Mastering the Principles of Herbicide Resistance

Enhance Your Weed Management Expertise and Earn Pesticide Recertification Credit

Herbicide-resistant weeds are a growing challenge in modern agriculture, threatening crop yields and increasing management costs.

This "Mastering the Principles of Herbicide Resistance" course equips pest management professionals with the knowledge and strategies needed to combat this critical issue effectively.

Designed for licensed pesticide applicators, consultants, landscapers, and others in pest management, this course provides actionable insights and one (1) pesticide recertification credit upon completion.

And because it's on-demand, you can learn at your own pace through an interactive and practical online format.

Course Overview

This course is part of a groundbreaking series from Oregon State University that addresses pesticide resistance, one of the most pressing issues in pest management today.

Leveraging the latest science and research, it delivers practical, region-specific solutions that go beyond traditional approaches.

You will leave with the actionable knowledge to safeguard their operations against herbicide resistance while contributing to sustainable agriculture.

Stay Ahead in Pest Management:

Gain up-to-date, science-based insights into herbicide resistance.
Learn techniques tailored to the Pacific Northwest and Oregon’s unique agricultural ecosystems.
Enhance your skills with interactive knowledge checks and practical learning modules.

Solve Real-World Challenges:

Understand the mechanisms driving herbicide resistance and how to mitigate them.
Develop proactive strategies to protect herbicide efficacy in your operations.
Identify and address application failures with confidence.

Stand Out as a Certified Expert:

Renew your pesticide certification while mastering advanced pest management techniques.
Position yourself as a leader in sustainable and integrated pest management.

What You Will Learn

By the end of the course, you’ll have the skills to:

Define herbicide resistance and tolerance, including their practical implications.
Explain the importance of herbicides in modern agriculture and the impacts of resistance.
Recognize and utilize the Herbicide Resistance Action Committee (HRAC) mode of action classification system.
Distinguish between cross-resistance and multiple-resistance in weeds.
Identify factors influencing herbicide resistance development and application failures.
Implement surveillance, monitoring, and resistance testing techniques.
Perform dose-response experiments and confirm herbicide-resistant weed populations.
