With the help of Rejuvra™ 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 over multiple years with just one application, making it a long-term, economical solution for the control of invasive annual grasses.
Key Benefits
// Consistent, long-term weed control: Up to four year 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 desirable perennial 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 tank-mixing: Can be tank-mixed with both pre- and post-emergent herbicides.
// Standard PPE requirement: Long-sleeved shirt, long pants, shoes plus socks and chemical-resistant gloves. Follow state requirements if more stringent.
// No grazing restrictions: For applications of 5 oz per acre.
Economic Advantages
By controlling invasive annual grasses, remnant desirable perennial grasses and forbs can recolonize. Forage quantity and quality is improved, and wildfire risk is reduced. Trial work across the western United States showed that areas treated with Rejuvra demonstrated a two-to-three-fold increase in perennial grass biomass, compared to untreated areas. A single pre-emergent application of Rejuvra provides consistent control for multiple years, reducing costs associated with time and labor.
Use & Control
// Uniform soil coverage is important.
// Apply 5 oz/A of Rejuvra herbicide at a minimum of 5 gallons per acre by air; for ground application, use spray volumes of 20-30 gallons per acre total spray mix (apply up to 7 oz/A on areas that are not grazed by livestock).
// For good first year control, Rejuvra must be applied prior to germination of target weeds.
// To control weeds that have already germinated, a tank mix partner 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.
Key Species Controlled
// Cheatgrass or downy brome
// Japanese brome
