Research Root Dip Treatments for Controlling Blueberry Stem Blight Caused by Botryosphaeria dothidea in Container-Grown Nursery Plants. W. O. Cline, Researcher, Department of Plant Pathology, North Carolina State University, Raleigh 27695-7616. R. D. Milholland, Professor, Department of Plant Pathology, North Carolina State University, Raleigh 27695-7616. Plant Dis. 76:136-138. Accepted for publication 24 June 1991. Copyright 1992 The American Phytopathological Society. DOI: 10.1094/PD-76-0136. Dipping highbush blueberry roots into a benomyl-kaolin clay slurry at concentrations of 2,000–3,000 ?g/ml resulted in protection against stem blight development caused by Botryosphaeria dothidea. Reduction in lesion development was greatest when kaolin clay was used as the slurry rather than Terra-sorb. Phytotoxicity was observed in plants treated with rates higher than 3,000 ?g/ml. |
