Proven Results for Superior CRS Protection

We’re different from your average mating disruption solution. Our Variable Rate Mating Disruption (VRMD) means the busier the pests in your orchard, the more pheromones we release.

  • Timed pheromone release when your crop is most vulnerable: No more wasted pheromones — get targeted protection when the pest is active and during male flights.
  • Better late-season control: Late-season pheromone coverage reduces crawlers for effective year-over-year population control.
  • Research-backed results: The research we completed in 2021 showed that Semios CRS mating disruption provided reduced crawler counts, little to no twig infestation, and reduced fruit damage when compared to alternative, hand-applied products.

“One of our ranches was the worst we’ve ever seen for California red scale. For 2 years we worked to get the problem under control, and last season we were able to pull some sprays - the first time we’ve ever reduced a spray, and it worked. In the end, we’re saving time and a bit of money, and the Semios mating disruption treated blocks are the cleanest they’ve ever been. As a research guy, I need agtech companies to prove it to me for 2 years before I’ll believe it works. One isn’t enough. Semios is one of the rare ones that works."
