Cotton (Texas) Root RotOlsen, Mary W. 05 1900 (has links)
4 pp. / Cotton root rot commonly causes a sudden wilt and death of susceptible plants in summer months but may also cause a slow decline, especially at cooler temperatures. So, positive identification of disease by an experienced person is essential. This publication addresses the symptoms, environmental conditions, disease, prevention and control methods, sampling, identifying susceptible plants and the tolerant and immune plants of cotton root rot.

Red Raspberry Root Rot in Northern UtahPowelson, Robert L. 01 May 1956 (has links)
During the last few years, red raspberry growers in Utah have been finding that plantings gradually lose vigor and are not profitable. In the largest raspberry growing area in Utah, Utah County, figures taken from the U.S. census from 1930 to 1950, show a decrease in acres of raspberries grown from 401 in 1930 to 190 in 1950 (2). In many instances this deterioration of raspberry plantings in Utah has not been definitely associated with known plant pathogenic fungi or virus infections. Neither can the expansion of suburbs account for this decrease. In certain cases it has been obvious that other factors were involved. Since attention had already been directed to above-ground symptoms, the next logical step was to exam in the roots.
