Efficacy of Trichoderma spp. against Common Fungal Pathogens

Nowadays, organic food production demands more environmental friendly control of plant diseases. Biocontrol based on Trichoderma spp. usage is a promising due to Trichoderma is aggressive to broad range of phytopathogenic fungi. Given that, the aim of this study was to test in vitro antagonistic ability of ten native Serbian Trichoderma strains to ten common fungal pathogens. Study confirmed that Trichoderma spp. inhibits radial growth of Ascochyta pinodella (76.9%), A. pinodes (60.0%), A. pisi (68.5%), Fusarium graminearum (71.1%), F. proliferatum (63.9%), F. verticillioides (62.6%), F. oxysporum (63.9%), Macrophomina phaseolina (63.8%), and Pyrenophora teres (83.9%). These are first reports of Trichoderma spp. in vitro efficacy against A. pisi, A. pinodes, A. pinodella and P. teres. The lowest inhibitory effect was registered in dual cultures with Sclerotinia sclerotiorum - 52.2%
