Silicon is largely available in earth crust in second only to oxygen. Few organism and accumulate silicon plants take up various quantities of silicon in certain species. The silica accumulates were found in monocotyledonous plant families. Rice accumulates about 4-20% of silica in paddy straw as well as every part of rice plant. Mineralization of silicate in soil take place by numerous bacteria particularly Bacillus muciloginosus. Silicate solubilizing bacteria was isolated from twenty rhizosphere soil of rice in various locations of Cuddalore district. All the twenty isolate were screened for the ability of silicate solubilization and antagonistic activity against pyricularia oryzae. The isolates viz., SSB-8, SSB-11, and SSB-17 was recorded a maximum response to silicate solubilization and biocontrol characteristics. The effect of different formulations of silicate solubilizing bacterial strains, natural and artificial biofloc of SSB cells on incidence of pyricularia oryzae was studied. Among the different formulations of silicate solubilizing bacteria reduced the incidence of pyricularia oryzae to a higher level when compared to the vegetative cells forms of the same.

Silicate solubilizing, pyricularia oryzae, monocotyledonous, antagonistic activity, etc.
