Bio-control management of foot and root rot disease of lentil as impacted by different formulations of Trichoderma product

Foot and root rot disease, caused by Fusarium oxysporum and Sclerotium rolfsii, is one of the most devastating lentil diseases, resulting in decreased yield. A study was done to assess the efficacy of several Trichoderma formulated products in treating lentil foot and root rot disease as a biocontrol agent. The study used a Randomized Complete Block Design (RCBD), with seven treatments, viz., T1 = Control, T2 = Decoprima, T3 = Lycomax, T4 = Dynamic, T5 = Tricost, T6 = Provax 200 WP, and T7 = Trichoderma. All treatments were applied as seed treatments and sprays to the plant's basal region (root zone). Data were obtained on several days following the sowing dates. The findings showed that the numerous treatments used had a considerable impact on yield, contributing features, and growth indices. T3 (Lycomax) showed promising results in reducing lentil overcontrol disease among foot and root infection treatments. The disease incidence was lowest in T3 (15.23%) and highest (31.25%) in the control group. T3 also exhibited the highest plant height, branches/plant, nodules/plant, pods/plant, root length/plant, and yield compared to the control. Given the performance of the biocontrol agents assessed in the study, Lycomax might be recommended for producers to treat their seed and use basal spraying of this biocontrol agent to manage foot and root rot of lentil.
