Leeks

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.

A New Pest for the New Year in Western NY: Allium Leafminer is Here to Stay
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program

In the fall of 2023, Allium leafminer (ALM) decimated leek crops in Orleans, Genesee, and Niagara Counties in New York. After its first detection in North America near Lancaster, PA in 2015, this invasive insect pest originating from Europe quickly established itself in southeastern New York, New Jersey, western Massachusetts, Delaware and Connecticut. It was only a matter of time that it would become established throughout New York. We are now assuming that ALM will occur throughout the 14-county Cornell Vegetable Program region in 2024. And, unfortunately, it is here to stay. Here is what Allium growers need to know.
Video: New York State Produce Auctions

Currently, there are 8 produce auctions in New York State. These auctions are aggregation points that allow local farmers to sell their produce in wholesale lots to buyers from across the region. To document the economic impact of produce auctions on agriculture, local businesses, family farms, and produce buyers, the Cornell Vegetable Program worked with Harvest New York to survey top sellers and buyers.
A new Cornell Vegetable Program video shares general information about produce auctions, how buyers and sellers use the auctions to expand their businesses, and how local communities benefit from them.
Crop Cooling and Storage
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program

On-Farm Cold Storage of Fall-Harvested Fruit and Vegetable Crops is an in-depth look at the planning and designing cooling for late season and winter storage but it also is useful for general cooling as well. This was written by Scott Sanford, Distinguished Outreach Specialist, UW-Extension, and John Hendrickson, Outreach Program Manager, Center for Integrated Agricultural Systems, University of Wisconsin-Madison.
Video: Farm Food Safety as if Someone's Life Depended On It
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program

This video is an overview of Good Agricultural Practices (GAPs) through on-farm risk assessment. Cornell Cooperative Extension, along with the National GAPs Program and the New York State Department of Agriculture and Markets, has developed and implemented a nationally-recognized training program in GAPs to prepare New York growers for the marketplace's increased vigilance in food safety. You can learn more about that program through this video, as well as updates on the Food Safety Modernization Act (FSMA), and economic information on the implementation of GAPs collected from growers through extensive interviews.
Extending the Harvest Season with Fall Production
Robert Hadad, Extension Vegetable Specialist
Cornell Vegetable Program

Late season production starts in mid spring. For a successful crop, start with a detailed plan. Designate an area specific for late season production so that management can take place in one spot rather than all over the farm. This will make cultivation, pest management, using row cover, and harvesting more efficient to manage.
Leek Moth Control and Information
Christy Hoepting, Extension Vegetable Specialist
Cornell Vegetable Program

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.

Upcoming Events
Food Safety Lunch and Learn Webinar Series
February 11, 2025 : Part One: What's Going on with Food Safety?
NYS Department of Agriculture and Markets FSMA inspectors are expected to step up farm visits this season. Why are they showing up on the farm asking about FSMA? Aren't we exempt? This noontime hour we will discuss the purpose of the farm visits and what produce farmers need to know.
February 18, 2025 : Part Two: What Counts as Food Processing?
In this session, we will discuss what counts as processing and what doesn't. Stories of inspectors coming to farmers markets and auctions telling some growers certain products can't be sold usually without much explanation. We will try to make some sense of things and clear up some misunderstandings so hopefully the upcoming season goes smoothly.
February 25, 2025 : Part Three: Traceability - Benefits for Food Safety and Beyond
Can having a traceback process for your produce (and other farm products) make good business sense regardless of FSMA regulations? We will (try to) make the case for farms to have some sort of traceability mechanism in place.
Allium Pests!
February 26, 2025
Presented by Christy Hoepting (CCE Cornell Vegetable Program) and Ann Hazelrigg (Univ. of VT), this webinar will focus on organic management of pests and diseases of onions, garlic, leeks. The webinar is part of a series supported by the Transition to Organic Partnership Program.
