Weed scientists have officially confirmed the presence of dicamba resistant pigweed in the Mid-South region. The finding is concerning to farmers in the region since many have utilized the dicamba-tolerant Xtend seed technology in recent years to gain better control of the noxious weed, which has developed resistance to other herbicides. Pigweed, or Palmer amaranth, can quickly choke out desired crops and take over fields because of its reproduction rate and growth rate. Farmers continue to be limited in their defenses against the weed. Weed scientists discourage singular approaches to combating weeds, and instead encourage an integrated approach that incorporates a range of actions to keep the weeds at bay.
