Impact of certain medicinal and aromatic plant products on Meloidogyne incognita infecting eggplant under greenhouse conditions [electronic resource].

Includes references.

The impact of nine medicinal and aromatic plant products as ground-oilseeds i.e. fenugreek, arugula, coriander, celery and dill; and dried leaf powders i.e. peppermint rosella, periwinkle and throne apple separately in comparison with oxamyl on M. incognita infecting eggplant cv. Black Long under greenhouse conditions, indicated that all tested materials obviously improved plant growth parameters of eggplant plants and significantly diminished nematode development and reproduction. Fenugreek as ground-oil-seeds application represented the maximum percentage increase values of plant length (54.3%), total plant fresh weight (177%), shoot dry weight (142.7%) and number of leavesl plant (117.4%) whereas ground-oil-seeds of dill gave the least percentage increase values in this respect. However, peppermint as powder also represented the maximum increase values of ameliorating plant length (53.6%) , total plant fresh weight (158.4%), shoot dry weight (138.8%) and number of leaves 1 plant (108.7%), respectively, followed by that of rosella and throne apple whereas periwinkle showed the least values of the same plant growth criteria. Oxamyl ranked first and surpassed other tested applications in percentage increase values of the same plant growth criteria, respectively, and in diminishing nematode criteria with the lowest reproduction factor (RF) value of 0.37 vs 4.6 for nematode alone. Fenugreek treatment overwhelmed other tested ground-oilseeds in suppressing nematode population density (81.1%), root galling (92.8%) and eggmasses number (92.0%), followed by arugula application.
