Abstract:: Nematodes are roundworms with complex organ systems. They occur worldwide in all environments. Most species benefit agriculture by contributing to decomposition of organic matter and are important members of the food chain. Some species are parasitic to plants or animals. More than 2,000 of the 20,000 identified nematode species are...

Abstract:: Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. This publication provides a description and information on biology,...

Creator:: Howland, Amanda D.
Abstract:: A major constraint to the production of self-rooted wine grapes (Vitis vinifera) in eastern Washington is plant-parasitic nematodes. Plant-parasitic nematodes can impact grape productivity by limiting water and nutrient uptake, educing physiological changes, and extracting plant nutrients from roots, thereby reducing root biomass, plant vigor, and yield. The most commonly...
