الملخص EN

The field survey was conducted for 48 greenhouses planted with eggplant in 26 towns and villages within Tartous Governorate, from the beginning of April until the end of June 2019.

Soil samples were taken from the greenhouses planted with eggplant, where a combined sample was collected from each protected house and mixed well to obtain a homogeneous sample, and eggplant root samples were collected from 10 greenhouses.

Laboratory analysis of soil samples was performed and the infectious densities of the second infectious larval (J2) larval nematodes of the Meloidogyne spp.

determined by the number of second phase larvae (J2) / 100 cm3, soil, to determine the type of nematode of roots that infect eggplant in the studied area.

The results showed wide spread of root nodes of the genus Meloidogyne spp.

In most studied greenhouses, the average number of second-stage larvae ranged from 3 - 82 larvae / 100 cm3 of soil, the results showed that the best varieties are those grafted onto a resistant origin Rihan on average 7.17 larvae / 100 cm3 of soil, then variety Karam 8.08 larvae / 100 cm3 of soil, the best pesticide is Nimakick on average 9.33 larvae / 100 cm3 of soil, then Oxamyl on average 23 larvae / 100 cm3 of soil, and the results also showed that the eggplant nematode type is Meloidogyne incognita.
