Among the five fungicides (Copper-Oxy-Chloride, Mancozeb, Thiophanate Methyl, Metalaxyl, and Carbendazim), tested for the control of Phyllosticta leaf spot of ginger, Carbendazim (0.1%) three sprays, starting with the first symptoms appearance in the field followed by two more sprays at monthly interval, was found more effective in reducing the severity of the diseases (21.3%) that consequently increased the fresh rhizome yield (173.0 q/ha) significantly, followed by Metalaxyl (118.0 q/ha) and Thiophanate Methyl (116.0 q/ha), respectively. Mean apparent rate of infection (ARI) was also the lowest in Carbendazim (0.1%) spray.
