Nonselective, postemergence weed control for use in field and container nurseries, landscape beds, walkways, patios, beneath greenhouse benches, along driveways, and other non-crop areas. Rapid burn-down of weeds with no soil residual. Cool weather does not reduce the efficacy of Reward as dramatically as other postemergence herbicides. For this reason, Reward is often used in the winter and early spring to control winter annual weeds.
|Amount of Active Ingredient||Amount by Formulation|
|Per Acre||0.25 to 1||0.5 to 2 qt|
|Per 100 gal||0.5 to 1.0 lb||1 to 2 qt|
|Per 1 gal||0.166 fl oz||4 teaspoons|
Provides only "top-kill" of perennial weeds and most established annual weeds. Has no soil residual and thus does not affect weeds that emerge after application. Addition of a systemic herbicide in a tank-mix with Reward may be needed for control of established perennial weeds.
A 75 percent nonionic surfactant should be added to the spray solution. Apply for full coverage and thorough weed contact in a minimum of 15 gallons of spray per acre. Higher spray volumes have provided more consistent weed control in North Carolina tests. Best control is achieved if weeds are young when treated. Re-treatment may be necessary for grasses and established weeds.
Nonvolatile. Strongly adsorbed by clay particles in the soil; little leaching expected.
Interacts with light to produce superoxides that destroy plant cells. On a sunny day, treated tissues will appear water-soaked within hours. Necrosis follows within one or two days. Dead tissue usually turns black. WSSA Group 22; HRAC Group D. https://content.ces.ncsu.edu/photosystem-i-bipyridillium-herbicides
