Sweet Corn

Sweet Corn Sweet corn is popular with consumers and growers alike. New York typically ranks in the top 5 producing states with over 19,000 acres of fresh market (2014 Vegetable Summary) and approximately 10,000 acres of processed product grown annually.

A range of varieties are available to cover the growing season and needs of each market. Fresh market corn may be planted in March under plastic or later on bare ground. Planting of processing sweet corn in New York begins around May 1st with varieties selected to maintain a steady supply into mid-September.

Cornell Cooperative Extension Educators and Cornell faculty work together annually to conduct research on many aspects of sweet corn production in the state. Below you will find educational information and results of our research trials.

2017 WNY Sweet Corn Pheromone Trap Monitoring

Again this year, the Cornell Vegetable Program will be collaborating with the NYS Integrated Pest Management Program to monitor the flights of European corn borer, Corn ear worm, fall armyworm and western bean cutworm. This information is used by NYS IPM to create weekly reports providing scouting and threshold information for fresh market sweet corn and links to resources on the major sweet corn insect and disease pests. Additionally, the information is used by the Cornell Vegetable Program to advise dry bean growers of the threat of western bean cutworm to their crop.

2016 Weed Research in Vegetable Crops, Cornell University

Twelve weed science research plots were established at the Homer C. Thompson Vegetable Research Farm in Freeville and with on-farm collaborators. Research trials included: herbicide evaluation trials in dry bean, snap bean, lima bean, beets, carrots, peas, and sweet corn; a NYFVI support trial in collaboration with Sarah Pethybridge and Julie Kikkert on evaluation of ethofumesate rates for beets; and an industry sponsored evaluation of a new products for potential use in carrot, rosemary, rhubarb, bell pepper and broccoli.

Northern Corn Leaf Blight in Sweet Corn

Northern Corn Leaf Blight in Sweet Corn

Over the past 5 years, Northern Corn Leaf Blight (NCLB) has become a common occurrence in field and sweet corn in New York State. Researchers at Cornell University are working to determine why this disease has become more prevalent. Current hypotheses include: 1) new races of the fungus, 2) new corn hybrids may be more susceptible, 3) weather patterns that favor disease, and 4) changes in the larger cropping picture. There may be a sort of an "arms race" between new races of the fungus and new corn hybrids. Western NY has seen an increase in field corn being grown and increased disease in field corn creates additional inoculum for sweet corn in the region. If NCLB becomes severe, yields may be reduced. Fresh market sweet corn growers may also be concerned with lesions that appear on the husks, as the corn may be less marketable.

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.
