Effect of Plant Bed, Prebedding Air, and Fungicide Dip Temperature in Controlling Scurf on Sweetpotatoes. Robert H.

Plant bed temp exerts a marked influence on the effectiveness of fungicide dips and on the incidence of scurf developing on sweetpotatoes. Scurf was most severe and the dip treatments less effective on plants developing from sprouts grown in cool beds (24 C). Increasing the temp of the fungicide dip also improved significantly the effectiveness of the treatment in controlling this disease. Air treatments of the duration used (1 to 4 days at 40.5 C) were of doubtful value.
