Against Tough Weeds

Decorative Shape

Over the past 25 years, the number of resistant weed species has spread across the U.S., making weed resistance management a top priority for growers.

In fact, the number of multiple-herbicide resistant weed species has increased 175% since the year 2000.*

Once herbicide resistance arrives, the cost to achieve effective weed control increases, so it’s more profitable to manage weeds before they become resistant.
