Abstract

To evaluate the efficacy of some selected contact, systemic and mixed fungicides against Pestalotia palmarum causal organism of grey leaf spot of coconut. Naturally infected leaf sample of coconut having characteristic symptoms of grey leaf spot diseases was collected from Khulna University campus. The pathogen was isolated, purified and identified as P. palmarum. The fungicides were tested against P. palmarum at 1000, 2000 and 3000 ppm concentrations. All fungicides at all concentrations inhibited the growth of the pathogen and their effect differed significantly (≤ 0.01). No growth was observed in Hexaconazol, Propiconazol, Hepridion and Carbendazim at any concentrations. Mancozeb at all concentrations and Mancozeb+Metalexil at 2000 and 3000 ppm inhibited more than 70%. Mancozeb+Metalexil 1000 ppm inhibited the lowest (60.49%).
