Abstract

Two strains of Trichoderma harzianum Rifai. were tested as biological control agents against blue stain fungus (Botryodiplodia theobromae Pat.) under laboratory condition. Agar method was conducted to measure the growth of stain fungus. Steriled spore suspension was prepared by washing off the surface of Trichoderma plate with distilled water. The result showed that soluble metabolites in the suspension of each strain of T. harzianum which was incubated for 3 weeks in agariculture B did indeed slow the growth of stain fungus for 3 days. Rubber wood samples were dipped in the suspension of each strain which was incubated for 4 weeks in agar culture A. It showed that the test samples were less stained than control samples for 5 days. It also showed that aerial mycelia of both strains of T. harzianum produced high amount of spore when they were incubated on each agar culture for 3 weeks at room temperature.
