Single or Double Application @ 0.2 percent of Tilt, Daconil, Score-250 and Topaz C-50 suppressed the rate of gram blight disease development and reduced AUDPC compared to untreated control. None of the fungicides applied once or twice completely inhibited the symptom development. Score-250 was the most effective fungicide followed by Daconil, Tilt and Topas C-50 in that order, whether applied singly or twice. Except significantly less disease severity in plots of CM-72 receiving double foliar spray of Tilt or Topas C-250, the differences in mean disease severity of most of the treatments (single or double spray) compared to untreated control were statistically not significant. Statistically significant yield enhancement was recorded in plots of Paidar-91 receiving single spray of Daconil. Most of the treatments resulted in positive effects on yield of CM-72, CM-88 and C-727 receiving double spray of fungicides. However, the increases in yield of most of the treatments compared to untreated control or double spray compared to single spray was not significant statistically.
