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.

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.

Announcements

Late Blight Spreading Across WNY Counties

7/19/17 - Late blight (LB) was confirmed in Livingston County on potato this week (the genotype is still being determined). The sample from Erie County from last week was determined to be US-23 which is sensitive to metalaxyl. All of Western NY is at risk for Late Blight infection. Severity values continue build at all stations. The frequent and continuing rainfall has been extremely favorable for the development of LB. Scout fields twice a week. All tomato and potato growers, conventional and organic, should be applying a protectant fungicides and monitoring the DSS to determine spray intervals. Remember to rotate fungicide FRAC groups and use contact fungicides in your program to minimize the chances of fungicides resistance.

If late blight is suspected act immediately! Under favorable environmental conditions late blight develops very rapidly and can spread many miles in a short period. Please take a sample for isolate identification. It is very important to track disease movement. Contact CCE Cornell Vegetable Program Specialists for assistance.

Cucurbit Downy Mildew Confirmed in WNY

Cucurbit downy mildew has been confirmed in Erie County. There have also been confirmed reports from OH, PA and Ontario Canada. If you're planning on spraying cucumbers to control downy mildew, now is the time to do it!

Characteristic disease symptoms are angular, pale green areas bounded by the leaf veins. They will turn yellow and later necrotic. Under high humidity conditions sporulation will occur on the lower leaf surface. Apply targeted fungicides tank-mixed with protectant fungicides weekly and alternated among available modes of action (FRAC code), starting when there is risk for a specific crop based on forecasting program. Refer to the Cornell Vegetable Guidelines for a complete list of products available.

For more information about the disease, watch our new video Better Know a Pest: Downy Mildew or contact Robert Hadad or Darcy Telenko.

Better Know a Pest Video Series

The CCE Cornell Vegetable Program has created 3 new, short videos about common vegetable pests: flea beetlesswede midge, and downy mildew. The videos are part of a series called Better Know a Pest. Watch for more videos as the season progresses.
