| Abstract: | Delayed sprouting and white rot of leaf tips were found on Chinese chives in a greenhouse in Hokkaido, Japan, in the spring of 2006 and 2007. The causal fungus was identified as Rhizoctonia solani anastomosis group (AG)-2-1 and discriminated from the leaf rot pathogen R. solani AG-4 HG-I in terms of pathogenicity. Symptoms and the time of year that the disease occurs also apparently differ for the two pathogens. This is the first report of white leaf rot on Chinese chive caused by R. solani AG-2-1. |
