Abstract
Okra [Abelmoschus esculentus L., Moench] a native of South-Africa and commonly known as ‘Bhindi’ is an annual malvaceous vegetable crop, especially grown in tropical and subtropical climates. It is also called “perfect villager’s vegetable”. Root-knot nematodes are considered among the top five major plant pathogens and the first among the ten most important genera of plant parasitic nematodes in the world. Amongst nematodes, root-knot nematode (Meloidogyne incognita and Meloidogyne javanica) causes severe damage to okra. Trichoderma viride, Pseudomonas fluorescene and Rhizobium were tested under field conditions during Rabi 2020-2021 for their efficacy against the Root knot nematode and growth & nematode population.
