Fusarium
wilt of banana is a very important fungus that caused the destruction of banana
trees in the tropical countries. Biological control is an alternative method to
control fusarium wilt diseases such as Trichoderma has been known to be
particularly active in the control of the plant pathogens. This study aimed to
evaluate the ability Trichoderma isolates from suppressive soils in
suppress Fusarium wilt of banana in vitro. Thirty one of Trichoderma
isolates were tested their ability to inhibit the growth of FocTR4 LJ27
strain. The isolates were screened in vitro by volatile compounds tested
of Trichoderma isolates against LJ27 strain. Then eight Trichoderma
spp. strains (TR10, T10v1, T1, Tveg2, TR102, TL5, Tveg1, T26) was produced the
high toxic metabolites with strong activity against LJ27 strain, inhibiting the
mycelia growth by 50.33%, 51.33%, 51.67%, 69%, 70.67%, 71.33%, 78%, 96%
respectively. The result indicated to a high efficacy of T. parareesei
T26 for inhibiting the growth of FocTR4. But five isolates of Trichoderma
such as T. brevicompactum (TL7), T. reesei (T658, TL102, and
TL13552), and T. harzianum (TL21) were showing the very low effect on
FocTR4. The volatile compounds can produce for the inhibiting of developing of FocTR4
in vitro. This improves the high efficacy of Trichoderma to use
as alternative methods in reducing the synthetic chemicals that are causing a
toxic pollution for our environment.
