SUMMARY:

Three trials at two locations were conducted to evaluate sweet corn hybrids for performance under root rot conditions. While both sugar/se and supersweet sweet corn hybrids were evaluated, the emphasis was again on identifying supersweet hybrids with improved tolerance to root rot.

Objectives:

VegNet is a regional pest monitoring and reporting network serving the Oregon processed vegetable industry, managed by the OSU Extension Service, and funded by the Oregon Processed Vegetable Commission. In the early spring of 2007, a variety of insect traps were placed on cooperating farms in vegetable production areas around the Willamette Basin and maintained during the growing season.

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 (biofungicides) and chemical treatments for suppression of sweet corn seed rot/damping-off, root rot, and crown rot.Objective 3: Cooperate with other sweet corn projects (cultivar screenings, etc.) within and outside of OSU programs.
