Predicting Leaf Development in Corn Using Accumulated Heat Units
When estimating yield losses in corn due to hail, frost, and other types of plant injury, it’s essential to establish the stage of plant growth at the time damage occurred. It’s also important to know corn stage of development in order to apply post-emerg ...

The Risk for Scab Continues to be Low as We Enter Early Grain-fill
A June 2 Update: Wheat across Ohio is now between anthesis and early grain-fill. Barring a few late-planted fields in some parts of Northern Ohio that are now at the flowering growth stage, most of our wheat reached anthesis late last week and during the ...

Ohio State Continues Corn Nematode Field Survey
Co-Authors also are Abasola Simon and Anne Rugh. This season, researchers from the department of Plant Pathology at Ohio State will again be sampling corn fields for nematodes. This is the third and final year of a three-year project to determine which ne ...

Should seeding rates be adjusted for delayed corn plantings?
Past university research indicates that optimal plant populations for early (mid to late April) and late planted (late May to early June) corn are similar. Based on results of these studies, most extension agronomists recommend that final plant population ...

Corn Replant Issues
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-15/corn-replant-issues
Localized ponding and protracted saturated soil conditions have adversely affected corn in many fields across Ohio. Heavy rains have also resulted in soil crusting which is contributing to reduced emergence. Producers confronted with poor stands due to th ...

Scab Risk Continues to be Low, but Rain is in the Forecast
https://agcrops.osu.edu/newsletter/corn-newsletter/2014-15/scab-risk-continues-be-low-rain-forecast
For wheat flowering today, May 27, the risk of scab is low, according to the prediction took. Several fields across south-central Ohio reached anthesis over the weekend, and since conditions were fairly dry in most of those areas, the risk tool also predi ...

Early Season Soybean Damage- Frost, PPO, or Disease?
Spring 2014 has been quite challenging with wet soil and cold temperatures. We’ve received several calls and e-mails regarding soybean seedling damage (from those who have actually been able to plant). It appears that some soybean fields were hit with a ...

Wheat Approaching Critical Heading and Flowering Growth Stages
This week, wheat is heading or will begin to head in fields across Ohio, particularly in southern and early-planted fields. In fact, in some southern fields, the crop was at full head emergence (Feekes 10.5) at the end of last week (May 15-17) and will li ...
