Mite-y Problems in Hops

In this episode of Idaho Seed Podcasts, we dive deep into one of the most persistent challenges for Pacific Northwest hop growers: the Two-Spotted Spider Mite (TSSM). As heat scales up and the canopy closes, these tiny pests can quickly devastate a crop if left unchecked.

Based on current University of Idaho Extension research and IPM best practices, we break down the life cycle of the spider mite and the strategic scouting methods needed to keep your hop cones pristine.

In this episode, we cover:

• The TSSM Life Cycle: Understanding how rapid reproduction cycles (especially in Idaho’s summer heat) dictate your management window.
• Scouting Techniques: When to start looking, where to pull leaves etc...
• Economic Thresholds: Distinguishing between a few mites and a "treatable" infestation to avoid unnecessary sprays.
• Biological vs. Chemical Control: The role of predatory mites and proper pesticide selection.
• Environmental Factors: How dust, nitrogen levels, and irrigation impact mite pressure.
