| Total of 402 bacterial isolates for antagonistic screening against Fusarium fujikuroi, the causal agent of rice bakanae disease were isolated from rhizosphere soil of rice . Out of them, 23 isolates showed antagonistic activity against Fusarium fujikuroi by dual culture method test. In greenhouse experiment for the control rice bakanae, the most effective antagonistic bacteria were BAK 20, BAK 48 and BAK 109 which had the disease incidence 23.57 25.46 and 37.05 %, respectively whereas the control was 72.31%. Efficiency of powder formulation of antagonistic bacteria to control rice bakanae disease was studied in field experiment at Phatthalung Rice Research Center, in wet and dry seasons 2013. The experiments were designed as RCB (Randomized Complete... |
