Field trials were conducted to ascertain the efficacy of three fungicides on leaf spot disease of ginger (Zingiber officianale Rose) at National Root Crop Research Institute, Umudike, Nigeria. The fungicides were marketed as Team (Mancozeb/Carbendazim), Hi-shield (Mancozeb) and Funguran-OH (Copper oxide), and were used as sole and in various combinations for soil and foliar treatment against the disease, using ginger varieties UG1 and UG2, as test crops. The result of the two year 2007 and 2008 trials revealed that the fungicides in their various applications reduced disease severity and increased rhizome yield of the ginger. There was significant difference in the effects of the various fungicide applications, with Team (Mancozeb/ Carbendazim) in both single and combination, showing more efficacy than others. The two ginger varieties equally exhibited significant differences in their susceptibility to the disease, with UG1 having high tolerance to it, giving high rhizome yield, unlike UG2 which was highly susceptible, with low yield.
