Abstract

Among fungal diseases anthracnose caused by Colleotrichum gloeosporioides is the most important disease. Survey of pomegranate (Punica granatum) orchards was conducted during 2013–14 in all the cropping seasons viz. mrig bahar, Hastabar and ambia bahar to assess the incidence and severity of anthracnose on pomegranate in Aurangabad, Jalna, Beed Osmanabad, Latur, Nanded, Hingoli and Parbhaani district of Marathwada region of Maharashtra state. The per cent disease incidence (PDI) and disease severity were recorded using 0–5 point scale. The maximum PDI on leaf was recorded in Hingoli (24.04%) followed by Nanded (22.62%) and Parbhani (22.22%) while least PDI recorded in Aurangabaad (15.09%). On fruit maximum PDI recorded in Parbhani (28.80%) which least in Beed district (19.02%). The 9.83 per cent disease variety on leaf was observed in Hingoli district and 10.70 per cent on fruit in Parbhani district. The maximum PDI (27.44%) on fruit and disease severity 12.45 per cent on fruit was recorded in Arakata. The maximum mean PDI 21.30 per cent on leaf and 25.85 per cent on fruit was recorded on trees aged above 5 years. The highest per cent disease incidence 25.34 per cent on leaf and 26.78 per cent on fruit was recorded on mrig bahar and the highest disease severity of leaf 10.05 per cent and fruit 11.22 per cent was reocrded in mrig bahar.
