Biocontrol potential of phylloplane bacterial antagonist against chilli anthracnose and powdery mildew disease

Ahila devi;R. Priyanga and V. Prakasam

Abstract

Studies on the nature of phylloplane microflora of chilli yielded two new isolates each of Pseudomonas fluorescens (CPf1 and CPf2), Bacillu subtilis (CBs1 and CBs2), and Streptomyces roschi.(CSr1 and CSr2).The efficacy of the newly identified isolates of P. fluorescens, B. subtilis and S. roschi was very less when compared to the existing strain Pf1 of P. fluorescens, Bs1 strain of B. subtilis and Sr1 strain of S. roschi . Based on the studies on efficacy and antagonism, Pf1 of P. fluorescens and Bs1 strain of B. subtilis were selected for further studies.
