Plant parasitic nematodes remain a major challenge to crop production that has hitherto received minimum research attention in Sub-Saharan Africa. The study of the sources of plant parasitic nematode on vegetable crops fertilized with organic manure at Presco Campus was conducted between the month of August to November, 2014 to determine the presence of plant parasitic nematode using centrifuge sedimentation methods and microscopy. The study revealed that out of the three vegetable crops examined, 30% death observed on watermelon (Citrullus lanatus) were as a result of the heavy load of the two nematodes of the Tylenchoid and Rotylenchulus where other vegetable crops assayed showed the presence of meloidogyne and Heterodera incognita, pratylenchus and Helicotylenchus at their various life cycle stages. Plant parasitic nematode can be controlled by adding agro-based fertilizer and not organic manures which can be seen to constitute the nematode pathogens responsible for plant damage and deaths.
