Leeks

Leeks There are roughly 30 acres of leeks grown in New York annually. They are an edible member of the Liliaceae or lily family. They are tender and have a mild onion flavor with a slightly sweet edge. Leeks may be planted in late February to March for harvest in early- to mid-summer. Alternatively, they may be planted in July for harvest in late fall/early winter.

Leek is an expensive crop to grow, because it is labor intensive. Hand labor is required for all stages of production including: transplanting, weeding, harvesting, washing and packing.

Information on cultural practices and pests of leeks can be found in the Leek Pest Management Strategic Plan.

2021 Leek Variety Trial: Beyond Megaton

Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: November 19, 2021

Year two of the leek variety trial brought completely different weather and challenges, and brought forth some different high performing varieties. However, 'Chinook', 'Lancia' and 'Defender' proved to be top performers in both years, demonstrating disease resistance, vigor, and high uniformity. This year we replicated the varieties, allowing for statistical analysis, but the tremendously different growing seasons lead us to recommend looking at results from both years as worth considering. The notable challenges from this season were very regular rains during July and parts of August, and subsequent very high disease pressure. The previous season was much drier and disease pressure was negligible.

Last Modified: August 25, 2021

The invasive fly pest, allium leafminer (Phytomyza gymnostoma), has been established in the Northeast since 2016 and has caused crop damage as far north as Washington County, NY, as far east as central Connecticut, and as far west as the Finger Lakes region of NY. In research trials, the fall flight has caused damage to over 98% of leeks that were not covered or managed with insecticides.

Allium Leafminer Active in Southern Pennsylvania

A new invasive insect pest in the Northeast known as the Allium leafminer (ALM), Phytomyza gymnostoma, damages crops in the Allium genus (e.g., onion, garlic, leek, scallions, shallots, and chives) and is considered a major economic threat to Allium growers. Originally from Europe, ALM was first detected in Lancaster County, Pennsylvania in December of 2015 and in New Jersey and New York in 2016. As of fall 2017, ALM activity has been confirmed throughout eastern Pennsylvania, New Jersey, Delaware, southeastern New York as well as Thompkins and Suffolk counties.


Onion and Seed Corn Maggot Concerns in a Cold, Wet Spring

Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: April 18, 2018

Last year we saw a lot of problems with root feeding damage from maggots early in the season, which has growers on edge about pest pressure this year. Seed corn maggots can damage a variety of crops, and in previous years have been observed on everything from sunflower shoots in the greenhouse to pea seedlings and onion transplants in the field. Onion maggots are more particular, and will only feed on allium hosts.

Leek Moth Control and Information

Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program

Last Modified: May 24, 2012
Leek Moth Control and Information

Leek Moth was detected in four home gardens in Plattsburg, NY in 2009. It was first detected in Ontario, Canada in 1997 where it has become problematic especially to small-scale, organic growers in eastern Ontario and to commercial producers in western Quebec, who have limited insecticides available to them.

Leek Moth continues its spread to more farms and gardens across the U.S., a new comprehensive website is available to aid in the identification and management of this pest. This Cornell website features maps of the distribution of leek moth, protocols on insect monitoring and identification, best management practices for farms and home gardens, a photo gallery of damage symptoms and a comprehensive resource section.

Visit the Leek Moth website.

Announcements

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.

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

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.
