First report of rice root-knot nematode (Meloidogyne graminicola) infecting wild jute (Corchorus aestuans)

A wild species of jute, Corchorus aestuans (family: Tiliaceae), was found to be infected root-knot nematode, Meloidogyne graminicola. The pathogenicity M. graminicola on C. (local cultivar) under pot conditions showed that could infect, reproduce, and incite profuse root galling in aestuans. initial inoculum 10-second stage juveniles per 1000 cm3 soil displayed the highest reproduction factor (Pf/Pi, RF = 145). Our findings demonstrated as a good host graminicola, its infection roots exhibits typical terminal gall with distinct egg mass visible from outside. To our knowledge, this is first report West Bengal, India.
