Disease Caused by Phytium Spp. on Selected Crops Grown Under Hydroponic Culture System and Their Control

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 obse...
