The severity of plant injury resulting from nematode activity depends on several factors such as the combination of plant and nematode species and prevailing environme

Because of this, available models only estimate yield losses as proportions of the nematode-free yield. Estimating threshold levels further involves various economic calculations. C

Genetics of Nematode Parasitism, to overcome the resistance of the host plant (Sidhu and Webster 1981). Most notably, all phytonematodes are equipped with a stylet to pierce cell walls and allow solute exchange between plant and parasite. Furthermore, plant-parasitic nematodes have well-developed secretory gland cells associated w
