Does Black Layer Form When Corn Is Frosted?
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-35/does-black-layer-form-when-corn-frosted
Black layer is the stage in corn development at which kernel growth ceases and maximum kernel dry weight is achieved (also referred to as “physiological maturity”). A killing fall frost prior to physiological maturity can cause premature leaf death or wh ...

Frosted Forage Precautions
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-35/frosted-forage-precautions
Jack Frost will be visiting us soon. Several forage species can be extremely toxic soon after a frost because they contain compounds called cyanogenic glucosides that are converted quickly to prussic acid (i.e. hydrogen cyanide) in freeze-damaged plant t ...

Soybean Pod Shattering
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-35/soybean-pod-shattering
Soybean pod shattering is not completely understood. Through breeding efforts (beginning approximately 5,000 years ago when soybean was first thought to be domesticated), soybean plants have gained pod shattering resistance (Dong et al., 2014). However, ...

Five Things to Know about Fall Herbicide Treatments
There is plenty of information on fall herbicide treatments in the C.O.R.N. newsletter archive and on other university websites. Our philosophy on this has not changed much over the past decade. A few brief reminders follow: 1. When to spray? Anytime ...

Prussic Acid Testing in Forages
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-35/prussic-acid-testing-forages
Some forage species can develop prussic acid poisoning potential when harmed by frost and management practices should be followed to prevent poisoning of livestock (see accompanying article). If doubt remains regarding the safety of the forage, it can be ...

Soybean Aphid Prediction for 2015
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-34/soybean-aphid-prediction-2015
Two observations on soybean aphids surprised us in 2014. First is that we saw soybean aphids at all. Since 2001-when soybean aphids were first detected in Ohio-we have had aphid outbreaks every other year (i.e. in odd numbered years). But in 2014, soyb ...
