Hexazinone is a triazine herbicide used against many annual, biennial and perennial weeds as well as some woody plants. It is mostly used on non-crop areas; however, it is used selectively for the control of weeds among sugar cane, pineapples, and lucerne. Hexazinone is a systemic herbicide that works by inhibiting photosynthesis in the target plants. Rainfall or irrigation water is needed before it becomes activated.
Registered forestry, rangeland, right-of-way uses: forestry use on Christmas tree plantations, conifer nurseries, conifer release, forest plantings; terrestrial food crop use on pastures, rangeland, and fallowland; terrestrial nonfood crop use on rights of way and industrial and facility sites
Target Plants: Hexazinone is used to control broadleaf weeds, grasses, and woody plants.
Mode of action: Hexazinone inhibits photosynthesis. It is readily absorbed through leaves and roots and moves in an upward direction through the plant.
Method of application: aerial broadcast; basal soil treatment; undiluted spot treatment; tree or brush injection
Timing Of Application: Apply after ground thaws; broadcast application in the spring; best performance when application is followed by rainfall and warmer temperatures; do not apply to saturated soils. In low-moisture areas can be applied in fall before snow fall.
