From this study we could conclude that, resistant cultivars are the single effective solution to management of root-knot nematode population avoid crop losses. Also, it is essential use in situations where nematodes present and when control advantageous yields. However, reported moderately cultivars, viz. Gujarat Rajmash, Amber (IPR 96-4) HUR15 belong secondary gene pool with cross-compatibilit...

Root-knot nematodes, particularly Meloidogynejavanica (Treub.) Chitwood, 1949 and M. incognita (Kofoid and White) Chitwood, 1949, are among the most important pathogens of carrots (Daucus carota L.) in Brazil. They damage tap roots by galling, digitation, and constriction, resulting in lower market value (3). Even low soil densities of root-knot nematodes have been reported to reduce marketable...

Root-knot nematodes are globally the most aggressive and damaging plant-parasitic nematodes. Chemical nematicides have so far constituted the most efficient control measures against these agricultural pests. Because of their toxicity for the environment and danger for human health, these nematicides have now been banned from use. Consequently, new and more specific control means, safe for the e...

Sweet potato is infested by root-knot and reinform nematodes. Root-knot nematode infestation in sweet potato is studied in detail. A number of resistant varieties are released in sweet potato from USA, Japan and China. A number of germplasm accessions and cultivars/ varieties were found resistant to the nematodes in Peru. Studies carried out by the authors indicated that sweet potato germplasm ...

Mining the secretome of root-knot nematodes for cell wall modifying proteins.

The southern root-knot nematode, Meloidogyne incognita, is the most damaging pathogen of cotton in the USA. Host-plant resistance to root-knot nematodes is an effective means of reducing crop losses and reducing nematode population levels in a field. Resistance to plantparasitic nematodes refers to the suppressive effect of the plant on the nematode’s ability to reproduce; tolerance describes t...

When nematodes invade and subsequently migrate within plant roots, they generate cell wall fragments (in the form of oligogalacturonides; OGs) that can act as damage-associated molecular patterns and activate host defence responses. However, the molecular mechanisms mediating damage responses in plant-nematode interactions remain unexplored. Here, we characterized the role of a group of cell wa...

Root-knot nematodes (Meloidogyne spp.) are considered as one of the main limiting factors in crop production systems. Currently, several eco-friendly root-knot control technologies have been developed, which is biofumigants. The purpose this study was to determine effectiveness biofumigants from Brassicaceae and Non-Brassicaceae nematodes. conducted using a one-factor Completely Randomized Desi...

Root-knot nematodes (Meloidogyne spp.) are sedentary endoparasites with a broad host range which includes economically important crop species. Cowpea (Vigna unguiculata L. Walp) is an important food and fodder legume grown in many regions where root-knot nematodes are a major problem in production fields. Several sources of resistance to root-knot nematode have been identified in cowpea, includ...
