Plant and Insect Diagnostic Clinic Update - February 4, 2009


Diseases

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.

The ZZ Plant


The ZZ plant (Zamioculcas zamiifolia) is a tough, easy to grow houseplant. It tolerates low levels of light, prolonged dry periods, and neglect. Plants have few insect or disease problems. Zamioculcas zamiifolia is also known as aroid palm, eternity plant, and fat boy. The ZZ plant is a member of the Arum family. Other houseplants in this family include philodendron, peace lily, and Chinese evergreen. The plant is native to east Africa.

Long-Bodied Cellar Spider


Cobweb is a term used for messy spider webs in homes, the flimsy webs that sort of drape down and get covered in dust. There is a group of spiders we call the cobweb spiders, but many species of spiders make messy webs we would call cobwebs.
