Sweet pecan (Carya illinoensis), used for furniture and panelling, was planted in Mississippi in Feb. 1971 and plots mowed, disced or left untreated. Damage by O. cingulata was assessed in 1979. Fifty five per cent of trees were damaged in disced, 40% in mowed plots and 19% in control plots. Trees in disced plots were significantly larger with a greater survival rate.
