Seeds absorb moisture within hours after planting and begin the germination process almost immediately. When corn seeds absorb water colder than 50°F, imbibitional chilling or cold shock may occur.
These three symptoms of cold chill may be evident at emergence, during the growing season and at harvest time:
Absorbing cold water causes the cell membranes to rupture and release fluids that provide food sources for soil pathogens. These can invade developing seedlings and dramatically harm the germination.
When a seed imbibes cold water, the early season vigor of young corn plants may be negatively impacted. Weak root systems with gnarled primary roots might result.
Wet soils drain kernels of their energy reserves, so seedlings that struggle for a week or more to emerge may have erratic emergence and uneven growth. Many of these fields experience disappointing yields at harvest due to reduced stands and decreased seedling vigor.
Call into the Latham® office and we will get you connected with one of our agronomists. Happy Spring!

Tar Spot is a corn fungal disease that has been infiltrating the Midwest within the last few years. Tar spot has the capability to severely impact yields up to 30%. Concern about the intensity of this fungus grows as researchers learn more about it. We urge farmers to scout their fields through harvest for tar spot since this fungus can survive over winter year to year.
Tar Spot Identification
Tar spot will show up as small, raised blacks spots, on the upper and lower corn leaves. The raised black spots are also known as stromata. If severe enough, it can spread to leaf sheaths and husks. Typically, it will start lower in the canopy and move upward. Tar spots are usually accompanied with a yellow halo or fish-eye effect around the black spots. Note the stromata, cannot be rubbed off unlike a common or southern rust pustule.
The Importance of Scouting
This corn fungus has nearly made it across Iowa and is continuing to spread in Wisconsin, Illinois, Indiana and Missouri. Tar Spot likes cool temperatures and humid conditions, with prolonged leaf wetness or heavy dew and will concentrate towards the middle of the field. It can cause lodging and hasten maturity.
Final Thoughts
This is one of the variables in farming we continue to learn about. Scout now and start planning for next season. Product selection is key when fighting these variables year to year and important to integrate into your plan for the next growing season.
