OBJECTIVES
1. To map incidence of Fusarium wilt in
banana major growing areas in Luzon
2. To map the occurrence of the different
races of Foc across regions of Luzon
3. To have repository isolates and herbaria
of Foc
4. To do management of banana against
the disease

A2 – Two promising isolates namely
Aspergillus sp., EF25, EF26 were
able to reduce colony diameter of
Foc isolates

conidia attached to a vesicle

micronematous mycelia

Foc-NV isolates grown alone on agar plates (A-NV2A, D-NV3B,G-NV5C)
compared when grown with Aspergillus sp. EF1 (B, E, H) and Aspergillus
sp. EF25 (C, F, I). Rapid colony forming characteristics of Aspergillus sp.
EF1 completely overgrew Foc isolates, except Aspergillus sp. EF1
against NV2A and NV3B.
Foc-IS isolates grown alone on agar plates (A-IS3B, C-IS5A, E-
IS6B) compared when grown with Aspergillus sp. EF26 (B, D, F).
EF completely covered Foc isolates except Foc-I6B.

restricted growth of Foc- QU2B and Foc-QU3A isolates .
