RHIZOCTONIA DISEASE IN PROPAGATION MATERIAL AND FIELD GROWN STRAWBERRY
Plants inoculated with Rhizoctonia prior to planting in the field showed that Rhizoctonia can grow along the runners for at least 40 cm from the point of Inoculation. In a field trial, the performance of locally grown strawberry plants was compared with that of plants from meristem culture. The local plants showed poorer growth. Inoculation with certain Rhizoctonia isolates decreased plant growth and yield, while other isolates increased them.
It is concluded that Rhizoctonia is a serious pathogen of strawberry in Israel. Its control can be achieved through the use of healthy propagation material and soil disinfestation.
