Mycorrhizal symbiosis and application of vitamin B3-treated Trichoderma Harzianum HE24 additively trigger immunity responses in faba bean plants against Rhizoctonia root rot and promote the plant growth and yield

Researchers found that combining a beneficial fungus called Trichoderma harzianum with vitamin B3 and mycorrhizal fungi can effectively protect faba bean plants from root rot caused by Rhizoctonia solani. This combined treatment boosted the plant’s natural defense systems and significantly improved plant growth and seed production. The approach offers an environmentally friendly alternative to chemical fungicides for controlling this destructive plant disease.
