Variety Thinning Recommendations for mature trees - 8 to 12mm fruit size

May 15, 2017

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.

Supervisors are critical to the success of farm businesses. They have a major impact both on employees' daily work experiences and on the production performance of the business. The  agricultural Supervisory Leadership certificate helps farm supervisors and managers learn and apply human resource management practices and leadership skills that foster rewarding workplaces and drive business results. Confident managers who thoughtfully apply leadership and management skills improve employee performance, develop teams, reduce employee turnover, and increase employee engagement. The courses within the certificate program will offer extensive practice and engagement activities to build confidence and skill sets.

July Next Gen Meetup at Bowman Orchards

July 21, 2022
Rexford, NY

The July Next-Gen meet-up is focused on marketing. We will provide everyone who registers with a resource guide to farm stand marketing. The Bowman's have a farm store, U-Pick berries, sunflowers, apples and pumpkins as well as a commercial apple orchard. We encourage you to check out their website (Bowman Orchards).

Young farmers are welcome to attend, the focus of the program is farmers who are in the process of taking over a farm from the prior generation (whether family or not). Please pre-register by July 18  so that we know you are coming and can have enough food for dinner and resource materials.

2022 Spotted Wing Drosophila Monitoring/Management

All berry farmers are watching for monitoring reports that indicate Spotted Wing Drosophila (SWD) adults are in their region. Mid-season berry crops should be sprayed as soon as berries begin to ripen unless you've elected to use insect exclusion netting.

- For general information about SWD, and to enroll for free monitoring reports, visit the Cornell SWD blog https://blogs.cornell.edu/swd1/.
- Click here for the 2022 Quick Guide for Pesticide Management.
- For some great instructional videos and fact sheets on insect exclusion netting, visit the University of Vermont's Ag Engineering blog.


Resources from CCE ENYCHP!

We are developing new ways to connect with the CCE ENYCHP team this year! We have a Youtube page located at this link. Check out videos on Table Grape Production, Pest Updates and the 20 Minute Ag Manager - in 4 Minutes series. 

We have a Facebook Page here as well as an Instagram page. We keep these places updated with current projects, events, and other interesting articles and deadlines.

There are also text alerts available. Fruit and vegetable farmers in 17 Eastern NY counties can now receive real time alerts on high risk disease and pest outbreaks texted directly to their cell phone. The Eastern NY Commercial Horticulture program, which is supported by local Cornell Cooperative Extension associations, will now offer text alerts to those that enroll in our program in 2019. 

The text alerts will be reserved for important crop alerts that could impact management decisions immediately. For instance, if there were an outbreak of Late Blight in the area, this would be transmitted to vegetable growers.

Farmers can choose the crop for which they wish to receive updates. Additionally they can request that Ag Business Alerts be sent to them. These alerts might include due dates for crop insurance deadlines, market opportunities etc.

Winter Greens Research Review

March 23, 2022
Winter Greens Research Review
March 17, 2022

Episode description:
In this episode, vegetable specialists Ethan Grundberg, Elisabeth Hodgdon, Jud Reid, and grower Leon Vehaba discuss winter greens production in Eastern New York. They highlight research results from the past five years that aimed to develop nitrogen fertility and heating recommendations for winter high tunnel greens production. Leon discusses his lessons learned from his experience at the Poughkeepsie Farm Project and how he made changes to his greens production as a result.

Funding and support for the research trials discussed were provided by:
Organic nitrogen fertility management in winter spinach (Willsboro Farm and Pleasant Valley Farm trials): New York Specialty Crop Block Grant Program, Northern NY Agricultural Development Program, Toward Sustainability Foundation, Paul and Sandy Arnold of Pleasant Valley Farm, Mike Davis of the Cornell Willsboro Research Farm, and Amy Ivy and Andy Galimberti of the CCE ENYCHP.

Nitrogen dynamics and yield response to minimal supplemental heating in high tunnel winter production: Northeast SARE Partnership grant and the Poughkeepsie Farm Project.
