Larvicidal activity of plant oil of Rosmarinus officinalis against the selected mosquitoes larvae

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.
