In protected bell pepper cultivation, the root knot nematode Meloidogyne incognita poses a severe threat in North and South India. Growers resort to costly synthetic nematicides, which not only inflate expenses but also exhibit phytotoxicity. To address this, a two-year experiment in Badoli village, Panipat, aimed to save a farmer from dismantling his polyhouse due to three years of losses. Soil solarization was performed for two consecutive years, resulting in an 80.19% and 75.74% reduction in M. incognita in the first and second years, respectively. In the first year, soil solarization with Trichoderma viridae and in the second year with Pochonia chlamydosporia led to the greatest reduction in M. incognita populations in soil and roots. Interestingly, soil solarization with Pochonia chlamydosporia increased the population of free-living nematodes (35.10% and 23.11% above control in the first and second years, respectively), enhanced plant growth (5.89% and 2.64% above control at harvest), and yielded significantly more (25.07 t/ha, a 46.35% increase over control). The farmer's profit surged to Rs. 5.79 lakhs, compared to a meager Rs. 1.0 lakh. Overall, soil solarization alone reduced root knot nematode populations, while FYM fortified with three biocontrol agents improved plant growth, fruit weight, and capsicum quality. The approach of using 25-micron polythene sheets for soil solarization in polyhouses during May-June, combined with FYM enriched with Pochonia chlamydosporia (TNAU-Pc001) at 2 Kg/tonne FYM and 1000 g per sq m before sowing and after six months, is recommended for effective M. incognita control.
