Abstract :
A study on assay of potential of chitinolytic bacterial isolates to inhibit the growth of Rhizoctonia solanicausal agent of damping-off on potato plants has been conducted in Laboratory of Observation Pest and Disease, Medan Johor, UPT. Protection of Crops and Holticulture 1 and Laboratory of Microbiology, Department of Biology, Faculty of Mathematic and Natural Science ofSumatera Utara University, Medan. Two out of six isolatesof chitinolytic bacteria showed to inhibitof R. solanigrowth. The most effective isolates to inhibit the growth of R. solani was Enterobacter sp. BK15 and Bacillus sp. BK13 inhibited the fungal growth with inhibition zone of 2.05 and 2.35 cm, respectively. These two isolates also showed to be able to reduce fungal infection by 31.25% and 37.5%,respectively.
