Abstract
In in vitro evaluation Tilt followed by Rubigon was the most effective fungicide in inhibiting the mycelial growth of Aternaria citri, the cause of stem end rot of kinnow mandarin and lemon. Thiabendazole and Antracol were intermediate while Calixin, Polyram combi, Daconil and Calixin M, were the least effective fungicides. Nimrod was ineffective fungicide in inhibiting mycelial growth of the fungus. Daconil, Thiabendazole, Daconil+Rubigon (in combination of 1:1) were the most and equally effective in controlling stem end rot of kinnow mandarin with dip treatment while Tilt dip treatment was the most effective in controlling stem end rot of lemon fruits. Although there was an increased reduction in percent fruit rot with an increase in Tilt concentration, the lower concentrations of Tilt, which were ineffective for kinnow fruits, were quite effective for controlling stem end rot of lemon fruit
