| description | Large scale hydroponic crop production is a recent entity in
Malaysia with University of Agriculture Malaysia (UPM) playing a lead role in research and development. Since its inception in 1982,
pre- and post-emergent damping-off in cucumber, muskmelon and tomato
seedlings had been frequently observed. Pythium spp. were also
isolated from roots of wilted mature cucumber, muskmelon and tomato
plants at UPM hydroponic, at Malaysia Agricultural Research and
Development Institute (MARDI) and at FIMA hydroponic in Fraser's
Hill. The mature muskmelon plants exhibited drastic interveinal
chlorosis and yellowing of young and old leaves at the onset of fruiting and was accompanied by general necrosis of the root system
resulting in subsequent plant death. Isolation of Pythium implicate
them to be the causal agent. Since little is known about their role
and control in the hydroponic system in Malaysia, studies were
undertaken to characterize and identify the Pythium spp., to
establish their pathogenicity, to determine the sources of inoculum,
as well as to investigate the in-vitro and in-vivo efficacy of some
fungicides in their control. Through cultural and morphological studies, three Pythium spp.
namely P. myriotylum, P. splendens and a non-sporulating Pythium Spa
were identified from six isolates obtained. |
