Defining IPM • Many definitions are used.
• Simply put, a proactive and multifaceted approach to pest management that is grounded in applied ecology.
• Demands a robust understanding of the biology of your crop, its pests/diseases, and how both are influenced by the environment.
![Page 4: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/4.jpg)
Cannabis Specific Considerations • Unique crop and unique cultivation environments
• Viable control strategies vary dramatically with crop age
• In many cases traditional action thresholds don’t translate well
• Compliance is Key

Components of a Cannabis IPM Program Pest Monitoring/Identification
Control Strategies:
Structural/Environmental Controls
Resistant Varieties
Cultural Practices
Biological Controls
Compliant and Responsible Pesticide Use

Responsible Pesticide Selection and Use • Understand the different types of pesticides available in your market and how to
use them compliantly.
• Use products, techniques, and strategies that maximize damage to pests while minimizing risk to your crop, your employees, your consumers, and the environment.

Pesticide Use and Cannabis Testing • Look to your State’s Department of Agriculture, Department of Health, and
Cannabis enforcement body for State specific testing regulations.
• Understand how pesticide use can influence your test results.
• Understand how testing regulations differ between State markets and adapt your pest management techniques to fit your State’s standards.

KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING
Evolution of Pesticide Use and Misuse
![Page 9: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/9.jpg)
Prior to 2015
• Questions – what can I use?
• No resources to dedicate a focused effort on outreach or inspections
• 2012 first complaint, disgruntled employee,
violations found, CDO (WPS, Azamax, Avid and Floramite)
![Page 10: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/10.jpg)
February 2015
• Denver fire magazine article prompts a
discussion
• Denver Fire, DEH, communicate visual
observations and concerns for safety regarding pesticides
• March 2015 first formal complaints filed
![Page 11: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/11.jpg)
Rules Established
• PAA Rule effective March 30, 2016 – Broad label language – Tolerance exempt a.i. – Express food uses – A.I. has allowed uses on tobacco
• 25(b) w/express food uses • Approved 24(c) • Broad authority to prohibit use of products • Nov 2017 – Pesticide Act Rule update
![Page 12: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/12.jpg)

Adulterated Products • Mighty Wash - Pyrethrin • 25(b) - Guardian Mite Spray
– Oregon and Colorado confirmed presence of Abamectin
• Azatrol – 6/2017 - Oregon detected Permethrin,
Bifenthrin, Cypermethrin, Cyfluthrin, Chlorpyrifos, Malathion
– VDA running Colorado formulation samples • Violations of the PAA vs. Public Health
Concerns
![Page 17: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/17.jpg)
Future Issues and Approaches • SLN 24(c) registrations
– 6/2017 EPA denied CA, NV, VT, WA – Research and Demonstration – CDA Pesticide Act Rule limited use registration
update for R&D
• Use below labeled rates to avoid detection – CDA finding residues below LOQ, but above
MDL – Pest resistance concerns
![Page 18: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/18.jpg)
Future Issues and Approaches
• MED required sampling – Screening for 13 products – CDA will continue screening for 90+
• Compliance verification – CDA will be inspecting and sampling entities
previously found in violation – WPS inspections – random sampling – Initial CVIs showing continued misuse
![Page 19: Keep it Clean: Integrated Pest Management and Testing · KEEP IT CLEAN: INTEGRATED PEST MANAGEMENT AND TESTING Moderator: Meg Collins, Good Chemistry SESSION SPONSOR: ... its pests](https://reader033.fdocuments.us/reader033/viewer/2022042221/5ec78a86e415e810350f9a26/html5/thumbnails/19.jpg)
Future Issues and Approaches
• Communication of positive results – MED – CDPHE / DeH / other
• Case workload prioritization – Dependent on personnel (June 2018) – MJ vs. conventional case workload
