Abstract

Coriander (Coriandrum sativum L.) is well known seed spice used in India. It is affected by powdery mildew caused by Erysiphe polygoni DC which is most destructive pathogen. PGPR is gaining importance in present era due to organic crop production and its concern on mankind and ecosystem. A total 25 fluorescent Pseudomonads (PGPRs) isolates were collected from Gokak, Khanapur and Hukkeri taluk of Belagavi district (Karnataka, India). Further, identification of fluorescent Pseudomonads was done by cultural, morphological and biochemical characterization. Antagonistic activity of 25 fluorescent Pseudomonads were assessed against powdery mildew conidial inhibition under in vitro condition. Among isolate, FP-11 recorded highest spore inhibition (43.28 %) followed by FP-8 (40.78 %).
