Alternaria leaf blight is one of the most important foliar disease of chrysanthemum. It has become major constraint in chrysanthemum growing areas. The fungicides were evaluated under field conditions at College of Horticulture, Hiriyur, during kharif 2016 and 2017. Five sprays were given at 60, 75, 90, 105 and 120 DAS. Two years pooled results revealed that tebuconazole () significantly higher per cent disease control (PDC) of which was followed by tebuconazole+ trifloxystrobin () and propiconazole (). Similarly, the maximum yield of t/ha was recorded in tebuconazole () which was followed by tebuconazole+ trifloxystrobin ( t/ha) and propiconazole ( t/ha) respectively. However, tebuconazole recorded highest benefit:cost of followed by hexaconazole remained as next best fungicide. | Evaluation of new fungicides molecules against leaf blight of chrysanthemum caused by Alternaria spp.
