In vitro nutritional management of bacterial blight of Pomegranate

Pomegranate belonging to family Punicaceae is one of the consumers' preferable and favorite dollar earning table fruit of tropical and subtropical regions. It has high nutritional as well as medicinal values. It suffers from various diseases, amongst them bacterial blight caused by Xanthomonas axonopodis pv. punicae is an economically important disease of pomegranate in Maharashtra. The disease affects all the above ground plant parts including flowers, leaves, twigs, stem buds and fruits but it is more destructive when fruits are infected. The bacterium has developed resistance to commonly used fungicides and antibiotics. Therefore, a study was carried out to find out eco-friendly solution to mitigate the disease with the help or application of micronutrients and humic acid. In this study of curative effect of micronutrient spray and humic acid drench, injury was made to five (5) leaves with sterilized needle in every concentration of all micronutrients and humic acid before spraying of bacterial blight suspension and observed the incidence of the disease. Almost all injured leaves were infected with the disease and no control of disease was observed in both the treatments.
