Pathogenicity of root-knot nematode, Meloidogyne incognita on pea

Pathogenicity of Meloidogyne incognita on pea variety Boneville was studied with four inoculum levels viz. 10, 100, 1000 and 10,000 larvae of M. incognita per 500 g soil alongwith check. Significant plant growth reduction was found with an initial inoculum of 1000 larvae of M. incognita per plant per 500 g of soil. Maximum number of galls and egg masses were found at 1000 larvae per 500 g of soil. The reproductive rate of nematode was maximum at the lowest inoculum density and minimum at the highest inoculum density.
