I.UmaN. U.AdekunleA. A.OmamorI. B.102006910Trichoderma viride, T. polysporum,T. hamatum and T. aureoviride were used as potential biological agents for seed treatments against Ceratocystis paradoxa causing black seed rot in oil palm sprouted seeds in vitro. T. polysporum significantly reduced the percentage infection to 13 and 10%, 4 days post inoculation. T. viride 18.3 and 11.7%, T. hamatum 22 and 15%, T. aureoviride 23.7 and 13%, benlate solution 21.7 and 18.3% and control 80 and 30% for wounded and unwounded seeds, respectively. In vivo, the emergence (survival) and the growth of oil palm seedlings from Trichoderma species treated oil palm sprouted seeds were significantly higher than the emergence and the growth observed from the control treatment. C. paradoxa infested seeds had 63 to 71% survival and average seedling heights of 18.4 to 25.1 cm. Seeds without pathogen had 100% survival with average seedling heights of 38.2 to 46.5 cm. The effects of the bioagents were similar or high than the one obtained from benlate solution.]]>Ahmed, S.A.,20012001Anonymous,19651965Baker, R. and T.C.
