Use & Control
// For year-round annual grass control, make one application of 3 oz/A in the late winter and another 3 oz/A in the late summer.
// Apply Rezilon herbicide at 3-5 fl oz/A in late winter (January - February) to control summer annual weeds.
// Apply 3-5 fl oz/A following a late summer (August - September) cutting for winter annual weed control.
// Do not exceed 6 fl oz/A of Rezilon in a 12-month period with sequential applications.
// When Rezilon herbicide is applied at a rate greater than 3 fl oz/A, hay may not be harvested until 40 days after application.
// There are no grazing restrictions following the application of Rezilon herbicide.
// Factors including soil type, rainfall and the amount of vegetation surface debris and the time of treatment may affect weed control.
// If the herbicide is not activated by rainfall prior to germination, control will be reduced.
// Rezilon is a preemergent herbicide that requires an activating rainfall or irrigation (0.25-0.5”) to be effective. Additionally, it will only provide effective control in areas covered by the target rate. Annual weed escapes will occur if coverage is uneven or if a lower effective rate is applied between spray swaths.

Tank mix to target winter weeds
- Pre-emergent herbicides such as Rezilon™ are not meant to control emerged weeds, as the active ingredient is a root inhibitor and works to prevent seedling germination in the top ½” to 1” of the soil. Applications of Rezilon should be made before the target weed begins to germinate in order to prevent in-season weed seed germination.
- Weather does not always cooperate and can create delays in herbicide application plans. When delays occur, target weeds may already be germinating, or even emerged, at the time of herbicide application. In these situations, you can increase your herbicide program success by incorporating tank mix partners to target emerged weeds.
Tank mix partners:
- Roundup® (4 lb) at 8-10 fl oz/A
- Pastora® at 1-1.5 oz/A
- Cimarron® Plus at 0.5 oz/A or higher
- Plateau® (imazapic) at 6-8 fl oz/A –
*The options above may not work if the user has species that are resistant to the particular mode of action. Roundup, Pastora, and Plateau may cause yellowing and stunting to Bermuda
- Paraquat (Gramoxone®) – 1-2 pts/A (this is a restricted-use pesticide)
