Agriculturally-polluted Irrigation Water as a Source of Plant-Parasitic Nematode Infestation

L. R. Faulkner, W. J. Bolander


Water from a major irrigation canal and water from a deep well was used to irrigate plants growing in methyl bromide fumigated screenhouse ground beds. Nematode populations in these beds were compared during three seasons of continuous cropping to alfalfa, bean, eggplant, mint, sugarbeet, or wheat. Beds irrigated with canal water became heavily infested with a variety of plant parasitic nematodes while those receiving well water did not. Key Words: Ditylenchus dipsaci, Paratylenchus, Meloidogyne, Pratylenchus, Tylenchorhynchus, Alfalfa, Bean, Eggplant, Mint, Sugarbeet, Wheat.
