Efficacy of botanical formulations and fungicides against Botryosphaeria dothidea, causing white rot in apple (Malus × domestica Borkh.)
Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 3
Abstract
The present study was conducted to determine inhibitory effect of plant extracts, their botanical formula-tions (BF1 and BF2) and safer fungicides against Botryosphaeria dothidea cause white rot of apple (Malus × domes-tica) during storage. Poisoned food technique was performed to evaluate the efficacy of different plant extracts, their botanical formulations and safer fungicides. Out of twelve botanicals evaluated under in vitro conditions against the white rot pathogen, leaf extract of Ocimum sanctum was found most effective among all the treatments with 54.07 per cent average inhibition in mycelial growth. Out of twelve plants evaluated for their efficacy, six effective plants Karu (Roylea elegans), Artemisia (Artemisia roxburghiana), Neem (Azadirachta indica), Bana (Vitex negundo), Tulsi (Ocimum sanctum) and Darek (Melia azedarach) were selected for making two botanical formulations (BF1 and BF2). While, BF1 was water based formulation and BF2 was cow urine based formulation. Among these botanical formulations, BF2 inhibited mycelial growth of white rot pathogen by 72.70 per cent and BF1 66.37 per cent at 100 % concentration. Whereas, among the tested fungicides, Score at 100 ppm concentration was found to be most effective with 75.01 % average inhibition in mycelial growth of the white rot pathogen.
