The Vegetation Management business within Bayer CropScience LP, announces the label for Rezilon™ Herbicide has received approval from the U.S. Environmental Protection Agency (EPA). The herbicide is federally registered for the control of summer and winter annual broadleaf weeds and grasses in pastures and hayfields, non-irrigation ditchbanks, fire breaks and any sites managed for hay.

Rezilon herbicide is a pre-emergence herbicide that provides consistent control of annual grass and broadleaf weeds in warm-season bermudagrass and bahiagrass hay fields. It also helps protect desirable warm-season grasses while managing unwanted annual grasses in the same site, a quality that few herbicides can maintain.

For year-round control of broadleaf and annual grass weeds, Rezilon is applied in both late summer and late winter. Applications made in August, September or October will provide pre-emergence control of fall-emerging weeds, while applications made in January or February will provide pre-emergence control of spring-emerging weeds.

Rezilon herbicide includes indaziflam, an innovative active ingredient that works primarily to target broadleaf and annual grass weeds in established bermudagrass. With indaziflam, Rezilon gives growers the opportunity to use a new mode of action to achieve the effective weed control they desire on their hay production sites. By eliminating weeds, Rezilon also helps to increase fertilizer and water utilization in hay and forage production. In fact, when applied according to label directions, growers could see a higher-quality forage produced on their first harvest.

“We are pleased to see Rezilon herbicide receive federal approval from the EPA,” said Bayer Head of Vegetation Management Marketing, North America, Tiffany Fremder. “Rezilon will give hay growers the weed control they’ve been asking for, while also allowing them to improve quality on their hay production sites.”

Overall, the herbicide controls more than 60 broadleaf and annual grass weeds, including species that have developed herbicide resistance, such as ryegrass. Using Rezilon as directed also reduces the time and money hay growers would otherwise need to spend on additional herbicide applications.

Rezilon herbicide has long-lasting residual activity for extended control of weeds throughout the season. For best results, it should be applied well before weed emergence. Once applied, Rezilon can sit on the soil surface for some time with no degradation from sunlight while waiting on rainfall for activation.

On Tuesday, August 11, 2020, Bayer will host a panel of regional experts for a live online discussion about how Rezilon offers consistent, long-term weed control for increased hay production and quality. The live discussion will take place from 9 a.m. to 11:30 a.m. Central time. Join the webinar here.

First sales of Rezilon herbicide are anticipated in August 2020 following state registrations.
