Abstract

Soil-borne fungal pathogens are a major constraint in tomato cultivation, often causing severe yield losses. This study aimed to optimise the dosage of Trichoderma-fortified compost (TFC) as an eco-friendly strategy for disease management and growth promotion. The antagonistic potential of Trichoderma harzianum isolate PABT-22 (TP-22) was validated in vitro, showing >90% inhibition against Fusarium oxysporum f. sp. lycopersici (Fo), Sclerotium rolfsii (Sr), and Rhizoctonia solani (Rs). The most effective isolate was incorporated into poultry manure compost and tested in field experiments with eight treatments, including five TFC dosages (100–500 g per 6 m² plot). All TFC treatments significantly improved plant growth compared with controls, with the greatest benefits recorded in T8 (500 g per plot ≈ 833 kg ha⁻¹). In T8 plots, disease incidence was reduced to 12.5% for Fusarium wilt and southern blight and 14.0% for Rhizoctonia root rot, compared with high incidence in pathogen-only controls. Yield increased by 27.3% (Fo), 29.6% (Sr), and 29.1% (Rs) under T8. These results confirm that a standardised dose of 500 g TFC per plot provides effective pathogen suppression and substantial yield, supporting its adoption as a low-cost, sustainable solution for tomato production.

Abstract

Southern blight, caused by Sclerotium rolfsii (Sr), is a major constraint to tomato production. We isolated 20 Sr strains and identified Sr-4 as the most virulent based on pathogenicity assays. In parallel, 102 Trichoderma harzianum (Th) isolates were screened, with four inhibiting Sr growth by ≥75% in dual culture; PABT-22 showed the highest inhibition. Pot and field experiments evaluated Trichoderma-fortified compost (TFC; 2.0–4.0 × 10⁸ spores mL⁻¹). TFC applied at 3.0 × 10⁸ spores mL⁻¹ (T7) reduced disease incidence to 8.4% and percent disease index (PDI) to 5.2%, providing 71.4% control compared with the pathogen control. T7 also achieved the highest yield (64.43 t ha⁻¹; +59.1%) and enhanced fruit quality, including increased β-carotene and lycopene content. These findings demonstrate that TFC, particularly PABT-22 at 3.0 × 10⁸ spores mL⁻¹, offers an effective, residue-free strategy for suppressing southern blight while improving yield and nutritional quality in tomato.
