The pooled results over three years revealed that the least disease incidence (3.58, 5.55 and 7.22 PDI) and maximum disease reduction (94.67%, 91.74% and 89.26 % ) was recorded in pre storage hot water treatment of corm (50oC for 30 min.) followed by pre planting corm treatment with captan 0.2% + carbendazim 0.2% followed by corm treatment with T. harzianum 10g/l for 30 min., pre storage hot water treatment of corm (50oC for 30 min.) followed by pre planting corm treatment with captan 0.2% + carbendazim 0.2% and pre storage and pre planting corm treatment with captan 0.3% respectively and were found at par with each other.
However, the pre storage and pre planting corm treatment with captan 0.3% gave maximum benefit cost ratio (1.90) and maximum monetary returns per ha.(Rs. 13.21 lakh) and was found cost effective for better management of Fusarium wilt of gladiolus. The other two treatments failed to give good benefit cost ratio due to the higher cost of the fungicides.
