Anthracnose or Gloeosporium fruit rot is one of the most severe
diseases in the fruit production. The causal fungus,
Colletotricum species attacks fruits, flowers, stems and leaves
of crops such as Avocado, Mango, beans, banana, papaya and Guava.
In the pursuit of extending the shelf life of Malaysian fruits
for export purposes, biological control was tried using three
species of Trichoderma. In vitro studies in the laboratory show
that the antagonistic species has potential as biocontrol agents
as they reduce radial growth of cultures, spore germination of 6
species of Colletotricum. These fungi alfo reduced disease
symptoms of anthracnose in infected banana fruits. Antagonistic
action between the fungal hyphae are also observed by the use of
light microscopy
