Abstract:
Pea (Pisum sativum) is one of the most important economic pulse crops which is infected by a serious disease is known as dry root rot which is caused by Rhizoctonia solani. Pea root rot complex, which is caused by several soil-borne fungi, is a significant yield-limiting factor for pea production around the world. Trichoderma species are well-known antagonists with high bio-control ability against phytopathogenic fungi that live in the soil. The Trichoderma isolates coiled around the Rhizoctonia solani hyphae, causing cell wall lysis, according to ultrastructural tests. Rather than antibiosis, parasitism accompanied by lysis was reported to be the mode of antagonism. Seed priming increased the efficacy of Trichoderma harzianum in controlling root rot diseases, with bio-priming seed treatments showing the highest rates of disease reduction. Seed coating with biocontrol agents was found to be more effective than fungicide seed treatment in reducing the occurrence of pea root rot disease.
