Abstract

Studies from 1985 to 1989 showed that disking 3, 7, 10, 14, or 30 d after applying chlorsulfuron, clopyralid, dicamba, glyphosate, picloram, or 2,4-D did not improve Canada thistle control in uncropped, dryland fields. Disking after a fall or after a fall plus a spring herbicide application did not influence Canada thistle control for any herbicide regardless of the time of herbicide application or the time between application and disking.
