The three years pooled results revealed that the treatment with azoxystrobin 0.1% showed the least disease intensity (2.70 PDI) with maximum disease reduction (86.72 %) but it was at par with difenoconazole 0.1% (3.46 PDI and 82.98 % PDR) and iprodine + carbendazim 0.1% (4.00 PDI and 80.32 PDR) and were found significantly superior over rest of the treatments. The maximum yield of flower stalks and salable bulbs were obtained in azoxystrobin 0.1% (8.40 lakh flower stalks/ha. and 23.6 lakh bulb/ha.), iprodine + carbendazim 0.1% (8.37 lakh flower stalks/ha. and 24.47 lakh bulbs/ha.) and difenoconazole 0.1% (8.28 lakh flower stalk/ha. and 23.55 lakh bulbs/ha.). The different treatments gave monetary returns ranging from Rs. 18.44 lakh/ha. to 20.60 lakh/ha. as against Rs. 15.83 lakh/ha. in control. The highest monetary returns of Rs. 20.60 lakh/ha. with maximum benefit cost ratio 3.47 was obtained in sprays with iprodine + carbendazim 0.1%.

Key words: Percent disease intensity (PDI), Percent disease reduction (PDR)
