Abstract

Seed treatment is the use of seed as delivery system or deployment agent for different materials.Seed treatments offer economical and less polluting delivery system compared to other field application techniques, since only a relatively small amount of material is applied and is in immediate contact with target site. Seed coating with antagonistic microorganisms has been abundantly documented and there are several lines of experimental evidences to show that seed treatment with bacterial and fungal antagonistic are effective in protecting germinating embryos from pathogens. Reports clearly indicate the possibility of inducing Systemic acquired resistance(SAR) in host plant against pathogens by seed treatment with SAR inducers. Induction of resistance by seed treatment is of practical way to deliver benefits of SAR. This artificial manipulation of plants’ defense system provides a biologically, environmentally and commercially valuable,alternative to existing plant disease managing practices. The paper reports use of seed treatment ineffectively inducing SAR in otherwise susceptible pearl millet against Sclerospora graminicola(Sacc.) Schroet. The induced resistance is correlated to increase in growth parameters and increase in yield.
