Trichoderma harzianum, isolate T 01-22, was cultured on either sorghum grains, ground mesocarp fibre of oil-palm or oil-palm shell, both amended with urea fertilizer (100:1, w/w). T. harzianumcultured on ground mesocarp fibre was then used to coat seeds of Chinese kale (Brassica alboglabraBailey) to control damping-off of seedlings caused by Pythium aphanidermatum. Biomass of T. harzianumcultured on ground mesocarp fibre of oil-palm was more effective than Captan and Benomyl, but less effective than Metalaxyl, in controlling damping-off of Chinese kale seedlings. Viability of T. harzianumgrowing on sorghum grains was reduced significantly during 7 months storage, followed by that of T. harzianumcultured on ground mesocarp fibre and oil-palm shell, both amended with urea fertilizer (46-0-0) at 100:1 (w/w). |
