University, Rohtak, Haryana (India) The aqueous extracts from twenty plants were screened by agar diffusion methods for their antibacterial activity against Rathyibacter tritici, a causal organism of tundu diseases of wheat. The Rathyibacter tritici was found most sensitive to the seed extracts of Acacia arabicae and seed extracts of Casuarinae equisetifolia. Some of the other plants showed the activity against the test bacteria in the following order Cuscuta reflexa > Anthocephalus cadamba> Azadirachta indica> Capparis decidua > Cassia fistula > Cannavis sativa > Brassicae jaunca> Clerodendron inerme. https://www.biotech-asia.org/vol5no1/antibacterial-activity-of-some-plant-extracts-against-rathyibacter-tritici/ Rathyibacter tritici; Antibacterial Activity; Plants-extracts; Phytochemicals
