Root rot disease induced by Fusarium solani f.sp. pisi has been observed as an important disease problem on pea (Pisum sativum L.) at Jobner (Jaipur) and nearby areas. In vitro efficacy test of various systemic and non systemic fungicides against F. solani f. sp. pisi by using following poisoned food technique. Bavistin + Thiram and Bavistin were found to be most effective with complete inhibition of mycelium growth of the fungus at 300 ppm concentrations followed by Topsin –M + Thiram, Topsin –M, Thiram, Indofil M-45 and Blitox-50. In a pot house assay, Bavistin + Thiram was found to be most effective with minimum pre and post –emergence mortality of pea seeds against F. solani f.sp. pisi. It was followed by Bavistin and Topsin M+Thiram. Biocontrol agent, Trichoderma harzianum was found most effective against the fungus in vitro and in vivo (Pot condition). Maximum reduction in root rot incidence was observed when seeds were treated with T. harzianum (bioderma).
