Economic Thresholds in Washington
Questions, county scouting links, plant health guidance and field record checklists for scouting thresholds and treatment economics in Washington.
Verification checklist
Use published crop- and pest-specific thresholds, costs and expected losses; do not invent universal action numbers. Ask whether the crop diagnostic laboratory or Extension adviser actually operates in the selected county, confirm operating status, sampling or laboratory services and written terms, and confirm transaction terms in writing.
