Envu Environmental Science Rejuvra Herbicide, 2.5 Gallon

Rejuvra is a restoration herbicide that features a unique mode of action for rangeland providing long-lasting control of invasive annual grass and broadleaf weed species including cheatgrass, medusahead, ventenata and red brome. Managing the soil seed bank of these invasive annual plants is now a reality.

With the help of Rejuvra (indaziflam) herbicide, it is possible to stop invasive annual grasses by preventing germination of their seeds and depleting the weed seed bank. This pre-emergent restoration tool is showing consistent control for up to four years with just one application.

Key Benefits

• Consistent, long-term weed control: Up to four seasons of control of invasive grasses, depending on weather, grazing pressure, and other factors.
• Non-volatile and good photo stability: Does not leave the application site as a vapor and has good stability when exposed to sunlight. This allows flexibility in application timing relative to rainfall events needed to activate the herbicide.
• Releases perennial native vegetation: Perennial plants respond quickly to the additional water and nutrients that become available when invasive annual grasses are controlled.
• Resistance management: An effective tool for managing herbicide-resistant weeds.
• Reduced time and labor costs: Fewer applications are needed to control weeds.
• Flexible tankmixing: Can be tankmixed with both pre- and post-emergent herbicides.
• No grazing restrictions: For an application rate of 5 oz/acre.

Use & Control

• Uniform soil coverage is important
• Apply 5 oz/acre of Rejuvra herbicide at a minimum of 5 gallons per acre by air; for ground application, use spray volumes of 20-30 GPA total spray mix (apply up to 7 oz/acre on areas that are not grazed by livestock)
• For good first-year control, Rejuvra must be applied prior to germination of the target weeds
• To control weeds that have already germinated, a tank mix partner that provides post-emergence control is needed
• Rejuvra is a pre-emergent herbicide and will only provide effective control in areas covered by the target rate. Annual grass escapes will occur if coverage is uneven or if a lower effective rate is applied between spray swaths.
