Biochemical mechanism of native fungal bioagents in the management of root-knot nematode Meloidogyne incognita on tomato

Analysis of defense-related enzymatic activities of the fungal bioagents viz., Trichoderma viride, T. harzianum, Pochonia chlamydosporia and Purpureocillium lilacinum against root-knot nematode Meloidogyne incognita on Tomato were carried out and revealed that all the tested fungal bioagents have the ability to induce defense-related enzymatic activity against M. incognita which resulted in the increase in the plant growth parameters like shoot height, shoot weight, root length, root weight after 15, 30 and 45 days after inoculation (DAI) and decrease in the nematode multiplication on the tomato and in the soil as compared to the untreated control after 30 and 45 DAI.
