Application of mixture of microbial strains performing different function such as biodegradation, biocontrol etc. for eco-friendly sustainable agriculture would more closely mimic the natural situation and might broaden the spectrum of activity and enhance the efficacy and reliability of mankind on microorganisms. In present investigation compatibility of biocontrol bacterial strains viz. Providensia vermicola AAU PR1 (KJ161325), Pseudomonas putida AAU PR2 (KJ161326) and P.fluorescens AAU PR3 (KJ161327) with biocontrol fungi viz. Trichoderma harizianum, T.viride, Paecilomyces lilacinus, Verticilium licanii and biodegrader fungi viz. Chaetomium globosum, Pleurotus ostreatus, Emericella nidulans, A.terreus, A.wentii was evaluated. All the test fungi were found compatible with bacterial biocontrol strains. However presence of bacterial strain restricted the growth of biocontrol fungi viz. T.harizianum, T.viride, P.lilacinus and V.licanii initially but soon after the fungi has overcome the hurdle and get momentum and found to grow luxuriously on agar plate showing compatible nature of both the partners.
