Abstract:
Management of pomegranate anthracnose has been critical and essential part of cultivation in every pomegranate orchard. Often this fungal disease management was done using fungicides as no resistant cultivars are available. But frequent sprays of fungicides have posed threats of high fungicide resides. Hence, the present investigation was undertaken to evaluate the new and novel fungicide (combi product) molecule with two different modes of action along with already recommended single mode of action fungicides. The experiment was done for two years and found that foliar spray of Aoxystrobin 8.3%+Mancozeb 66.7 percent at 3.5 gm/l was most effective with lowest mean Percent Disease Index (PDI) of 4.90 percent. This treatment also had the highest disease control (88.5%) compared to other treatments. Same fungicide at 3 g/l was also found effective and on par with 3.5 g/l dosage. This fungicide is of dual mode of action and has an advantage of delaying the development of resistance by the pathogen towards the fungicide. Due to its dual mode of action the spray frequencies will also get reduced due to prolonged effect of the fungicide. Foliar spry of Azoxystrobin 23 percent SC was also on par with the Aoxystrobin 8.3%+Mancozeb 66.7 percent but the cost benefit analysis showed that spraying of Aoxystrobin 8.3%+Mancozeb 66.7 percent would be most economical with maximum returns with an additional advantage of prolonged effect and avoiding the fungicide residues in the fruits with reduced number of sprays.
