Abstract:
The role of extracellular enzymes by Trichoderma MM35 for control of soybean rootrot pathogens(Fusarium oxysporum , Rhizoctonia solani) was assessed invitro and in vivo. De-tective levels of hydrolytic extracellular enzymes were recorded by Trichoderma MM35 usingdried F. oxysporum mycelium as C-source in vitro or fresh F. oxysporum mycelium or fresh R.solani mycelium in vivo was found that there were significant increases in chitinase activities byTrichoderma MM35 in soil with inoculation of F. oxysporum. Soil infested with TrichodermaMM35 had significantly elevated chitinase and β - 1, 3- glucanase activities in presence of R. so-lani as compared to R. solani control.
