Potatoes

Potatoes Potatoes are grown all across NYS, though the largest farms tend to be located in Western NY, the Finger Lakes Region and on Long Island, on deep, fertile, light- to medium-textured mineral soils, and on muck (organic) soils. Potatoes are grown on small, medium and large farms, for retail, wholesale (east of the Mississippi) and organic markets, for both fresh market and processing into chips, and for certified seed potatoes. Most growers store some of their crop for winter sales. Varieties include round whites, red-skinned potatoes, yellows, and a smaller acreage of a wide variety of specialty types, such as those with blue or red skin and flesh, fingerlings, etc. Potatoes are one of the highest value vegetables in NY, grown on 16,000 acres, with an average value of about $54.9 million recently (2014 Vegetable Summary).

Potatoes have many serious insect and disease pests. Late blight can be a devastating disease, capable of completely destroying an unprotected crop within 3 weeks in wet weather, and rotting the tubers. Late blight was the major cause of the Irish Potato Famine. It also affects tomatoes. New, more virulent strains of late blight fungus began showing up 20 years ago and the disease has been harder to predict and control ever since. Early blight is a common fungal disease on both potatoes and tomatoes which survives over-winter in the soil. Colorado potato beetles can cause serious defoliation if crops are not rotated up to a quarter mile from where they, tomatoes or eggplant were previously planted. They can rapidly become resistant to commonly used insecticides. Tiny, sucking leafhoppers move up from the south each June on weather systems, and can cause severe leaf burn and yield reduction. Aphids can also be a production problem as well as carrying viral diseases that can affect potatoes grown from saved seed.

Best Management Practices for Dickeya in Potato Production in the Northeast

Best Management Practices for Dickeya in Potato Production in the Northeast

Potato seed tubers harboring Dickeya dianthicola are the only confirmed source of this pathogen. It does not appear to be able to survive in soil (including in crop debris) from one growing season to the next. Consequently, rotating with a non-susceptible crop is not a necessary component of the management program. Best management practices listed in the PDF are encouraged to minimize potential losses from Dickeya.

North American Certified Seed Potato Health Certificate (NACSPHC)

The emergence of Potato Virus Yntn, which causes tuber necrotic ringspot disease (TNRD) in susceptible varieties, and the emergence of blackleg Dickeya, both serious seed-borne diseases, are very important reasons why you need to get a copy of the North American Certified Seed Potato Health Certificate (NACSPHC) for each lot of potato seed you buy.

Organic Production Guides

Organic Production Guides for fruits, vegetables and dairy are available through the NYS Integrated Pest Management (IPM) program. They outline general practices for growing vegetable and fruit crops using organic integrated pest management techniques.

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.
