Cellulase, Rhizoctonia solani Kühn., Trichoderma spp.
Some enzymes are secreted by biocontrol agents, which are increasingly preferred in agricultural control, and suppress the pathogen of diseases and decrease its growth and effects. Rhizoctonia solani Kühn., one of these pathogens, causes many losses in plants by causing many diseases such as root cancer, root rot and collapsing. One of the microorganisms that damage the cell walls of such phytopathogens and is therefore preferred as a biocontrol agent is Trichoderma spp. In this study, the reaction of Trichoderma spp. against R. solani and changes in the synthesis of endo-ß-1,4-glucanase enzyme were determined. Eleven different Trichoderma spp. and R. solani Kühn. isolates were used as materials. The enzyme activity results indicated that the cellulase enzyme activity of the R. solani samples increased significantly compared to the control group. TVD3 showed the highest enzyme activity while TH4 was the lowest. The most significant difference from the control group was in TVD3 isolate. These results suggested that Trichoderma spp. showed a biochemical response for defending the plant against R. solani. The results also support the effectiveness of Trichoderma spp. as a biological control agent and potential for the development of new eco-friendly commercial products.
