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

Initiate application as soon as eggs begin to hatch, first and second instars or up to 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.

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.

If you have questions, please contact enychp@cornell.edu
