Effect of Chloropicrin, Vapam, and Herbicides for the Control of Purple Nutsede in Southern Pine Seedbeds

Methyl bromide (MBr) controls purple and yellow nutsedge (Cypenrs rotundus L. and C. esculentus L.) better than other soil fumigants. Chloropicrin is a good alternative to MBr for enhancing seedling growth but is inferior as a herbicide (South and others 1997). Nutsedge control with chloropicrin has been increased by adding Vapam (metham) or selective herbicides such as Eptam (Carey 1997). In this trial, loblolly (Pinus faeda) and slash pine (Pinus elliotti production and growth, were measured and the number of nutsedge tubers were counted. Fumigated plots (chloropicrin or chloropicrin plus Vapam) were treated with either Tillam (pebulate), Eptarn (EPTC) or Manage (halosulfuron).
