Research Effects of Growth Regulators and Nematodes on Cylindrocladium Black Root Rot of Soybean. B. A. Fortnum, Assistant Professor, Department of Plant Pathology and Physiology, Clemson University, Clemson, SC 29631. S. A. Lewis, Associate Professor, Department of Plant Pathology and Physiology, Clemson University, Clemson, SC 29631. Plant Dis. 67:282-284. Accepted for publication 6 August 1982. Copyright 1983 American Phytopathological Society. DOI: 10.1094/PD-67-282. Meloidogyne incognita, when inoculated on Davis soybean, increased the damage of Cylindrocladium black root rot (CBR) to soybean. Application of ethephon and chlormequat chloride to M. incognita-infected soybean increased the severity of CBR, and severity of CBR in M. incognita-inoculated soybean was related to the time of fungus inoculation. The influence of the M. incognita life cycle on CBR development is discussed. Keyword(s): kinetin, naphthalene acetic acid. |
