Journal ArticleDOI
Phytophthora ramorum as the Cause of Extensive Mortality of Quercus spp. and Lithocarpus densiflorus in California.
TL;DR: A new canker disease, commonly known as sudden oak death, of Lithocarpus densiflorus, Quercus agrifolia, Q. kelloggii, and Q. shrevei in California is shown to be caused by Phytophthora ramorum, a recently described species that was known only from Germany and the Netherlands on Rhododendron spp.
Journal ArticleDOI
Winter cover crops in a vegetable cropping system: Impacts on nitrate leaching, soil water, crop yield, pests and management costs
TL;DR: In this article, the effect of altering surface soil dynamics, using a winter cover crop rotation, on biotic and abiotic characteristics of the soil profile was investigated, emphasizing nitrate (NO3-N) leaching during winter, and N availability during the subsequent broccoli crop.
Journal ArticleDOI
Development of an assay for rapid detection and quantification of Verticillium dahliae in soil.
TL;DR: A multiplexed TaqMan real-time polymerase chain reaction (PCR) assay based on the ribosomal DNA (rDNA) intergenic spacer (IGS) was developed for Verticillium dahliae to provide a faster means for estimating pathogen populations in the soil.
Journal ArticleDOI
Effects of Crop Rotation and Irrigation on Verticillium dahliae Microsclerotia in Soil and Wilt in Cauliflower.
TL;DR: Rotating broccoli with cauliflower and incorporating broccoli residues into the soils is a novel means of managing Verticillium wilt on cauliflowerand perhaps on other susceptible crops.
Journal ArticleDOI
Evaluation of Broccoli Residue Incorporation into Field Soil for Verticillium Wilt Control in Cauliflower
TL;DR: It is suggested that broccoli residues reduce V. dahliae microsclerotia in soil and wilt of cauliflower as much as or more than chloropicrin and metham sodium, and that rotation with broccoli may be a feasible approach to manage Verticillium wilt in cauliflower and other susceptible crops.
