My experience taught me that such pesticide use, along with the inevitable spray drift and the proximity to the neighboring properties represented a significant risk for exposure. We got permission from local residents to set out pesticides drift sample trays in their yards before the spray. 

ODA Arrives for Oversight

An Oregon Department of Agriculture (ODA) investigator was present to observe the orchardist pesticide application on August 3rd and 4th, which was the last pesticide application for the year. For those days the orchardist used an insecticide called Asana XL to treat moths whose larvae can bore into hazelnuts and destroy the nut. 

The ODA investigator took lots of photos to document the spray and noted the temperature throughout the day, as pesticides can often volatilize at higher temperatures. The Willamette Valley was under an extreme heat wave during this time.  

The investigator noted open windows at homes next to the orchard with fans blowing air inside during the spray. The ODA investigator documented barely legible notes by the orchardist that served as two years of pesticide application records at the orchard.  

After The Spray

The next day we collected our sample trays and plant leaf samples from the backyards after the spray happened and sent them to a lab to test for pesticides. When we received the results from the lab, we were not surprised to see low levels of pesticide residue detected on one of the samples. We sent the lab results to ODA to show that pesticide drift had reached the homes outside the orchard. The ODA returned to collect their own vegetation samples from the yard at the same residence where we found drift and also inside the orchard. The resident had since removed the squash plant where we took our samples and the samples collected by the ODA nearly a month later did not detect pesticide residue at the residence. However, high levels of pesticide residue were still present on the orchard trees. This pesticide is labeled to cause skin irritation and there is ZERO tolerance for residue on food and it should not be accessible in a public park. 

Willamalane Responds

In September, a month after the last spray, Willamalane reached out to Beyond Toxics and interested community members and invited us to participate in an Ad Hoc Advisory Committee to make recommendations to the Willamalane Board of Directors about changes in orchard management practices. Committee members included a representative from the National Parks Service, who advised the committee about the historic values of the Dorris Ranch Park and orchard and cultural landscape. A horticulture expert from OSU provided options on Integrated Pest Managament (IPM) practices including pest trapping and monitoring, and less toxic pesticides for each pest throughout the growing season. An organic hazelnut farmer provided a presentation about organic management of hazelnuts through harvest, processing and marketing. Beyond Toxics advocated for better signage and public notice to neighbors and park visitors, better recordkeeping, and most importantly, we focused on developing a community value of non-toxic public spaces.

On December 1, 2021 the AdHoc Committee recommended that the District transition the Dorris Ranch hazelnut orchard to organic management. The Willamalane Board of Directors voted on December 8, 2021 to immediately discontinue using the most hazardous pesticides used in the orchard in favor of less toxic products. They also requested Willamalane staff to obtain further information about the cost of transitioning to organic.
