Abstract:
An experiment was carried out to study efficacy of differentantibacterial antibiotic, plant extracts and bioagents against bacterialblight of soybean caused by Pseudomonas syringae pv. glycinea. Theresults revealed that all the five antibiotics tested in vitro applyingpoisoned food technique against Pseudomonas syringae significantlyinhibited the growth of the test pathogen over untreatedcontrol. However, antibiotic, Streptocycline + Copper oxychloriderecorded minimum mean colony diameter (10.47mm) and maximummean inhibition (83.65 mm) of growth of the test pathogen overuntreated control (mean col. dia. 90.00 mm and mean inhibition,0.00) followed by the antibiotic Streptocycline 100 ppm (mean col.dia., 15.64 mm and mean inhibition, 76.69%) and Copper oxycloride(mean col. dia., 21.42 mm and mean inhibition, 62.74%). In field, thehighest mean per cent disease incidence 35.51 per cent was observedin poushamycin treatment. The lowest mean per cent diseaseincidence 12.74 per cent was found in treatment streptocycline 100ppm + Copper oxychloride (@0.25%) and recorded highest seed yield(2605 kg/ha) and test weight (14.33 g). Plant leaf extract (@ 5 and10%) of Neem recorded lowest mean colony diameter (34.72 mm)and highest mean mycelial growth inhibition (59.26%) of the testpathogen over untreated control followed by Ginger (mean col. dia,44.42 mm and mean inhibition, 48.55%).
