  1. Disease Update Agents Training November 19, 2014 Smithfield, NC

  2. Outline • Disease index • Botrytis symptoms in the field • Presidio (data and proposed label)

  3. Botrytis symptoms in the field

  4. Symptoms

  5. Symptoms

  6. Symptoms

  7. Presidio fungicide on tobacco

  8. Presidion (Group 43) • Fluopicolide (novel mode of action) • Active against oomycetes (black shank & blue mold) • Bayer chemistry (marketed in the USA by Valent) • NO cross resistance to other commercial oomycete fungicides – Ridomil (4), Forum (40), Quadris (11)

  9. Presidio (con’t) • Effective on several stages of the fungal life cycle, only a few minutes after application • Xylem mobility/translaminar/antisporulant (ex. Forum) • Single site activity (high risk for resistance!)

  10. Presidio - Black shank control • 2011-2014 • Seven trials • Treatments: • Presidio 4 fl oz/a attran + Presidio 4 fl oz/a 1st cult + Presidio 4 fl oz/a layby • RG 0.25 pt/a attran + RG 1 pt/a 1st cult + RG 1 pt/a layby

  13. Presidio - Black shank control • Treatments: - Presidio 4 floz/a attran + RG 1 pt/a 1st cult + Presidio 4 floz/a layby • RG 0.25 pt/a attran + Presidio 4 floz/a 1st cult + Presidio 4 floz/a layby - RG 0.25 pt/a attran + RG 1 pt/a 1st cult + RG 1 pt/a layby

  15. Presidio - treatments * *

  16. Rate: 3 to 4 floz/ acre Must tank mix with a partner

  17. Presidio – Proposed Tobacco Label Black Shank: Use rate of 0.125 lb ai/A (4 floz/A)Maximum of 2 applications0.25 lb ai/A/season or 8 floz/A/seasonNo tank mix requirementAlternate with another fungicide that has a different mode of action on the target pathogenUse with tobacco varieties that have moderate-to-high resistance to the black shank pathogen

  18. Presidio – Proposed Tobacco Label Black shank: • At-planting program • Apply at transplanting in the transplant water (setter water) • Make follow-up treatment at layby (soil-directed)* • Soil-directed treatment must be incorporated • Post-transplant program • If a different fungicide is used at transplanting, apply Presidio 4SC once at either 1st cultivation or layby (soil directed)* *Alternate Presidio with a fungicide that has a different MOA

  19. Presidio – Proposed Tobacco Label • Blue Mold: • Use rate of 0.125 lbai/A (4 floz/A) • Maximum of 2 foliar applications • 0.25 lbai/A/season or 8 floz/A/season • Apply before disease onset or at 1st indication of blue mold in the area • Minimum interval of 7 days between applications • Must be tank mixed with another blue mold fungicide having a different mode of action

  20. Presidio – Usage • REI: 12 hours • PHI: 7 days (foliar) • Rainfast after 2 hours • PPE: • Coveralls • Shoes and socks • Chemical resistant gloves

  21. Oxathiapiprolin • Oxathiapiprolin (formerly DPX-QGU42) is the first of the new piperidinylthiazoleisoxazoline class of fungicides discovered and developed by DuPont (will be marketed by Syngenta) • Oxathiapiprolin is the active ingredient in Zorvec™ from DuPont • Active against oomycetes (black shank & blue mold)

  22. MeBr for tray sanitation • Packaging MeBr ends December 31, 2014 • That means available inventory for 2015 season
