Lettuce / Leafy Greens

Lettuce / Leafy Greens Two dozen or more types of leafy greens are grown in New York, primarily for fresh market production. According to the 2007 Census of Agriculture, 224 New York farms produced 1,398 acres of lettuce. Leaf lettuce is the most widely grown with 758 acres, followed by 381 acres of head lettuce and 260 acres of romaine lettuce. Lettuce is grown for local sales as well as large wholesale markets in the Northeastern, US.

Other popular greens are spinach (247 acres), collards (96 acres), escarole & endive (75 acres), kale (57 acres), mustard greens (36 acres) and turnip greens (16 acres). Additional types for which no statistical information is available include:  arugula, beet greens, bok choy, dandelion greens, radiccho, rapini, swiss chard and watercress.

Field-grown greens are available beginning from May through mid-October (depending on the type). However, the season can be extended by growing in tunnels protected from harsh winter temperatures.

Cold Storage Chart and Reference Guide to Commercial Vegetable Storage

Commercial vegetable growers will find a Cold Storage Chart by crop type with temperature and relative humidity recommendations. The maximum number of weeks that the crop can be held under ideal conditions is provided as well.

Adapted from the USDA Bulletin #66, The Commercial Storage of Fruits, Vegetables, and Florist and Nursery Stock, growers will find information on quality, grading, sizes, and packaging, chilling and storage, and post-harvest pathology of vegetables.

The 'Late Blight' of Spinach in the Northeast. See it? Report it! Manage it!

The 'Late Blight' of Spinach in the Northeast. See it? Report it! Manage it!

Downy mildew has been found recently in spinach at several farms in the northeastern U.S. This devastating disease has not been confirmed in the region for several years, thankfully as it has been a major production constraint in California. Pathogens causing downy mildew are Oomycetes and thus are related to the late blight pathogen. They are similar in ability to produce an abundance of wind-dispersed spores capable of moving long distances and to not need leaves to be wet to infect (high humidity is sufficient), plus ability to devastate crops.

All growers with spinach should inspect their plants for symptoms promptly NOW and also in spring plantings to catch if there is carry over or new outbreaks. If downy mildew is suspected, please contact your local extension specialist and send an email to Meg McGrath.

It will be CRITICAL that all high tunnel and overwintering spinach crops with downy mildew be destroyed couple weeks before the start of the spring spinach production season in the region to avoid carry over into 2017.

Worker Protection Standard Training & DEC Special Permit Training (Wayne County)

April 4, 2017
8:30 AM - 12:30 PM English Session / 1:00 PM - 5:00 PM Spanish Session
Newark, NY

Just like last year, Special Permits (SP) will only be issued for 11 specific pesticide labels and SP trainees will have to pass a test. This will relieve the certified pesticide applicator from "on-site within voice contact" supervision of non-certified pesticide applicators when they are handling federally-restricted-use pesticides for which they hold a Special Permit. The labels that will be covered include Lorsban Advanced, Endigo ZC, Warrior II with Zeon Technology, Agri-Mek SC, Beseige, Gramoxone SL 2.0, Leverage 360, Danitol 2.4EC, Mustang Maxx, Asana XL, and Lannate LV.

Workers requiring general pesticide training/Agricultural Worker Protection Standard Handler training who do not need special permits are welcome to take the class; they will not be tested and will receive a course participation certificate.

Produce Safety Alliance Grower Training Course + Optional Food Safety Plan Writing Workshop

April 5 - April 6, 2017
April 5: 8:00 AM - 5:00 PM; April 6: 8:00 AM - 3:00 PM
Batavia, NY

Fruit and vegetable growers and others interested in learning about produce safety, the Food Safety Modernization Act (FSMA) Produce Safety Rule, Good Agricultural Practices (GAPs), and co-management of natural resources and food safety should attend this food safety training. Individuals who participate in this course are expected to gain a basic understanding of microorganisms relevant to produce safety and where they may be found on the farm, how to identify microbial risks, practices that reduce risks, and how to begin implementing produce safety practices on the farm, parts of a farm food safety plan and how to begin writing one, and requirements in the FSMA Produce Safety Rule and how to meet them.

In addition, the PSA Grower Training Course is one way to satisfy the FSMA Produce Safety Rule requirement outlined in section 112.22(c) that requires
'At least one supervisor or responsible party for your farm must have successfully completed food safety training at least equivalent to that received under standardized curriculum recognized as adequate by the Food and Drug Administration.'

Provide Input on IPM Practices and Adoption in NY

Darcy Telenko is coordinating the Vegetable Crop Pest Program in New York with the Integrated Pest Information Platform for Extension and Education (iPiPE) Project. As part of the program, a new set of tools is currently being developed to help you manage crop pests and increase your profitability.

A survey has been developed to gather your insights to help shape the development of these tools to best support your pest management efforts. In addition, the results of the survey will help the Cornell Vegetable Program and other Extension professionals get a better picture of pest management practices among fresh market vegetable growers in New York. Read more about this survey.

Hoepting Wins 2016 Excellence-in-IPM Award

For her exemplary work on behalf of farmers, not just in the rich muck-soil region of western New York but statewide and nationally, Christy Hoepting [CCE Cornell Vegetable Program Specialist] has earned an Excellence in IPM award from the New York State Integrated Pest Management Program (NYS IPM) at Cornell University. IPM weaves together a broad range of tactics that minimize the environmental, health and economic risks of pests and pesticides both.

"Christy is a star in Cornell Cooperative Extension," says Brian Nault, a professor of entomology at Cornell. "She's a gifted educator and advocate, more passionate and successful in promoting IPM practices than just about anyone I know." While onions are Hoepting's main research focus -- they're a high-value crop for New York, with annual sales upward of $40 million -- growers in western New York also welcome her expertise in cabbage, broccoli and garlic.

Hoepting has conducted hundreds of on-farm research trials in plant pathology, entomology, weed science, cultural practices and crop nutrition, presented at scores of stakeholder and scientific meetings, and published scores of articles and research papers. It's also why she scouts farm fields relentlessly, tracking every movement of insect and disease pests.

"Christy does her research on the farm in growers' fields," says onion grower Matt Mortellaro. "It makes us confident that her work will apply to our situations. She's extremely responsive, and she's always listening."

Christy Hoepting received her award on March 8 at CCE Cornell Vegetable Program's "Elba Muck Region Onion School" in Albion, NY.
