Brief Project Summary:

This study evaluates the performance of several residual pre-plant herbicides and mixtures in the control of Palmer amaranth, as well as strategies to extend length of control. Previous research indicates further measures will need to be implemented to adequately control Palmer, including follow-up residual herbicides applied four to five weeks after planting and timely application of post-emergent herbicide treatments. Growers are encouraged to use multiple control methods, such as tillage, cover crops, rotating modes of action, rotating crops, cleaning equipment between infested fields and even hand pulling isolated weeds.
