Waterhemp has become very common throughout the area. This weed has a very massive stem and root system. We do have a few options to control this tough weed. The number 1 way is putting a good pre emerge herbicide down. The Xtend weed control system will be key to killing this sometimes glyphosate resistant weed. I have noticed the deluxe adjuvant packages like Plexus and Veracty II Elite make Roundup applications much more effective as well.
