Harvest is over.
Your Vine Mealybug problem isn’t.
Post-Harvest Reality Check
If your vineyards saw contaminated clusters, sooty mold on fruit, wet bark, or October trap counts that didn't match expectations, their Vine Mealybug program had gaps.
The Challenge Isn't Your Strategy. It's VMB Biology.
Vine Mealybug hides under bark beyond spray reach. They spread during mechanical harvesting. And managing them with insecticides alone means fighting an uphill battle against:
Limited product options
Coverage challenges
Rising costs
Neighbor populations migrating into managed blocks
Research shows
Isomate VMB pheromone maintains consistent release rates from bud break through harvest.
VMB grape infestations are reduced compared to a grower standard program alone.
Flight activity
Grape infestation
Isomate VMB Mating Disruption Changes the Equation.
Blankets the field with female pheromones: No under-bark application needed
180-210+ days of protection: Covers the critical late-season flight
Equipment-proof control: Keeps working even as harvest equipment moves populations block to block
Proven performance: Field trials show consistent season-over-season pressure reduction
Limited product options
Coverage challenges
Rising costs
Neighbor populations migrating into managed blocks
Technical Specifications
120-200 dispensers/acre application rate
Available in CA & OR
It's Not Replacement.
It's Reinforcement
Add mating disruption to your IPM program and address the vulnerabilities insecticides can't.
Best practices for VMB management:
✓ Monitoring to track pressure
✓ Insecticides for knockdown
✓ Mating disruption for season-long suppression
✓ Coordinated area-wide management
