3012 - General Soil Sample
Root galls induced by M. artiellia are very small and often are covered by large egg masses that represent the only visible signs of the nematode infection.
Root-knot nematodes (RKNs) symptoms are similar to those caused by nutrient or water deficiency, including stunting, wilting, and chlorosis of leaves. Small root galls and lateral proliferation of roots is also observed with most species.
In wheat, spikes are sparse and reduced in size.
1. Assessment of root galls will indicate a possible root knot nematode infection.
2. Morphological: The length of at least 20 second-stage juveniles, the head and stylet morphology of males, and the nature perineal patterns of females from samples.
Meloidogyne artiellia can be confused with other root-knot nematodes, including M. acrita, M. arenaria, M. christiei, M. cruciana, M. megatyla, M. hapla, M. incognita, M. graminis, M. javanica, M. querciana, and M. thamesi.
In Progress / Literature-based Diagnostics:
Molecular: RFLP profiles of the ITS region of rDNA, RAPD fragments, 18SrDNA sequences, satellite DNA probes and species specific primers can distinguish from other species (DiGiorgi et al., 1991; 1994; 2002).
Damages cereals, leguminous, and cruciferous crops in Europe and Middle East. This nematode can be introduced with contaminated machinery, soil debris, and rooted propagative plant material.
