Herbicide Plantback Restrictions

A very useful table was developed by researchers Hanson, Rauch, and Thill at the University of Idaho to help farmers with herbicide selections. PNW Publication 571 Plantback Restrictions for Herbicides Used in the Dryland Wheat Production Areas of the Pacific Northwest contains a color-coded table listing plantback restrictions for a wide array of herbicides and crops used in this region. The publication also discusses factors that contribute to the carry-over of herbicides.

PNW 571 is available in an easily printable format (pdf) at:
