Allium Leafminer Spring Flight Has Begun

Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture

May 3, 2018

alm

On Friday, April 27th, Teresa Rusinek confirmed the first signs of adult allium leafminer (ALM) activity on garlic in Ulster County. We anticipate adults will continue to mate and lay eggs on allium crops through the month of May. As the larvae feed on tissue inside of the leaf, they can cause considerable damage to crops like scallions and chives that are marketed with green tops. The physical damage caused by adult oviposition and larval feeding also opens wounds in the leaf tissue that can serve as entry points for other pathogens that cause botrytis leaf blight and soft rot.

 We are conducting insecticide efficacy trials this year in conjunction with Cornell entomologist Dr. Brian Nault to better understand which active ingredients are most effective at reducing damage from ALM and also how many applications are necessary for acceptable ALM control. There are a number of insecticides labeled for leafminer control on bulb vegetables: the insect growth regulator cyromazine (Trigard), spinosyns (Radiant, Entrust (OMRI)), and several pyrethroids (Mustang Maxx, Warrior). Note that abamectin products (Agri-Mek), neonicotinoids (Assail, Admire Pro), and cyantraniliprole formulations (Exirel) are labeled ONLY for Liriomyza leafminers and/or thrips, but may be effective at managing ALM. Since allium species have a waxy leaf cuticle, it is highly recommended that insecticides be mixed with a compatible penetrating adjuvant (LI 700, M-Pede (OMRI), etc.) As always, follow the labeled directions for use for any pesticide.

2023 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 2023 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 Grower Interviews in Northern New York

October 22, 2022
In this episode, vegetable specialist Elisabeth Hodgdon interviews Lindsey Pashow, ag business development and marketing specialist with the Cornell Cooperative Extension Harvest New York team. They discuss findings from a series of interviews with winter greens producers in northern New York. Lindsey shares production and marketing challenges associated with growing winter greens in this cold and rural part of the state, success stories and advice from growers, and tips for those interested in adding new crop enterprises to their operation.

Funding for this project was provided by the Northern New York Agricultural Development Program. The episode was edited by Miles Todaro of the ENYCHP team.

Resources:
• Crop enterprise budget resources available from Penn State Extension (field and tunnel vegetables: https://extension.psu.edu/small-scale-field-grown-and-season-extension-budgets), UMass Extension (winter spinach budgets: https://ag.umass.edu/vegetable/outreach-project/improving-production-yield-of-winter-greens-in-northeast and field vegetables: https://ag.umass.edu/vegetable/fact-sheets/crop-production-budgets), and Cornell Cooperative Extension (high tunnel vegetables: https://blogs.cornell.edu/hightunnels/economics/sample-budgets-spreadsheets/). Use these budgets as templates when developing your own crop enterprise budget.
