Sweet Corn

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!

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 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.

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.
