EFFICACY OF DIFFERENT PROTECTIVE FUNGICIDES AGAINST CERCOSPORA LEAF SPOT OF MUNGBEAN (VIGNA RADIATA L. WILCZEK)

Abstract

The experiment was planned to minimize the losses in mungbean against Cercospora leaf spot disease caused by Cercospora canescens Ellis & Martin. For this purpose a mungbean susceptible line was sown in three sets with three replications and four treatments i.e. Propineb (Antracol), Metalaxl+Mancozeb (Ridomil Gold), Mancozeb and Water as control. After fungicides spray artificial inoculation of C. canescens was given to three sets with 5 days interval to create disease epidemic. Results showed that all the protective fungicides reduced the incidence and severity percentages of Cercospora leaf spot. In particular Ridomil Gold and Antracol shown better results but Ridomil Gold was the best among all which substantially reduces the number of infected leaves and lesions on foliage and pods. It was also found that Ridomil Gold gave best results where it was sprayed within 10 days of infection (on Set I). It managed disease at 18.51% disease index which was much less than the untreated block where disease index was 40.74%.
