Abstract

The effect of plant extracts on leaf rust, Puccinia purpurea of jowar were studied under field condition in Kharif season 2017. Field application of plant extracts gave effective control on jowar leaf rust disease. Azadirachta indica Juss and Calotropis gigantea L were the most effective treatments gave least percent disease index of 12.18 was recorded in T2 followed by T3 recorded 14.09 percent respectively. Least percent disease control of 75.29 percent was recorded in T2 followed by T3 and recorded 71.35 percent. Foliar spray with all plant extracts significantly reduced the percent disease index (PDI). Application of higher concentrations of the extracts showed better disease control. All the treatments were significantly superior to untreated control. Hexaconazole (0.05%) showed complete protection against rust disease incidence in field trials.
