cotton, grapes, tree fruits and many vegetables for an extended period of time.
