Abstract:
The tuberose (Polianthes tuberosa L.), is one of the most important commercial cut flower and loose flower crop and highly praised favourite flower belongs family Amaryllidaceae which is mainly grown in tropical and subtropical regions of the world. Studies on in vitro evaluation of non-systemic, systemic and combi fungicides against Fusarium equiseti were carried out in the department of Plant Pathology, College of Agriculture, Shivamogga during 2020-2021. Among the non-systemic fungicides evaluated maximum per cent inhibition (100%) was recorded in mancozeb and propineb which was followed by captan (98.32%). Least per cent inhibition of fungus was recorded in chlorothalonil (77.25%). Among the systemic fungicides evaluated maximum per cent inhibition (95.81%) was recorded in hexaconazole followed by tebuconazole (87.71%) and pyraclostrobin (84.37%). Least per cent inhibition was recorded in propiconazole (72.94%). Among the combi products cent per cent inhibition of growth of fungus was recorded in all the combi products like tebuconazole + trifloxystrobin, pyraclostrobin + epoxiconazole, carbendazim + mancozeb and metalaxyl-M + mancozeb and least per cent inhibition of fungus was recorded in propiconazole + difenoconazole (92.32%) against Fusarium equiseti at all the three concentration 250, 500 and 1000 ppm.
