Abstract
Cultural and mechanical methods are viable options for inclusion in any weed control program. Selection of weed control methods is determined by crop, cost, desired yield, weather, and labor availability. Yellow and purple nutsedge (Cyperus esculentus L. # CYPES and C. rotundus L. # CYPRO) have proliferated as production inputs have intensified. Nutsedge densities have increased largely due to reduced competition as better annual weed control and improved growing conditions have resulted.
