Abstract
The relationships between the development of disease symptoms ofPuccinia sorghi, Exserohilum turcicum andHelminthosporium maydis on susceptible sweet corn plants, and the water status of the plants, were studied. At a relative water content (RWC) of 75% the development of sori ofP. sorghi, and the leaf area infected byE. turcicum andH. maydis, were inhibited by 38, 75 and 84%, respectively, as compared with the control plants (RWC = 100%).P. sorghi andH. maydis were not inhibited by a slight decrease in the RWC (96%), but development of leaf area infected byE. turcicum was inhibited by 33%.P. sorghi seemed to be better adapted to relatively high water deficiency in the host plants thanH. maydis orE. turcicum.
