Presentation Transcript

  1. EBPM Status • Much research is funded annually • Profitability issues remain, EBPM systems often not as profitable or are too risky compared to existing IPM systems • EBPM generally relies on collective efforts (e.g. cooperatives, public oversight, etc.) which have yet to be accepted on a wide scale.

  2. Farmscaping • The practice of designing and maintaining habitats that attract and support beneficial organisms, used to improve crop pollination and to control pest species. • Emphasis on landscape ecology for targeted objectives. • Many examples are available. Here are a few.

  3. Many similar themes along these lines Here’s a small sample. Follow the links to read a little about each one & get the idea. • Permaculture • Biointensive Pest Management • Regenerative Agriculture • Biodynamic Agriculture

  4. Notes on First Hour Exam • Scheduled for Monday, Feb. 23 • Covers everything through this point • Chapters 1 – 7 in text • All assigned reading • Lecture notes • Be sure that you can do the exercises • Structure will be short answer (~2/3 of grade), longer answer (most of the rest). Might be some matching. • Note that the course has been re-organized since last time so old exams are helpful only for structure. • Exam starts promptly at 8:00 & papers are collected at 8:50.

  5. Pest Management Tactics & Strategies • Covers chapters 8 – 17 in text • Includes all major tactics categories: • Biological control • Cultural control • Pesticides • Mechanical/Physical controls • Behavioral-based control methods • Regulatory-based concepts • Also includes all factors necessary for choosing/deciding among controls • Monitoring methods • Decision tools

  6. Pest Management Decision Categories • Tactical vs Strategic • Preventative vs. Curative • In-Season vs. Intra-Season • Control vs. Non-control (i.e. monitoring) • Single Dimension vs. multidimensional • Temporal: Single Period vs. Multiperiod • Biological: Single spp. (pest) vs. Multiple spp. (pests, beneficials, other non-targets) • Economic: Immediate payback vs. multiple economic considerations.

  7. Who makes IPM Decisions? • Growers who manage the pests? • Consultants who make recommendations to growers? • Extension specialists who develop educational/training materials? • Researchers who decide which topics to research? • Administrators who decide which things to fund? • Others?

  8. Pest Management Strategic Plans Decisions about how IPM needs to advance in a particular cropping system. A planning tool. • Driven by national programs • Closely associated with Crop Profiles and Crop Timelines • Provide a framework for IPM decisions • No specific format, but most include: • Pest profiles for each important pest • Management tactics currently used • Additional needs in research, extension, training

  9. Assignment • Split into groups of 3 • Each group finds a Pest Management Strategic Plan • Distribute the web site for the plan over IPM-L by Thursday, Feb. 19. • Each group discusses their plan in class on Wed., Feb. 25 • Suggestion: One person discusses the pests, one discusses the tactics, one discusses the needs.

  10. Most Decisions are Tactical & Follow a Procedure • Identify pest • Determine pest population density • Evaluate potential damage • Review available control tactics • Consider possible interactions with other pests • Evaluate legal/environmental issues • Make a decision

  11. The Decision Itself • Must rely on a priori objective criteria. Often an economic framework. • Four possibilities • No action • Reduce Pest Population • Reduce Crop Sensitivity to Damage • B & C above • Follow-up to confirm expected outcome

  12. An Alternative View to Fig. 8-1

  13. Identification: Focuses on early seasonality factors • Pathogens – Identification of conditions leading to disease often more important than identifying the pathogen itself. • Weeds – Seedling identification is the main issue • Arthropods – Knowing when immatures will be present often a key to identification of pest problems.

  14. Monitoring • Synonymous with “Scouting”, “Sampling”, “Pest Surveillance” • Normally conducted to gather information needed by a decision tool • Types of decision tools that using monitoring info include tools that: • Time preventative treatments • Determine whether curative controls are needed • Determine whether either of the above were effective • Select specific measures from several choices

  15. Monitoring Determines: • Identity of pests • Phenology • Age distribution • Number or size of population • Absolute (#/unit habitat or area) • Relative (#/unit effort) • Qualitative (Scaled from “low” to “high”)

  16. Requirements of Monitoring Methods • Simple to use • Fast • Inexpensive • Applicable to a broad range of pests • Reliable for decision making purposes

  17. Reliability for Decision Tools Max Tolerable Pest Pop. I II I Max Tolerable Pest Pop. Pest Population on Next Sample Date III IV Pest Population on One Sample Date
