New Rezilon® (indaziflam) herbicide provides better hay quality by controlling summer and winter annual broadleaf weeds and grasses. It is designed to protect desirable grasses and control the unwanted grasses that grow in hayfields, non-irrigation ditchbanks, fire breaks and any sites managed for hay. It also helps support managing annual grasses in perennial grass hay fields, a quality few pre- or post-emergence herbicides are able to maintain. This benefits the entire herbicide market and the prime hay-growing landscape.
For year-round control of broadleaf and annual grass weeds, Rezilon is applied in both late summer and late winter. Applications made immediately after a cutting in August or September will help provide pre-emergence control of fall-emerging weeds, while applications made in January or February will provide pre-emergence control of spring-emerging weeds.
