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.
