Symptoms Caused by Phytonematodes and Disease Diagnosis,nemies” of crops. They can cause significant plant damage ranging from negligible injury to the total destruction of plant material. 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

Crop Loss Assessment,ting, the susceptibility and tolerance of the host, and a range of environmental factors (Trudgill and Phillips 1997). 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

Identifying a nematode problem comprises various steps, viz., drawing of suitable samples of soil and plant parts from the infested field, processing the samples to extract nematodes, separating and identifying specific parasitic species of the phytonematode based on morphologic
