Integrated disease management practices like selection of disease free seedlings, use of organics, proper spacing, pruning time, method of pruning, sanitation, sufficient rest after harvest and use of antibiotics with copper fungicides have proven well in reducing the severity of bacterial blight of pomegranate. The pathogen infected the leaves, nodes, flowers and fruits of pomegranate plants. Leaf blight is associated with high relative humidity, wet weather, and cool spring temperatures (15-25 degrees C or 60-75 degrees F). punicae, of late, has become a major constraint in important pomegranate producing states of Maharashtra, Karnataka and Andhra Pradesh of India.

Bacterial blight caused by Xanthomonas axonopodis pv.punicae is a devastating disease causing huge economic losses in major pomegranate growing areas. Pomegranate bacterial blight appeared as an epidemic in Bangalore, Karnataka, India, causing 60-80% yield losses. Field evaluation over the seasons showed that bactrinashak, streptocycline or bacterimycin at 0.05% concentration in combination with COC 0.25% were equally effective in reducing the disease severity. Thus, this study has been undertaken to assess the effect of plant growth regulators (PGR s) and signal molecules on disease incidence of bacterial blight in addition to its impact on yield and productivity under field condition in disease endemic area. Presently, the disease occurs widely and outbreaks have been recorded in all major pomegranate-growing states including Maharashtra, Karnataka, and Andhra Pradesh. Pomegranate is one of the major cash fruit crops grown in India.Theblight disease ofpomegranate, when first reported, was known to be caused by Xanthomonas axonopodis pv. In the present investigation, a total of 209 genotypes including 105 exotic types from USDA, 66 wild types and 38 cultivated types from India were screened and categorized into fifteen clusters using cluster and principal component analysis. Xap produces smooth, circular, light yellow, glistening mucoid, butyrous and convex colonies with entire margins. The results indicated that before adopting the orchard integrated control management measures, the observed severity on the trees was up to 69%, and it was brought down to 10.15% in orchards where measures were adopted over three years.
