Abstract:
Powdery mildew of chilli is incited by Leveillula taurica is one of the most important diseases of chilli. The present experiment was conducted at College of Agriculture Ganjbasoda during the Rabi season of 2017-18 to evaluate the efficacy of new fungicides against powdery mildew of chilli. A variant with no application of fungicides was used to control. All fungicidal treatments reduced the disease severity as compared to the untreated control with increased yield. Application of Pyriofenone 180SC (700 ml/ha) significantly reduced the disease and recorded the highest yield (138.86 q/ ha)) followed by Pyriofenone 180 Sc (600 ml/ha) with yield135.45 q/ha. The overall results revealed that Pyriofenone 180 Sc at both the concentration (700 ml and 600 ml/ha) effectively reduced the disease severity and increased the yield as compared to untreated control.
