Checking pressure gauge during 2014 sprayer calibration workshop

Clackamas County growers, you have the first chance to reserve your place for a hands-on workshop on sprayer maintenance, set-up, and calibration. This is a free workshop co-sponsored by Oregon State University Extension and Clackamas Soil and Water Conservation District.

Topics for the Day

  • Review sprayer operation and care.
  • Determine the fitness for use of the major components of boom and air blast systems.
  • Learn how to set-up spray equipment to make efficacious, cost-effective pesticide applications that are restricted to the intended target.
  • Demonstrate techniques and equipment to accurately determine sprayer output and speed.

Extra Benefits

Participants will have the added benefit of receiving 4 core pesticide license recertification credit hours as well as the opportunity to bring in their pressure gauges for a free check-up!

Clackamas County growers will have the opportunity to register first for this workshop, until September 30, 2015. Following that date, registration will be open to all. Class size is limited to 30, so do not wait to register!

IPM and Pesticide Risk Management

If you own a nursery in the Clackamas River watershed or anywhere near a stream, then you may be interested in attending this upcoming workshop, Combining Effective IPM and Pesticide Risk Management in Nurseries. Workshop will be held February 3, 2015 from 9 a.m. to noon at the Boring -Damascus Grange, located at 27861 SE Grange St., Boring OR.

What is it all about?

This workshop is free and offers 3 pesticide license recertification credit hours (1 core credit and 2 regular credits).

Come to learn about preventing commonly-found pesticides from reaching Clackamas Basin surface waters. Discussion will include:

  • IPM alternatives to the pesticides that are commonly used
  • effective application management for pesticides that currently have no alternatives

Also addressed will be the possibility of having to replace neonicotinoid uses in some nursery markets. This discussion will include the IPM challenges associated with returning to older chemistries that the neonicotinoids originally replaced.

Who are the speakers?

Kevin Masterson – Oregon Department of Environmental Quality, Toxics Coordinator

Update on Clackamas River water quality

Robin Rosetta – OSU North Willamette Research and Education Center , Regional Extension Educator

IPM that addresses frequently detected pesticides and neonicotinoid replacement

Paul Jepson – Integrated Plant Protection Center, Director

Simple guidelines for minimizing pesticide risks

What to do next?

We recommend an RSVP, so we have enough seats and snacks! Call 503-210-6000 or e-mail

Windsocks Help Reduce Pesticide Drift

Since 2000, monitoring conducted by Oregon Department of Environmental Quality has detected pesticides in Clackamas River tributaries at concentrations that exceed benchmarks set to protect fish and invertebrates.

Pesticides of Concern

The active ingredient and product names for the pesticides that were found to exceed benchmarks are listed below.

  • simazine: Princep
  • chlorpyrifos: Yuma and Lorsban Advanced
  • bifenthrin: Capture 2EC, Brigade 2EC, Brigade WSB, Wisdom
  • diuron: Karmex, Direx
  • oxyfluorfen: Goal2XL, Goal Tender
  • chlorothalonil: Bravo Weather Stik, Chloronil 720
  • dichlobenil: Casoron

Help for Agricultural Producers

Windsocks available to Clackamas producers

Windsocks available to Clackamas producers

To help agricultural producers apply pesticides without losing chemicals to drift from wind, Clackamas County Soil and Water Conservation District is offering calibrated windsocks.

Windsocks are attached directly to the tractor for real time information to make quick, more accurate decisions on spraying practices for reducing drift. They are calibrated to indicate wind speed from 2 to 12 miles per hour.

How to Receive a Windsock

If you are a producer in Clackamas County and are interested in receiving a windsock for your sprayer, contact the District at 503-210-6002. We are happy to provide these windsocks. Producers may be asked to participate in an anonymous survey after they have used the windsocks for a number of application events. The District is partnering with the Integrated Plant Protection Center to conduct a study that will help us evaluate whether using the windsock is helping growers make better, more accurate decisions while in the field spraying.

Pesticide Collection Event Was Tons of Success!

Ready to collect and safely transport old, unusable, or restricted pesticides.

The Tualatin and Clackamas County Soil and Water Conservation Districts co-hosted an Agricultural Pesticide Collection event on Saturday March 8, 2014, at Wilco Agronomy in Cornelius, Oregon. Working with a number of partners, the Districts received 15,822 pounds of waste (7.911 tons) from 29 individual farmers, golf course owners, and other producers throughout Washington and Clackamas Counties during the one day event.

Clean Harbors Environmental Services conducted the anonymous registration for the event and will dispose of the collected waste. Additional partners in this event included Clean Water Services, Crop Production Services, the Joint Water Commission, Oregon DEQ, OSU Extension, Oregon Department of Agriculture, the Tualatin River Watershed Council, and Wilco.

Safety was a primary concern in hosting and scheduling the event, which was originally planned for February 8, but had to be rescheduled due to the poor winter weather. “We were concerned about having people drive their loads of pesticides into the event in the snow,” says District Manager Lacey Townsend. “Although it was a challenge, rescheduling the event helped us to ensure that all of these chemicals were safely and properly disposed of, which was our main goal.

The 29 anonymous participants agreed that rescheduling the event was worth the trouble. Many participants in the collection event inherited out-of-date pesticides when purchasing a property. These chemicals may be no longer useful, or in some cases, no longer legal. Pesticide collection events like this one are often held anonymously to allow these producers to feel comfortable doing the right thing. As one participant said, “It was good to be able to get rid of things we cannot use – some people would just bury this stuff but that’s not how we want to do things!”

Craig Nordling of Clean Harbors Environmental Services, was pleased to continue this event’s sterling safety record. “The event ran well with no injuries which is what I care about most at the end of the day,” said Craig. Another collection event in Washington County is anticipated if future funding can be secured.
