| description | Phytophthora palmivora (But 1.) Butler is known to be a
variable or ganism and is considered to be one of the most
destructive pathogens of cocoa and durian which are being
inter cropped in Malaysia. Studies were under taken to compare the
cultural characteristics, sexuality, and pathogenicity of six
Phytophthora isolates from these crops as well as the in-vitro and
in-vivo efficacy of fungicide s against the pathogen. Preliminary
studies on the use of a bio-control agent against the organism
were also looked into.
Cultural studies established that the Phytophthora isolates
belonged to MFI P. palmivora. They produced stellate and striate colonies on carrot, cornmeal, and V-8 juice agar media. Mycelial
growth was opt imum at 28 + 1.5C. No growth occurred at 36C.
Sporangia were caducous, with length: breadth ratios from 1.22 to
1.8 and possessed short, occluded pedicels. Abundant
chlamydospores were produced in culture. |
