Protection all season long.

Isomate VMB uses advanced pheromone-release technology to protect your vineyard from vine mealybug — start to finish, no gaps, no reentry intervals.

Get uninterrupted coverage.

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

Isomate VMB maintains consistent daily release from day one through harvest.

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.

VMB flight comparison April–December: Isomate near zero, Grower Standard peaks in June and November.

Flight activity

2019 grape infestation comparison: Isomate VMB about 3 infested clusters vs Grower Standard about 7.

Not all mating disruption is equal.

Sprayed pheromones degrade in days. Isomate VMB doesn’t.

Isomate VMB is simple.

  1. Apply at the start of the season
    Place 150-200 dispensers per acre before vine mealybug activity begins, typically at early-season bud break.

  2. Pheromone fills the canopy
    Each dispenser continuously releases pheromone, creating a consistent cloud throughout your block that disrupts mating.

  3. Protection holds through harvest
    Release rate stays high all season. No reapplication, no reentry intervals, no spray equipment.

Best practices for VMB management:

  • Monitoring to track pressure

  • Insecticides for knockdown

  • Mating disruption for season-long suppression

  • Coordinated area-wide management

Your vineyeard can’t afford gaps in coverage.
