Disease incidence and disease severity of each surveyed locations were observed. Snake gourd field of Instructional Farm, Vellayani recorded a maximum Disease incidence (90.00 per cent) and Percentage disease index (44.22 per cent). The least disease incidence (70.00 per cent) and percentage disease index (21.89 per cent) was recorded for snake gourd fields in Palapoor. Mophological studies the five isolates C1,C2,C3 and C5 were larger in size and cylindrical shape with obtuse ends while isolate C4 was smaller in size and ellipsoidal in shape.
