"The twist-tie is my favorite pheromone dispenser. It’s easy to handle."

– UC Researcher

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.
