Abstract
Isolates of Pythium obtained from diseased caladium [Caladium hortulanum] roots were identified as P. irregulare, P. myriotylum and P. splendens. Pathogenicity studies with these species of Pythium at 24.degree. C and 32.degree. C showed P. myriotylum and P. splendens to be infective. The shoot, corm, root and total plant weights after 40 days showed that only P. myritylum reduced plant growth significantly (P < 0.05) at 32.degree. C. No significant differences (P < 0.05) were noted for any of the species at 24.degree. C. Greenhouse inoculations with P. myriotylum significantly slowed (P < 0.05) the germination of corm pieces and resulted in significant losses (P < 0.01) in total plant growth after 28 wk.
