Studies were conducted in 2016 and 2017 to evaluate the effect of various rates of diclosulam on yellow nutsedge tuber production. Single pre-sprouted purple nutsedge tubers were transplanted into outdoor microplots and treated after six weeks of growth with six rates of diclosulam (1.7 to 53 g ai ha-I) POST and a nontreated control. All shoots emerged at the time of application were marked with plastic rings; this allowed for classification of tubers at exhumation of 1) tubers attached to shoots that were emerged at time of application, 2) tubers attached to shoots that emerged after application, and 3) tubers without an aerial shoot during the study.
