Abstract
A study on efficacy of different plant extracts for management of bacterial blight disease of pomegranate caused by Xanthomonas axonopodis pv. punicae was conducted during the year 2011-12 at College of Agriculture, Osmanabad. Plant leaf extract of seven botanicals viz., Shatavari leaf extract, Sadaphuli leaf extract, Adulasa leaf extract, Karanj leaf extract, Ashwagandha leaf extract, Behada leaf extract, Ritha leaf extract @ 10 and 20 per cent were evaluated in vitro by applying inhibition zone technique (paper disc method) and using nutrient agar (N.A.) as basal culture medium. The result revealed that Sadaphuli leaf extract at 10 per cent was found most effective for controlling X. axonopodis pv. punicae by forming 8.22 percent inhibition followed by Ritha leaf extract (6.50%), Adulasa leaf extract (5.35%), Shatavari leaf extract (4.52 %), Karanj leaf extract (4.11%), Ashwagandha leaf extract (4.11 %) and Behada leaf extract (3.28%). Similarly, Sadaphuli leaf extract at 20 per cent was found most effective for controlling X. axonopodis pv. punicae by forming 9.06 percent inhibition followed by Ritha leaf extract (8.22 %), Adulasa leaf extract (6.99 %), Shatavari leaf extract (6.58 %), Karanj leaf extract (5.75 %), Ashwagandha leaf extract (5.36 %) and Behada leaf extract (5.36 %).
