The problems associated with nematode diseases of plants can be visualized as one part of a system consisting usually of three components: nematodes, plants and the linking medium, most frequently soil.
Also in this issue:Plant nematology in California: State's: Crop losses led to first department for research in plant nematology to be established by experiment stations
Nematodes in plant quarantine: Detection of plant parasitic nematode infestations difficult because of complexity of possible causes of visible symptoms
Nematode structure and life: Wide range of life habits requires combination of characters for identification of parasites classified among nematodes
Field and vegetable crops: Wide ranges of crops and climatic conditions in California necessitate development of several diverse control programs
Nematodes in grape production: Distribution records show multiple infestations of two or more species of nematodes to be in most of California's vineyards
Citrus and avocado nematodes: Spread by nursery stock, by contaminated implements, and by water from irrigation canals that may drain infested land
Deciduous fruit and nut trees: Root-knot nematode on peach and root-lesion nematode on walnut cause serious problems for California orchardists
Nematodes on ornamentals: Root-knot, root-lesion, and more specialized or exotic forms may cause acute injuries in nursery, greenhouse, and garden
Natural enemies of nematodes: Studies of complex soil environment aimed at favoring fungi and other organisms that limit plant nematode populations
Chemical control of nematodes: Effective nematocides relatively few in number but available in several forms for field use on perennial and annual crops
