Overview

Field trial demonstrates Purpureocillium lilacinum reduces Meloidogyne incognita damage in tomato and eggplant, highlighting an eco-friendly biocontrol option.

Key Points

  • To evaluate the efficacy of soil-applied egg-parasitic fungi enriched with farmyard manure against the root-knot nematode Meloidogyne incognita in tomato and eggplant crops.
  • Conducted a two-year field trial (Rabi 2024–2025) in Assam, India under the AICRP on Nematodes in Agriculture.
  • Evaluated soil applications of Purpureocillium lilacinum and Pochonia chlamydosporia (each at 2.5 kg/ha) enriched with farmyard manure (FYM, 2.5 t/ha) alongside a carbofuran 3G comparison.
  • P. lilacinum + FYM suppressed M. incognita populations in tomato (root population: 43/10 g roots; soil J2s: 149/200 cc; egg masses: 51.1/root system) and eggplant (root population: 82.5/10 g roots; soil J2s: 163/200 cc; egg masses: 50.4/root system).
  • P. lilacinum + FYM reduced the root-knot index to 2.6 in both crops, producing yields of 20.8 t/ha in tomato and 18.7 t/ha in eggplant, whereas P. chlamydosporia + FYM offered moderate suppression inferior to carbofuran 3G.
