I need to spray a large drainage ditch to kill Johnson Grass and other weeds. I'll be mixing the Oust with 2 ounces of Glyphosate per gallon along with surfactant and dye marker in a 15 gallon tank. How much Oust do I include per gallon for good post and pre-emergent control? I've used the Oust/Glyphosate mixture many times before with great success, but can't remember how much Oust I included.
In the states of Louisiana and Texas, Bayer Oust XP Herbicide may be used for weed control on dry, drainage ditch banks. Do not apply in or on irrigation ditches or canals including their outer banks. It is applied at 1 1/3-2 oz per acre.
