The box of Hyvar X contains one 4-lb. bag.
Hyvar X is primarily a non-selective brush killer and should not be used around residential areas or desirable plants such as jasmine. You can use a grass killer such as Bonide Grass Beater Over the Top Grass Killer Concentrate to control cyonodon dactylon/bermudagrass/wiregrass and other listed grassy weeds in Asiatic jasmine and around many other groundcovers and ornamental plants.
Hyvar X is primarily a non-selective brush killer and should not be used around desirable plants such as sisal. You would have to keep applications outside of the dripline of the trees/plants.
Hyvar X is labeled to treat sandbur (sandspur). Please take a moment to review the product label before making your application for further information.
Hyvar X is not labeled for killing trees. If you want to selectively kill a tree, you would want to drill holes into the stump or use the cut stump method. This means you cut the stump to expose fresh pulp and immediately treat. You may want to try a brush and stump killer product like Fertilome Brush and Stump Killer instead.
