Organic Options for Colorado Potato Beetle Control (please consult your certifying party to determine if these products are allowed first before using)

Entrust Naturalyte

Insect Control

5

1 - 2 ozs

Treat eggs at hatch or small larvae.  Repeat applications may be necessary to protect new foliage.  Do not apply Entrust to consecutive

generations of Colorado potato beetle and do not make more than

two applications per single generation of Colorado potato beetle.

Aza-Direct

(azadirachtin)

 

1 - 2 pts

Best control is achieved at the upper end of the use range.  Does not

provide immediate mortality.  Foliage contact and coverage extremely important.

 

Neemix 4.5

Ecozin Plus 1.2% ME(azadirachtin)

UN

UN

2-16 oz

15-30 oz

Most effective on small larvae, initiate application when 25% of the initial egg masses have hatched or more than 200 small larvae are found on 25 vines, continue to scout and apply at 5 to 7 day intervals during egg hatching.  Allowed for organic production if allowed by sanctioning body

Azera(azadirachtin plus pyrethrins)

UN + 3A

1.0-3.5 pints

Most effective on small larvae, initiate application when 25% of the initial egg masses have hatched or more than 200 small larvae are found on 25 vines, continue to scout and apply at 5 to 7 day intervals during the egg hatching period, allowed for organic production if allowed by sanctioning body

Trident Biological Insecticide

(Bacillus thuringiensis

 Sub. tenebrionis)

 

Bt

3-6 quarts

Initiate application as soon as eggs begin to hatch, first and second instars or up to ¼ inch in length.  Must be ingested by the insect to be effective so thorough plant coverage is essential for best results. Larvae will not die immediately but will cease feeding and die in 2-4 days.  Reapply every 7-14 days as necessary to maintain control during periods when larvae are present but during periods of heavy infestation and extended egg hatch, reapply every 4-5 days.  Do not use spreading agents, especially silicone-based spreaders. 

PyGanic EC 5.0 II

(pyrethrins)

3

4.5 - 17

 fl oz

 

Target small larvae.  Foliage contact and coverage extremely important.  Quickly broken down by UV, best when applied late in the day, early evening.

Miller Nu Film P

Na

4 ozs - 1 pint

The addition of a spreader sticker such as this one to the above mentioned products may improve spray coverage and improve control.  This material alone has no activity on CPB.

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

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.
