Did My Winter Wheat Vernalize?

May 29, 2025

One key difference between winter and spring wheat is that winter wheat needs to vernalize to trigger the transition from vegetative to reproductive growth. This accumulation of cold units occurs when soil and ambient temperatures are roughly between 32 and 50°F. Last fall was very dry, and despite seeding the winter wheat on time, the seed lay in dry dirt for several weeks. Several of you have asked whether this winter wheat would have vernalized to produce grain this season. Ideally, you want to accumulate those cold units in the fall after seeding, and a seedling, even if it has not reached the soil surface yet, accumulates those cold units. That accumulation will continue in the spring if needed.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
