Production of biocontrol determinants by antagonistic bacteria in presence and absence of P.oryzae.
T1 = P.oryzae, T2 = Bacillus sp KFP-5+P.oryzae, T3 = Bacillus sp KFP-7+P.oryzae, T4 = Bacillus sp KFP- 17+P.oryzae, T5 = Bacillus sp KFP-5, T6 = Bacillus sp KFP-7.T7 = KFP- Bacillus sp 17. Values are mean of three replicates Bars represent the standard error of means. All treatments are significantly different from each other at P<0.001.

SOD contents in leaves and roots of different rice varieties grown hydroponicaly (left panel a, b, c and pot/soil experiment (right panel d, e,f).
T1 = P.oryzae, T2 = Fungicide +P.oryzae, T3 = Bacillus sp KFP-5+ P.oryzae, T4- Bacillus sp KFP-7+ P.oryzae T5 = Bacillus sp KFP-17+ P.oryzae T6 = untreated. Values are means of three replicates and vertical bars represent the standard error. All treatments are significantly different from each other at P<0.001.
