Siemer, Former Research Assistant, Department of Botany and Plant Pathology, Oregon State University, Corvallis 97331, Present address of senior author: Agricultural and Veterinary Products Division, Agricultural and Veterinary Products Division, Abbott Laboratories, 2035 E.

Data are presented showing close agreement between a root disease rating system and the tension required to pull bean plants from the ground by means of a spring scale coupled to visegrip pliers. Where applicable, this method is capable of quantitative measurements of anchorage and disease with significant time savings and greater reliability than is possible by any subjective method.
