When specimens are placed in the lateral position, the distance between the dorsal esophageal gland orifice to the stylet base can be used to distinguish between species of Meloidogyne (Cunha et al. 2018).

This analysis is based on the mobility of the enzymes in the extracted protein, which is diagnostic of different species of Meloidogyne (Cunha et al. 2018).

When DAPG is produced, it induces resistance in tomatoes against the root knot nematode, Meloidogyne javanica (Escobar et al. 2015).

The specific chemical control utilized is nematicide toxins, including Aldicarb, Enzon, Oxamyl, and Cadusafos (Rugby).

A cultural practice used to control Meloidogyne javanica is crop rotation with non-host species or resistant cultivars.

Rotation crops such as marigolds, perennial grasses, and bermudagrass have been successful in suppressing the disease caused by M. Javanica (Escobar et al. 2015).

This management style is effective when the nematodes are host-specific, as rotating with a non-host crop eliminates the pathogen's ability to infect.

In addition, when M. javanica infects the root, the female finds its permanent feeding site where it is surrounded by 3–4 large giant cells.

The nematode induces the plant to form large multinucleate giant cells adjacent to the stele tissue, modifying the structure of the vascular cylinder.

The roots infested with the pathogen contain 5–6 giant cells with hypertrophic nuclei causing the interruption of vascular bundles in the stellar area (Kheir 1979).
