| Abstract/Contents: | "Large patch on turfgrass is caused by the fungus Rhizoctonia solani and is a common disease that afflicts warm season grasses all over the world. Despite how common this disease is, the effectiveness of modern fungicides has created gaps in research on the management of large patch. Lab research was initiated 3 June 2022 in Raleigh, NC (NC State Varsity Research Lab) in order to determine temperatures influence on the pathogenicity and growth rate of Rhizoctonia large patch isolates. We isolated five different samples from various infected grass species and plated them on PDA media. We incubated three replicates of each isolate 18.3,21.1,23.9 and 26.7°C and measured their hyphal growth every five days. We found that 23.9C and 26.7C had the greatest rate of growth with almost every isolate filling the media plate by the tenth day. 18.3C and 21.1C suppressed hyphal growth never reaching above 25mm over the 15 days measured. None of the isolates received full suppression at any temperature and had at least a small measure of hyphal growth. We will study the effect of temperature on more isolates then compare our result from both studies to see if they match what we expect from out field trials. Large patch is being reported more often in the southeast USA and is expected to become more prevalent due to climate change. It is important to study how temperature effects disease progress to better know when to manage this disease as climate change alters its growth patterns." |
