CONTROL OF RICE BLIGHT PATHOGEN XANTHOMONAS ORYZAE THROUGH HERBAL PLANT EXTRACT
AbstractRice is the most widely cultivated food crop over world, whose production is effected by many diseases like as fungal, bacterial and viral. Bacterial blight disease of rice caused by Xanthomonas oryzae. Chemical substance like Bordeaux mixture, copper and mercurial compounds have been used. Extensive use of these chemical causes harmful impacts on human and environment. For reducing problems associated to chemical substance, herbal plant like Aloe Vera gel and Cassia occidentals seed extract can be used for controlling disease cause through Xanthomonas oryzae (Xoo) in rice crop. The result of this study indicated that the Aloe Vera gel and seed extract of Cassia occidentalisplants contain some major bioactive compounds that inhibits the growth of the Xanthomonas oryzae and provides zone of inhibition, as Aloe Vera at 100% concentration provide diameter 14mm zone of inhibition in seed extract of Cassia occidentalis at 30mg/ml, 60mg/ml and 120mg/ml provide 5 mm, 9mm and 12mm diameter zone of inhibition respectively as It can be very important, for disease treatment in plants.
