Host Status of Selected Crops to Meloidogyne chitwoodi.
Various crops were tested in greenhouse and field trials for their potential utility in the rotation sequence in the potato cropping system in Meloidogyne chitwoodi-infested soils of the Klamath Basin in northeastern California and southern Oregon, supporting the nematode population at its current level without substantial increase or decline.
“Resistance-breaking” nematodes identified in California tomatoes
Two field populations of Meloidogyne incognita that parasitize tomato plants containing the Mi gene are identified and this necessitates the use of planned crop rotation practices and the incorporation of other resistance genes into cultivated tomato.

Random amplified polymorphic DNA (RAPD) bands that distinguish Meloidogyne hapla and M. chitwoodi from each other, and from other root-knot nematode species, were identified using a series of random…
Alternatives to Methyl Bromide for Strawberry Runner Plant Production
For years, strawberry (Fragaria ×ananassa L.) runner plant nurseries have relied on methyl bromide (MB) fumigation of soil to produce healthy transplants. Methyl bromide, however, has been phased out…
Detection of the nematophagous fungus Hirsutella rhossiliensis in California sugarbeet fields
Evaluation of Hot Water Treatments for Management of Ditylenchus dipsaci and Fungi in Daffodil Bulbs.
Fungal genera commonly isolated from the bulbs in association with D. dipsaci were Penicillium sp.
Dose Response of Weed Seeds, Plant-Parasitic Nematodes, and Pathogens to Twelve Rates of Metam Sodium in a California Soil.
The results indicate that metam-Na can provide effective pest and disease control at maximum label rate for the commercial formulation, but there was a reduction in efficacy at low temperature.
Plant Parasitic Nematodes in California Agriculture
In this chapter, a developmental account of Nematode problems associated with major crops, nematode biology and regional distribution, and past to present management practices including sustainable strategies are discussed for certain main, economically important plant parasitic nematodes species.
