  3. Outline • Horticultural Production Environment • Pest Damage • Integrated Pest Management (IPM) • Decision Making • Programs & Rotations

  4. Recipe for an Insect Pest

  5. The Horticultural Production Environment • Concentrated resources • Life history escape hatches • Pest adaptations • Population dynamics • Thresholds

  6. Pest Damage • Types of damage • Feeding – herbivory (direct) • Egg laying – oviposition (direct) • Nuisance - presence • Disease transmission – vectoring (indirect) • Consequences • Scouting & ecological watch-outs

  7. Scouting Watchouts Which is mite damage? Which is thrips damage?

  8. Cryptic Pests

  9. Scouting Watchouts

  10. Cryptic Life Stages

  11. Cryptic Life Stages

  12. Ecological Watchouts • Weather patterns – T, H, W • Microclimate • Crop transitions & refugia • Plant nutrition • Micro and macro-organisms • Population and genetic shifts

  13. Integrated Pest Management • Scouting • Thresholds • Cultural & mechanical tools • Biological tools • Chemical tools • Resistance Mgmt

  14. Decision Making • Setting: • Nurseries • Greenhouses • Landscapes • Turf • Thresholds & tolerance • Budget

  15. Recipe for Effective Insect IPM

  16. Case Study: Spider Mites SE US foliage greenhouse with population resurgence after knockdown miticide treatments Perennial mite population Usually just under threshold Mid-July scouting revealed rising population Preventative apps -> rescue application

  17. Case Study: Spider Mites

  18. Egg to Adult: @ 50-68°F = 28 days @ 77-95°F = 8 days One female ≈ 50 offspring Exponential growth curve @ 80°F = 13 X 106 mites/month = 13,000,000 spider mites

  19. Case Study: Spider Mites SE US foliage greenhouse with population resurgence after knockdown miticide treatments • Rescue applications of miticide • No ovicidal activity • Imperfect spray coverage • Infrequent scouting • Autumn: population peaks with reproductive females getting ready to overwinter

  20. Case Study: Tetranychid Mites Recommendation: • Improve spray coverage • Increase scouting • Scout sex ratios + presence of eggs • Scout <7 day intervals • Rotation Partners • Pylon Miticide • Another MOA Miticide • Extoxazole (MGR)* • Ultra-Pure Oil*

  21. MGRs and Oils • Etoxazole: • Beethoven TR • TetraSan • Other MGRs and IGRs – target your pest • Oils • Ultra-Pure Oil from BASF • Highly refined, clean oil • Applying oils: • Seasonally • UV more risky than humidity • Consider nighttime applications • Test plants + weather patterns

  22. Programs & Rotations • Axioms - SOPs • Rotations • Careful preventative applications • Preventing vs. managing resistance

  23. Resistance Management • Rotate MOAs in program • Avoid >2 applications with AI or in MOA • Avoid sublethal doses • Improve spray coverage • Use multifaceted approach – eg., biologicals + cultural + chemical controls; contacts vs. systemics

  24. Modes of Action – IRAC Groups

  25. Modes of Action – IRAC Groups

  26. Resistance • Prevention: • <3 applications of the same MOA • Avoid sublethal doses • Be aware of non-target insects and dose responses • Management: • Identify new MOAs • Create new rotations • Use mechanical controls • Isolate crops

  27. Resistance • Use Insect Growth Regulators – IGRs • Avoid increasing reproductives • Stop maturation • Prevent ovipositioning • IGRs or MGRs should be part of every insect rotation program

  28. Conclusion Open, dynamic systems Tools Information resources: CPS, BASF, universities, IR-4, consultants, other hort professionals
