A mesoscale model is used to examine the dynamics of northwest flow over the Santa Barbara Channel region.
Three cases are considered, each characterized by typical summertime synoptic conditions, but with differences
in pressure gradient strength and marine boundary layer depth (MBL). The first case examines a relatively deep
MBL...
Pesticides, including insecticides, acaricides, fungicides, bactericides, and herbicides are essential for maintaining healthy grape crops with reliable
yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose...
Month-long simulations using the fifth-generation Pennsylvania State University–National Center for Atmospheric
Research Mesoscale Model (MM5) with a horizontal resolution of 9 km have been used to investigate
perturbations of topographically forced wind stress and wind stress curl during upwelling-favorable winds along
the California and Baja California coasts during June 1999....
Grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Homoptera: Phylloxeridae), is an aphidlike insect that feeds aggressively on grape roots. Phylloxera is native to the eastern and southeastern United States, where native American grape species coevolved with the insect.
The aim of the study was to determine the effect of modified atmosphere (MA) packages on the external quality of organically grown lowbush blueberry and half-highbush blueberry ('Northblue') and the nutritional value of the fruits. Fruits were divided into plastic punnets and stored as follows: regular atmosphere (RA), punnets without...
Pesticides—including insecticides, acaricides, fungicides, and bactericides are essential for maintaining healthy crops with reliable yields and quality. In many instances, pesticides have become less effective as target organisms have developed resistance. The first record of resistance dates to 1897, when orchardists began having problems controlling San Jose scale (Quadraspidiotus perniciosus...
This guide is developed for use by managers of commercial vineyards in Oregon. It provides recommendations for chemicals, formulations and usage rates of products that are intended to prevent, manage and control vineyard diseases, insects, mites and weeds. When considering a pesticide, evaluate its efficacy and its impact on beneficial...
Learn the most effective techniques for controlling insects, weeds and disease on wine grapes in Oregon. This comprehensive publication for growers covers strategies for controlling powdery mildew, botrytis bunch rot and spider mites, in addition to resources for organic growers. Easy-to-read tables list pesticide application rates and timing.
This publication reviews the growth stages of grapes. For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects, weeds, and disease; their rates; and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control...
This pest management guide is developed for use by vineyard managers in Oregon. It provides recommendations for chemicals, formulations, and usage rates of products that are intended to prevent, manage, and control vineyard diseases, insects, mites, weeds, and vertebrate pests. When selecting a pesticide, consider its efficacy and its impact...
