Effect of Air and Growing Medium Temperatures on Rhizoctonia Foot Rot of Epipremnum aureum

A. R. Chase,R. T. Poole-1990-09-01-Journal of Environmental Horticulture

TL;DRAbstract

Abstract Air and growing medium temperatures affected severity of foot rot of Epipremnum aureum (pothos) caused by Rhizoctonia solani AG4. Maximum daily temperatures of 30°C (86°F) for either air or soil resulted in optimal disease development. Maximum daily temperatures of 35°C (95°F) decreased disease development significantly due to fungal pathogen growth reduction. A continuous temperature of 30°C (86°F) was also too high for significant disease development.
