Sweet Corn
Sweet corn is popular with consumers and growers alike. New York typically ranks in the top 5 producing states with nearly 25,000 acres of fresh market and 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.

True Armyworms Invading Sweet Corn!
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
For the last couple of years, we have seen True Armyworms showing up in late May early June and causing some significant damage in sweet corn and other crops. In the last two weeks we have caught low levels of adult True Armyworm moths in our sweet corn worm traps and are now starting to see the damage in sweet corn.
Watch Those Temperatures
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
Chuck Bornt Even though we haven't reached super warm temperatures yet, temperatures in high tunnels, crops under rowcovers or especially those under clear plastic hoops (such as sweet corn) can get very hot on these gorgeous bright sunny days!
Dry Fertilizer Unit Calibration
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
The first sweet corn was planted under plastic and some under rowcovers last week which is a sure sign of spring right? If you didn't get it done over the winter, now is the time to finish getting equipment prepared for planting season - especially calibrating your dry fertilizer units. Over time, the augers, fertilizer disk openers and other parts can get worn out, changing the amount of fertilizer actually coming out.

Anne Mills, Field Technician
Eastern New York Commercial Horticulture
This presentation shows a summary of 2016 peak flight times for common sweet corn pests that we monitor in eastern New York. Knowing when insects might be a peak flight is crucial to effective scouting and pesticide applications. For more pest monitoring information, please enroll in our program and be sure to read the weekly newsletters sent out during the field season.
Responding to Hailstorms
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
While no one wants to think about the possibility of hail hitting their beautiful crops just as they start to respond to the heat and take off, the likelihood that we will see more hail seems pretty high. So let's talk about it.
O-zone Injury on Vegetables
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
Hot, humid weather with stagnant air masses may lead to ozone damage on crops. Ozone warnings were recently issued for much of New York. These warnings are intended for people with respiratory problems and let them know they should limit their outdoor activity and try to stay as much as possible in air-conditioned locations. These warning are also a good indicator that ozone damage may occur in plants.

Modern Stone Fruit Training Systems Webinar
March 16, 2021
While yields of stone fruits planted to traditional orchard systems have been lagging behind our modern apple plantings in the northeast, research is actively being conducted to utilize improved rootstocks and modern, narrow training systems to increase productivity and reduce labor costs in peach and cherry systems.
In this webinar, we will be joined by Dr. Jim Schupp, Dr. Greg Lang, and Dr. Terence Robinson, as they discuss improved strategies for growing peaches and cherries in the northeast.
