Damping-off of cotton seedlings (caused by the fungus Rhizoctonia solara Kuehn) can be a serious seedling disease in the interior valleys of southern California. Pythium spp. may cause some seed rot and seedling decline. Mercury fungicides were recently banned from use as cotton seed treatments and trials were initiated in the spring of 1970 to find effective replacements.
