Plant and Insect Diagnostic Clinic Update - February 4, 2009


Rhizoctonia solani foliar infection was found on Cyclamen submitted to the Plant and Insect Diagnostic clinic. Rhizoctonia spp., most commonly found at the soil line (root rots), can attack stems and leaves as well when plants are grown close together and kept under moist conditions. Entire stock beds or flats can be lost to Rhizoctonia in very short periods of time. Rhizoctonia root rot can be common in begonia, ferns, holly, impatiens, juniper and many others herbaceous and woody ornamentals.
