Formulation of Effective Chemical Management Strategy against Cercospora Leaf Spot Disease of Chilli

Field experiment was conducted during 2015 and 2016 to find out effective chemical management strategy against one most common disease of Chilli, which occurred throughout the year, i.e., Cercospora leaf spot. Among the six different fungicides treatments tested for spraying. All the treatments showed significantly different results than check. Lowest disease severity was found in Pyraclostrobin + Tebuconazole (Double application) (7.85%). The highest percent disease control was observed with Pyraclostrobin + Tebuconazole (Double application) showing 64.69% disease control followed by Pyraclostrobin + Tebuconazole (Single application) (61%) and Azoxystrobin + Tebuconazole (Double application) (57.98%). The treatment Azoxystrobin + Tebuconazole (Single application) also showed good control over Cercospora leaf spot of Chilli. Considering the yield, highest yield was obtained under Pyraclostrobin + Tebuconazole (Double application) with the estimated production of 1650.55 Kg/ha followed by Pyraclostrobin + Tebuconazole (Single application) and Azoxystrobin + Tebuconazole (Double application) with the production of 1285Kg/ha and 1080 Kg/ha, respectively. Among the treatments, Chlorothalonil (Double application) showed lowest disease control as well as lowest yield.
