As we enter this spring season, many of us are wondering…what will the repercussions be of this past winter’s mild temperatures? While no one really knows definitively if we’ll experience increased insect or disease pressure, we do know we’ll likely have increased winter annual weed pressure in our fields. Last fall’s extended season, along with the warm soil temperatures this spring, have resulted in an increase in marestail population as well as size of marestail rosettes.
Whether you are utilizing a Roundup Ready®, LibertyLink®, or Roundup Ready 2 Xtend® soybean system, it is important to control marestail prior to soybean emergence. Keep your rate of 2,4D at 0.5 to 1 lb. ae/A. in a Roundup Ready or LibertyLink soybean program. If you’re planting Xtend soybeans, utilize labeled dicamba products such as XtendiMax™, Engenia™, or FeXapan™ at a rate of 0.5 lb. ae/A. to ensure adequate marestail burndown. Please remember, season-long weed control cannot be achieved with a sufficient burn down program alone. To remain clean, a solid residual herbicide that matches your specific weed species is also critical to any herbicide program.
