Updates From the Field

Stands in some of the corn fields we are walking are a little spotty, with emergence problems and delays due to our very wet then very dry weather conditions. Ochs Consulting's Sion Williams and Eric Nixon, Pioneer Agronomist for the Western and Central New York region tested out Pioneer's Drone Deploy technology to do stand counts in some local fields this week. The drone gives a bird's eye view of the field, and the technology is able to look for gaps in plant emergence. Based on the photos it captures, it gives an average plant population at multiple points in the field, allowing for good decision making based on accurate information. If you'd like to learn more about how this technology works, check out this video from Pioneer.

In many of the local fields we are walking, the wheat is heading out. As the heads begin pollinating it is time to spray for Fusarium head blight. Earlier we were seeing heavy pressure from powdery mildew, but applications of fungicide have stopped the disease, preventing further yellowing of the leaves. We are also seeing cereal leaf beetles in some fields but not all. The photos below were taken locally, showing all of these issues cropping up. Unfortunately, with the dry, hot weather of a few weeks ago, many crop treatments have been compressed into a short window, with wheat, corn and hay fields all needing attention at the same time! Give us a call if you’d like us to scout some of your fields to help prioritize your fungicide applications with other crop needs.

If you have corn in the ground, you may be wondering when it is going to come up! In Trumansburg, NY we have only accumulated 60 GDUs from April 10 to April 27. Corn typically takes 100 to 120 growing degree units to emerge and depending on the weather, timing for emergence can range from 4-5 days to 4 weeks! From Elmira to Geneva, and high elevation to low elevation, we are seeing very little difference in GDUs accumulated. And nowhere in our region are we seeing more than 100 GDUs yet. Some temperatures in the 60's are in the forecast, so hopefully we’ll see corn emerging next week with the increase in GDUs and warming soil.

All corn growth stages are dependent on GDUs, and using GDUs in connection with the corn hybrid, you can predict key growth stages to time herbicide and fungicide application and harvest dates. For more information about corn emergence, you can read The Emergence Process in Corn by R.L. (Bob) Neilsen from the Purdue Agronomy Department. And for more information on corn growth stages, check out Staging Corn Growth – Field Facts from Pioneer Agronomy Sciences.

Cumulative GDUs since planting are available in the Pioneer Seeds app. As soon as your planting data is in the database, you’ll start to have access to this information. Be sure to talk with us about how to get your machine data loaded, or if you don’t have machine data, we can show you how to use the Seeds app to input your planting data.
