Title: Developing Techniques for Evaluating the Susceptibility of Root-disease
Objective 1: Evaluation of commercial sweet corn varieties and inbred germplasm in small plots for susceptibility to seed rot/damping-off as well as root, stalk, and crown rot. Objective 2: Evaluation of microbial and chemical treatments for suppression of sweet corn seed rot/damping-off, root rot, and crown rot. Objective 3: Cooperate...
