Rezilon is a pre-emergent herbicide formulated to control a broad spectrum of annual grass and broadleaf weeds in established warm-season grasses such as Bermudagrass and Bahiagrass. Manufactured by Envu, Rezilon contains the active ingredient indaziflam, a member of the Group 29 herbicide class. This herbicide is designed to provide long-lasting residual control, making it a valuable tool for land managers and agricultural professionals seeking to maintain weed-free pastures and hayfields.
What Is Rezilon Herbicide?
Rezilon is a selective, pre-emergence herbicide that targets weeds before they emerge from the soil. Its active ingredient, indaziflam, inhibits cellulose biosynthesis in plants, effectively preventing weed seedling establishment. Unlike post-emergence herbicides that require weeds to be actively growing, Rezilon works by creating a barrier in the soil that stops weed seeds from germinating and establishing roots.
Key Features of Rezilon
- Broad-spectrum controlEffective against over 60 weed species, including ryegrass, goosegrass, sandbur, crabgrass, and annual foxtails.
- Long-lasting residual activityProvides extended weed control, reducing the need for frequent applications.
- Selective applicationSafe for use on established Bermudagrass and Bahiagrass pastures and hayfields.
- Flexible timingCan be applied in late summer or late winter to control summer and winter annual weeds, respectively.
Application Guidelines
To achieve optimal results with Rezilon, proper application timing and technique are crucial. The herbicide should be applied to dry soil before weed seeds have germinated. For summer annual weed control, applications are typically made in late winter, while for winter annuals, late summer applications are recommended. The application rate is generally 3 to 5 fluid ounces per acre, depending on the specific weed species and environmental conditions.
It’s important to note that Rezilon is a pre-emergent herbicide and will not control existing weeds. Therefore, fields should be free of actively growing weeds at the time of application. Additionally, the recommended seeding interval after applying Rezilon is 18 months, as the residual activity may inhibit the germination of newly planted seeds during this period.
Safety and Environmental Considerations
While Rezilon is effective in controlling weeds, it is essential to handle and apply the herbicide with care to minimize environmental impact and ensure safety. Users should adhere to all safety instructions provided on the product label, including wearing appropriate protective equipment and avoiding application near water sources to prevent contamination. Proper storage is also important; Rezilon should be kept in a cool, dry place away from direct sunlight and out of reach of children and pets.
Grazing Restrictions
According to the manufacturer’s product label, there are no grazing restrictions following the application of Rezilon Pre Emergent Herbicide. However, it is recommended to keep animals out of the treated area until the product has dried, typically for at least 24 hours, to ensure safety. Always refer to the specific product label for detailed instructions and safety precautions.
