Foot and root rot is one of the most serious yield-reducing diseases in peas. Fusarium oxysporum andSclerotium rolfsii are primarily responsible for the development of pea foot and root rot diseases.This study was conducted to test the fungicide of theTrichoderma group for the control of foot and root rot in peas. Bio-fungicidal treatments of the Trichoderma group – Decoprima (T2), Lycomax (T3), Dynamic (T4), Tricost (T5), Provax 200 (T6), and Trichoderma (T7)– were used to compare results with untreated control plots. Lycomax (T3) performed well in suppressing pea foot and root rot disease, as well as other growth traits across different days after sowing (DAS). Lycomax (T3) gave the highest yield (39.81 g/plot) at 92 DAS compared to other treatments and untreated plots (11.67 g/plot). Although the chemical treatment Provax 200 (T6) controlled pea foot and root rot disease and yielded 33.76 g/plot, it is not eco-friendly. Lycomax (T3) achieved the greatest results at 75 DAS in all traits, including surviving seedlings (64.67/plot), infected plants (4/plot), plant height (67.33 cm/plot), and root branches per plant (33.33/plot). The plot treated with Lycomax (T3) had the greatest root length (28.33 cm/plot), root nodules (30.33/plant/plot), and branches (33.33/plant/plot) at 82 days after sowing. The flowers (76/plot) and pods (12.33/plot) peaked at 65 and 75 DAS, respectively. The current study has demonstrated that Lycomax (generic name: Trichoderma) is the best bio-fungicide to treat pea foot and root rot disease in an eco-friendly manner and boost production by improving plant health.
