Trichoderma harzianum (LS: TH38) induced systemic resistance in rice (Oryza sativa) by enhancing various components involved in pathogen suppression. Different physiological processes that are related with growth promotion were positively induced by T. harzianum even under infection by sheath blight. Thus reduction in disease severity and nullifying its negative impact on the plant growth implicates the importance of T. harzianum as a biocontrol agent. However, comparative study with systemic fungicide bavistin showed that the efficacy level of T. harzianum against sheath blight disease needed further improvement in order to replace chemical fungicides.
