An overview of how a variety of wild and managed bees and their pollination activities are affected by pesticide application. Provides guidelines for how beekeepers, growers and pesticide applicators can work together to prevent bee poisoning.
Documentation of the side effects of pesticides on
arthropod natural enemies has expanded rapidly since the
1950's as part of an increase in non-target side effects
literature. Most reviews have been based on empirical
analysis of selected literature. The SELCTV database was
developed to make a larger information base accessible...
Environmental toxicologists and public health officials are responsible for assisting in the identification, management, and mitigation of public health hazards. As a result, there is a continued need for robust analytical tools that can aid in the rapid quantification and characterization of chemical exposure. In the first research phase, we...
Groundwater contamination on irrigated land is of concern in this nation
and around the world. In order to reduce the potential of groundwater
contamination by agricultural practices such as irrigation, fertilizer and pesticide
application, vadose-zone monitoring and sampling are needed. The main
objective of this study was to evaluate impacts...

Large burrowing owl (Aihene cunicularia) populations exist in areas of intensive agriculture in California, and pesticide exposure has been identified as a potential threat to population persistence. I evaluated breeding season use of agricultural fields by adult male owls using radio telemetry, and examined egg contaminant residues to estimate population-level...
The pages of this Continuing Education Book contain the papers presented on the Oregon State University campus, March 22-24, 1971 at which time several hundred individuals gathered to learn the requirements for the Oregon Public Employee "Special Applicator" license test. The purpose of this Short Course on Pesticides, Pest Control...
Volatile loss rates of pesticides from turfgrass were measured using the Backward-Time Lagrangian Stochastic Dispersion model (Flesch et al., 1995). Solar radiation, ambient temperature, surface temperature, relative humidity, wind direction, and wind speed were monitored continuously. Growth regulator was applied to the turf plot several days before pesticide application to...
Are pesticides hazardous? That's up to you! This publication outlines safe use, storage, and disposal of pesticides and provides links to more information from the Oregon Department of Environmental Quality and National Pesticide Information Center.
This report is largely concerned with the toxicity of Sevin (carbaryl) and Dursban (chlorpyrifos) on aquatic organisms. "The general objective of this research is to investigate the effects of various pesticides, which might be expected or are known to occur in estuaries, on the larval and adult stages of estuarine...
Commercially managed honey bees pollinate a variety of crops in the Pacific Northwest, including tree fruits, berries, cucurbits, and crops grown for seed. This activity is economically significant. In 2004, the value of bee-pollinated crops in the region was approximately $1.7 billion. Nationally, the value of bee-pollinated crops in 2000...

Four factors govern the potential for groundwater
contamination by pesticides passing through the soil:
• Properties of the soil
• Properties of the pesticide
• Hydraulic loading on the soil
• Crop management practices
The procedure described in this publication helps
you assess the potential for any specific pesticide
to travel through any specific soil to reach
groundwater.
An experimental protocol to determine the effects of temperature and light on the dissipation of xenobiotic substances in pesticide deposits is presented. A factorial design laboratory experiment is used to develop isothermal models of the dissipation of compounds over time in authentic pesticide deposits on excised leaves arid glass microscope...
