  2. Station 2 – Compliance and Quarantines.  This station will provide updates on Spotted Lanternfly and Japanese Beetle monitoring and management efforts in WA.  It will also have updated information and resources on the new ESA Endangered Species Protection Bulletins (Bulletins Live!

  3. Station 3 – Mealybug Management. Learn about alternative grape mealybug management! This station will demonstrate how beneficial insects can be used in vineyards, including a presentation on how to use drones for their applications, and which insects to the best job. This station will also cover the use of pheromones for mating disruption, and will present information on the when and how to use pheromone lures in the vineyard. Presented by the James and Walsh Research Programs, Washington State University.
  4. Station 4 – Soil Structure and Composition. Learn about soil! This station will discuss tools – both modern and classic – to determine the soil structure and composition at your vineyard. It will then show how those soil properties can impact water movement in the soil, and how that might affect your chemigation and fertigation practices.
