To evaluate procedures measuring ''partial physiological resistance'' as a supplement to field inoculation. To investigate the relationship of juvenile soybean sensitivity to disease severity ratings developed using field techniques. Field studies in Ohio, Michigan, Wisconsin and Minnesota were conducted with locally-adapted culitvars and planting techniques. Some cultivars and techniques were common to all states. Data was collected on plots sprayed with inoculum versus natural inflection, soybeans grown in various row widths and crop rotations, and for various commercial soybean cultivars.
White mold is an increasing problem in the North Central States.
This project was funded to develop basic information that could be used to develop grower recommendations to minimize the damage from white mold.
