Abstract:
A field experiment was conducted during kharif 2019 in medium red soil under irrigated conditions in order to find out the effective fungicide for control of the Alternaria leaf spot of bottle gourd caused by A. cucumerina. Among the six fungicides and one bioagent tested viz, Mancozeb, Propineb, Hexaconzole, Propiconozole, Tebuconazole, Captan + hexaconozole, Trichoderma harzianum, hexaconozole @ 0.1 % recorded least PDI (23.60) followed by propiconozole @ 0.05 % (24.84). With respect to per cent disease reduction over control, maximum disease reduction was recorded by hexaconozole @ 0.1 % (55.21 %) followed by propiconozole @ 0.05 % (52.86 %). The least PDI was noticed in Trichoderma harzianum @ 0.5 % (34.81%). The data with respect to yield revealed that maximum yield (15.78t/ha) was also recorded in case of propiconozole @ 0.05 per cent, with the B C ratio 2.38 followed by hexaconozole @ 0.1 per cent (14.23t/ha) with B C ratio 2.06.
