Background: The studies were carried out to assess the effects of Trichioderma asperellum (ITCC 12187.25) (@ 1&times;108 CFUs/g) seed treatment on the population of plant parasitic nematodes of the green gram, black gram (kharif)&nbsp;and chickpea and field pea (rabi&nbsp;season) during the year 2023-24, in Jhansi and Jalaun districts. 
 
Methods: IPM study in pulse crops was compared in IPM-1 (T. asperellum seed treatment), IPM-2 (no treatment, KVK farms) and farmers practice (FP) across 11 villages in Jhansi/Jalaun districts during 2023-24 Rabi/Kharif seasons. 
 
Result: The IPM strategies were similar in IPM-1 and IPM-2 modules, except&nbsp;T. asperellum (ITCC 12187.25)&nbsp;seed treatment was applied in IPM-1 and IPM-2 was without the seed treatment. It was found that 100% reduction in&nbsp;Pratylenchus&nbsp;population in IPM-1 that ranged from 115.3&plusmn;12.6 to 177.0&plusmn;3.6/100 cc soil, 231.3&plusmn;55.2 to 369.0&plusmn;58.0/100 cc soil in IPM-2 and 244.0&plusmn;34.0 to 368.7&plusmn;49.3/100 cc soil in FP fields. However, the treatment indicated a significant (p&le;0.05) reduction in its population Hoplolaimus&nbsp;from 38.1% to 78.0%. Relatively, the&nbsp;Meloidogyne&nbsp;infestation was not found in the crops at Jhansi location. Whereas at Jalaun, the infestation varied from 4.3&plusmn;1.5 to 6.6&plusmn;1.8 galls/plant in IPM-1, 14.3&plusmn;3.1 to 17.0&plusmn;3.3 galls/plant in IPM-2 and 10.3&plusmn;3.5 to 20.0&plusmn;14.7 galls/plant in FP fields. Likewise, less infestation of Meloidogyne&nbsp;was also found in field pea IPM-1 that posed the nematode infestation could be suppressed using&nbsp;T. asperellum (ITCC 12187.25) as seed treatment. Consequently, greater net return could be achieved in IPM-1 than the IPM-2 and FP fields.
