Ipm for high tunnels and greenhouse sites going into Spring, based on a good article from University of Kentucky Extension:

  1. Start clean and stay clean.
  2. Sanitation and weed control in and around structures, repair screening for insect pests.
  3. Regular monitoring and visual inspection of plants and sticky cards. Know crop history and pests encountered, and keep records
  4. Detect pest problems early, while at manageable levels.  Identify pests and for aphids and whiteflies identify them to species.  County Extension offices and Plant Clinics can help with this.
  5. Release beneficial species (natural enemies and pollinators), from reputable suppliers. Monitor populations because beneficial species require management.

The Kentucky Pest News, Weekly Newsletter had a great article about pest management in high tunnel situations, mostly biological control, as many chemical control products are not labeled for high tunnel use. Here is the link: .
Addressing mostly arthropod pests, these are good guidelines for disease control too:

  1. Sanitation and cultural controls in and around structures, which includes screening and weed control.
  2. Biweekly Monitoring – visual inspection of plants and sticky cards, keeping written records.
  3. Recognize pest problems early, before they are at critical levels. Properly identify pests; for some, identifying them to species. County Extension offices can help.
  4. Release beneficial species (natural enemies and pollinators) – monitor effects – consult with extension specialists. Beneficial species require management.
  5. Anticipate future problems based on previous crop history (refer to records).
