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 KlamathExpand
“Resistance-breaking” nematodes identified in California tomatoes
Resistance to root-knot nematodes in tomato is conferred by the gene Mi. We have identified two field populations of Meloidogyne incognita that parasitize tomato plants containing the Mi gene. ThisExpand
Sensitive PCR Detection of Meloidogyne arenaria, M. incognita, and M. javanica Extracted from Soil.
We have developed a simple PCR assay protocol for detection of the root-knot nematode (RKN) species Meloidogyne arenaria, M. incognita, and M. javanica extracted from soil. Nematodes are extractedExpand
Evaluation of Hot Water Treatments for Management of Ditylenchus dipsaci and Fungi in Daffodil Bulbs.
Treatment of daffodil (Narcissus pseudonarcissus) bulbs in a 0.37% formaldehyde water solution at 44 C for 240 minutes is a standard practice in California for management of the stem and bulbExpand
A PCR Assay to Identify and Distinguish Single Juveniles of Meloidogyne hapla and M. chitwoodi.
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 randomExpand
Detection of the nematophagous fungus Hirsutella rhossiliensis in California sugarbeet fields
Abstract The nematophagous fungus, Hirsutella rhossiliensis, was detected in 10 of 21 sugarbeet fields in California. Fewer than four parasitized nematodes per 100 cm3 soil were found in any field,Expand
Dose Response of Weed Seeds, Plant-Parasitic Nematodes, and Pathogens to Twelve Rates of Metam Sodium in a California Soil.
Metam sodium (sodium N-methyl dithiocarbamate, metam-Na) is widely used in agricultural and floricultural production for controlling soilborne plant pathogens, parasitic nematodes, and weeds. ItExpand
Longevity and food consumption of microwave-treated (2.45 GHz CW) honeybees in the laboratory.
Adult honeybees, confined singly or in small clusters, were exposed for 0.5, 6, and 24 hours to 2.45-GHz continuous wave microwave radiation at power densities of 3, 6, 12, 25, and 50 mW/cm2.Expand
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 outExpand
Successful establishment and subsequent recycling of Romanomermis culicivorax (Mermithidae: Nematoda) in a California rice field following postparasite application.
An early season application of postparasites of the mosquito-parasitic nematode Romanomermis culicivorax demonstrated that the nematodes could mature to adults, mate, and lay eggs in the rice fieldExpand
