Peanut seedlings expressed stunt, wilt, and necrosis 6 days after inoculation with Pythium myriotylum zoospores. The amount of seedling disease was positively and significantly correlated with the degree of Pythium pod rot in maturing plants of peanut genotypes PI 365553, PI 378012, Toalson, Tamnut 74, and Florunner.
