Producing high-quality hay is a year-round endeavor, and Envu is here to help producers maintain hay yield this upcoming season. For years, producers have relied on Bayer Range & Pasture products and expertise to solve their toughest problems. This will continue as Envu tightens its focus on environmental science, including range and pasture spaces.

It is important to stay on top of weeds before the growing season and long after the baler is parked. A winter application of Rezilon® herbicide from Envu is the most effective strategy for managing warm-season annual weed species and maintaining high-quality, high-production perennial hay fields.

Controlling weeds before emergence is a more effective management strategy than spraying after germination. This is because Rezilon is an easy-to-use preemergence herbicide that’s effective in controlling warm- and cool-season annual weed species in hayfields and other hay production sites.

Rezilon is not meant to control emerged weeds because the active ingredient is a root inhibitor and works to prevent seedling emergence in the top of the soil. Applications of Rezilon should be made well before the target weed begins to germinate in order to prevent in-season weeds from emerging. By targeting broadleaf and annual grass weeds early in established hayfields, Rezilon promotes increased fertilizer and water utilization by desirable forage for higher-quality hay.

With a long residual, Rezilon offers a flexible application window. The herbicide can sit on the surface for weeks, with no degradation from sunlight, while waiting on rainfall for activation. The active ingredient in Rezilon, indaziflam, is a root inhibitor and works to prevent seedling establishment in the top 0.5 to 1 inch of the soil. Overall, the herbicide controls more than 60 summer and winter broadleaf and annual grass weeds, including species that have demonstrated herbicide resistance such as ryegrass. Other particularly challenging weeds controlled by Rezilon herbicide are sandbur, crabgrass, goosegrass and annual foxtail.

When targeting warm-season annual weeds, such as crabgrass, the optimal application period for Rezilon is in the winter before weeds begin to germinate. This is a dormant time of the year, and Envu experts advise producers that fields treated with Rezilon should receive rainfall to activate the herbicide before germination occurs in the new season. There are no grazing restrictions following Rezilon applications.

When applied according to label directions, growers could see better hay quality thanks to effective control that leads to higher-quality forage on your first cut, which benefits your bottom line and your reputation.

Hay producers looking to stop weeds should consider an application of Rezilon herbicide. Now is the perfect time to get ahead of warm-season weeds to support high-quality hay production next season. Visit to learn more about Rezilon herbicide or see your local Envu product dealer.

Rezilon herbicide provides 4-6 months of anticipated control per application.
