In the present studies the antagonistic microorganisms and antibiotics were tested for their efficiency in inhibition of growth of Xanthomonas axonopodis pv. punicae, the incetant of bacterial blight of pomegranate. Among the different isolates of bioagents, Pseudomonas florescens (Pf4) was found significantly superior in inhibiting (15.73 mm) the growth of X. a. pv. punicae but remained on par with Bacillus subtilis isolates BS1 and BS2 with 12.1 and 13.66 mm, respectively. Whereas bioagents BS3 and Pf6 showed lower inhibitory zone of 0.76 and0.93 mm, respectively. The isolates of bioagents BS 4, Tv-16, Tv-R, Th-10 and Th-R recorded zero inhibition zone. Differences among the treatments and concentrations were found to be statistically significant except between streptocycline and streptocycline + CuSO4. Among them, streptocycline was found to be the best and was significantly superior from the rest of the chemicals with mean inhibition zone of 25.75 mm in all the tested concentrations, followed by streptocycline + CuSO4 (20.24) and bactinash-200 (11.74). Among different concentrations, 1000 ppm recorded the mean maximum inhibition zone (11.33 mm) followed by 750 and 500 ppm. Whereas the least inhibition was observed at 250 ppm (8.33 mm).Keywords

Bacterial blight caused by Xanthomonas axonopodis pv. punicae is the devastating disease of pomegranate. The pathogen strains were collected from predominant pomegranate growing areas of Karnataka to understand the existence of biochemical variability among the different isolates. Among 3 strains (Xap1-Raichur , Xap2- Bellary, Xap3-Koppal) Xap1 showed maximum starch hydrolysis, Xap3 liquified maximum gelatin and all the strains showed positive reaction for ammonia production , H2S production, protein digestion. All the strains showed negative reactions for indole production, voges-poskaure test, nitrate reduction and methyl red test.Keywords

Six antibiotics, two antibacterial chemicals and five bio-agents were evaluated by in vitro against Xanthomonas axonopodis pv. citri (Hasse). Among the different antibiotics and antibacterial chemicals, Streptocycline (10.84 mm) and copper oxychloride (7.50 mm) showed maximum inhibition zone followed by K cycline (9.68 mm). Among the bio-agents, Bacillus subtilis was effective with the inhibition zone of (16.16 mm) followed by Pseudomonas fluorescens (14.63 mm). The fungal bio control agents viz., Trichoderma viride and Trichoderma harzianum were found totally in effective against the pathogen.Keywords
