Dear Agricultural Stakeholders,
You are receiving this email as a contact for your organization. If there is a better contact within your organization, please forward this email to them.
Beginning this spring, the WSDA Pesticide Compliance Program will increase our field presence with a focus on surveillance, in addition to responding to complaints. We will specifically look at crop areas that use airblast sprayers, but will look at other types of pesticide applications as well if drift is observed.
Our goal is to improve compliance with existing laws, rules and pesticide labels that require pesticide applications to stay on the target site. We want to see airblast sprayers performing properly to avoid off-target drift, which will reduce complaints and exposures.
Be aware that you may be violating pesticide laws and rules if you are applying pesticides in any of the following ways:
- With an airblast sprayer that creates excessive plumes above the canopy and/or the spray is drifting off target site.
- In winds strong enough to cause drift.
- During inversion conditions.
- Not shutting off the spray at end of the row or not doing it in time
This spring we will focus on documenting incidents of off-site pesticide movement and issue warnings, along with providing information for follow-up technical assistance. In cases of human exposure or larger drift incidents, we can issue fines of up to $7,500 per violation.
Please be careful when applying pesticides, and work with our agency teams as they help you to keep pesticide applications on site.
If you have questions, contact Tim Schultz, Acting Compliance Program Manager at 509-994-0936 or email@example.com.
