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.

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.

2016 WNY Sweet Corn Pheromone Trap Monitoring

2016 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.

Student Research Internships Working with the CVP

The Cornell Vegetable Program is looking to hire two student research interns this summer to assist in scouting fresh market vegetables in western New York. This internship will start in May, working alongside Darcy Telenko, as part of the iPiPE CAP (Integrated Pest Information Platform for Extension and Education, Cooperative Agricultural Project) internship program. iPiPE is committed to investing in the coaching and development of future agricultural scientists/extension educators through a limited term internship experience in an applied environment. The purpose of the program is to learn how to scout for pests in the field and contribute observations to the iPiPE platform. These positions are 5-month appointments (39 hours/week) and will be located in the CCE Erie County Office (East Aurora, New York).
