Genetics, gene flow, and distribution of pesticide
resistance traits were examined for organophosphate (OP)
resistance in three beneficial phytoseiid mites. Levels
and genetics of OP resistance in Amblyseius andersoni
were examined first. Laboratory strains from Italy and
Oregon, USA, were compared in susceptibility to
insecticides used in western Oregon fruit...
This report, Oregon pesticide use estimates for small fruits, 1990, is the first of five statewide pesticide use surveys covering: small fruits, tree fruits, seed crops and special crops, vegetable crops, as well as small grains, forage crops, and livestock. Oregon Pesticide Impact Assessment Program’s objective is to complete one...

The Oregon Water Quality Decision Aid (OWQDA) is
a first-tier screening tool that allows you to make a broad
determination of the likelihood that a specific chemical,
when applied to a specific Oregon soil, will move through
the soil and contaminate groundwater. This determination
is called the groundwater vulnerability rating.
Prevention of groundwater contamination by agricultural
chemicals requires an understanding of the complex
processes that control pesticide movement below the soil
surface. Through this understanding it is possible to try
to predict which areas may be most vulnerable to
contamination. The many models that have been developed to
characterize pesticide...
