When applied as a pre-emergence herbicide, Boundary 6.5 EC fits under any trait platform, making it a flexible choice for a variety of soybean production systems. It offers extended residual control of up to five weeks, providing growers with a critical window of weed-free conditions during the early stages of crop development. Boundary 6.5 EC delivers proven protection against 32 broadleaf weeds and early-season grass weeds, including some of the toughest and most yield-robbing species such as pigweed, lambsquarters, and foxtails.

With two active ingredients—metolachlor and metribuzin—it combines two modes of action to help manage herbicide resistance and improve long-term weed control. Its versatility makes it effective across different soil types and tillage systems, and it works especially well as part of an integrated weed management plan. By reducing early weed competition, Boundary 6.5 EC helps promote stronger crop stands, better use of nutrients and moisture, and ultimately greater yield potential.
