EFFECT OF FUNGICIDES, MICROBIAL ANTAGONISTS AND OILCAKES IN THE CONTROL OF FUSARIUM SOLANI, THE CAUSE OF SEED ROT, SEEDLING AND ROOT INFECTION OF BOTTLE GOURD, BITTER GOURD AND CUCUMBER
NASREEN SULTANA1
AND A. GHAFFAR2
Abstract: The effect of fungicides, microbial antagonists and
oilcakes in the control of Fusarium solani the cause of
seed rot, seedling and root infection on bottle gourd, bitter gourd and
cucumber was studied In vitro and In vivo. Complete
inhibition of colony growth of F. solani was observed where
fungicides viz., Aliette, Benlate and Carbendazim @ 100 ppm were used.
Carbendazim completely eradicated seed borne infection of F.
solani in bitter gourd and gave maximum reduction in cucumber and
bottle gourd. Root infection was completely checked by Benlate and
Carbendazim in bitter gourd and was best controlled by Aliette, Topsin-M
and Carbendazim in bottle gourd and cucumber. F. solani
infested seeds of bottle gourd, cucumber and bitter gourd reduced
seedling mortality and root infection when sown in mustard and neem cake
amended soil. Mustard cake was found most effective at all
ratios followed by neem and castor cake. 1Crop Disease Research Institute, PARC, Karachi University Campus, Karachi-75270, Pakistan 2Department of Botany, University of Karachi, Karachi- 75270, Pakistan |
