Evaluation of Trichoderma harzianum as a potential bio-control option for fungal root disease of Seabuckthorn
AbstractBiocontrol involves harnessing disease suppressive micro-organisms to improve plant health. Owing to the shortage of available fungicides for economic management of soil borne diseases, alternative techniques such as biological control are increasingly being sought for disease management. The present work was carried out to study the potential of Trichoderma harzianum isolate screened from the rhizospheric soil of seabuckthorn growing areas in Uttarakhand. Antagonistic activity of isolate was observed against Fusarium oxysporum causing damping off disease in seabuckthorn. Under in vitro conditions Trichoderma harzianum significantly reduced the growth of pathogenic Fusarium oxysporum.
