Effect of Pseudomonas exopolysaccharides (an elicitor) on the enhancement of plant growth and biocontrol against Pyricularia oryzae of rice var. (ADT-36)


P Manikandan, S Kalaiarasu

A study on the incidence of blast disease in rice using different concentrations of purified exopolysaccharides (100, 200, and 300 ppm) when compared to other concentrations, the use of the same at a concentration of 200 ppm effectively controlled the disease incidence to a greater extent. The results also showed that pseudomonas exopolysaccharides have a dual effect on host plant growth enhancement and Pyricularia oryzae biocontrol, whereas the use of Induced Systemic Resistance inducing chemicals was limited to a reduction in blast disease incidence. Interestingly, pseudomonas exopolysaccharides at 200 ppm were found to be effective in controlling blast disease in upland rice.
