Sawpalmetto (Serenoa repens (Bartr.)Small) is the major shrub on Florida range, and both mechanical and chemical control have been less than satisfactory. At best plant kill with tandem chopping has been about 80% while herbicidal kill has been about 75%. The purpose of this work was to improve mechanical control of saw palmetto by burning (vs.not burning) the plant in February, and chopping in June and December. Possible improved chemical control was evaluated with the herbicide, tebuthiuron (N-(5(1,1-Dimethyl)-1,3,4-thiadiazol-2 yl) N,N-dimethylurea), which was applied at 0, 1.7, 3.4, 6.7 kg/ha (active) before chopping in both June and December. Control of palmetto may be made easier by burning before chopping due to removal of accumlated phytomass, but no difference in palmetto control (P<0.05) was found between burn and no burn. Chopping in June or December resulted in similar palmetto control, and yields of creeping bluestem (Schizachyrium stoloniferum), other grasses, forbs, and shrubs. When compared to no chopping, both June and December treatments resulted in significantly greater palmetto kill, palmetto cover, and yield of other grasses, forbs, and shrubs. Tebuthiuron was ineffective at reducing the number of palmetto plants, but palmetto cover declined (P<0.05), while yield of other grasses increased (P<0.05) as rate of tebuthiuron increased. Palmetto cover and forb yield depended on both burning and herbicide rates. Two years after treatment, average palmetto cover in the 0 and 3.4 kg/ha herbicide treatments was 6.6 and 5.1% in the burn area and 23.0 and 33.8% in unburned areas. Forb yield decreased as tebuthiuron rate increased. Forb yield was lower (P<0.05%) on burned areas (660kg/ha) as compared to unburned areas (1720 kg/ha) at the 0 kg/ha tebuthiuron rate...Although statistical validation could not be made, data and yield observations suggested that better kill was obtained by chopping burned plants because of better plant and soil disruption by the chopper. Tebuthiuron was ineffective in the control of saw palmetto at rates from 1.7 to 6.7 kg(active)/ha.
