Variety Thinning Recommendations for mature trees - 8 to 12mm fruit size
Variety Thinning Recommendations for mature trees - 8 to 12mm fruit size
Varieties where I like Maxcel+Sevin
• Gala - 64 oz Macxel /100 gallons TRV dilute = 128oz Maxcel per acre for a fully grown tree + 1pt Sevin/100 gal TRV dilute = 2pt Sevin per acre for a fully grown tree
• Empire - 48 oz Maxcel /100 gallons TRV dilute + 1pt Sevin/100 gal TRV dilute
• Jonamac - 48 oz Maxcel /100 gallons TRV dilute + 1pt Sevin/100 gal TRV dilute
• Macoun - 48 oz Maxcel /100 gallons TRV dilute + 1pt Sevin/100 gal TRV dilute
• Fuji - 48 oz Maxcel /100 gallons TRV dilute + 1pt Sevin/100 gal TRV dilute
• Red Delicious - 36 oz Maxcel /100 gallons TRV dilute + 1pt Sevin/100 gal TRV dilute
• Bartlett Pears- 96 oz Maxcel /100 gallons TRV dilute
• Bosc Pears- 48 oz Maxcel /100 gallons TRV dilute
Varieties where NAA works well
• McIntosh - 2oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Honeycrisp - 3oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Cortland - 2oz Fruitone L/100 gal TRV dilute
• Golden Delicious - 4oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Rome - 2oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Jonagold - 3oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Gingergold - 1oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Idared - 2.5oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Pink Lady - 1 or 2 oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
• Northen Spy: 2oz Fruitone L/100 gal TRV dilute + 1pt Sevin/100 gal TRV dilute
Chemical thinning program for Young Trees:
• For newly planted trees where you desire to totally eliminate the crop try a heavy rate of Maxcel (64 ounces) + Sevin (2pts) + Oil (1pt) /100 gallon TRV dilute when fruit size is 8-10mm.
• For 2nd year trees where we want a small crop use only hand thinning and the Cornell young tree thinning guide to adjust crop load.
• For 3rd year trees use Sevin alone + follow-up hand-thinning.
• For 4th year trees use 1/2 of our suggested full rate of NAA + Sevin or Maxcel+Sevin.
• For 5th year trees use 75% of a full rate of NAA + Sevin or Maxcel+Sevin.
• For 6th year trees use a full rate of NAA+Sevin or Maxcel+Sevin.

Upcoming Events
Blind Industry White Wine Tasting Workshop
April 1, 2025 : Blind Industry White Wine Tasting Workshop
Germantown, NY
This event is a blind wine tasting for ENY grape industry members to get feedback from fellow growers and Cornell Enologists on unfinished white wines (hybrid, vinifera, etc.)
We respectfully request that only professional winemakers or commercial vineyard owners attend, as space is limited. Limit two wines per winery/vineyard.
Pre-registration is required. For questions, please contact Jeremy Schuster at jds544@cornell.edu
