Temperature Impacts Corn Emergence

By Pam Knox

If you plant corn or work with farmers who do, you are probably well aware of the importance of watching soil temperatures before you plant. But if not, you might be interested in these Indiana PrairieFarmer stories that describe how soil temperature and moisture can affect corn germination and emergence. Farmers need to be aware of not only current soil temperature but also the forecasts for both the daily temperature range and potential rainfall. The soil temperature range is also affected by both the soil type and whether it is no-till or has a lot of debris on the surface. If the temperatures get too low, the seed takes a long time to germinate and emerge from the ground, causing spotty field coverage.

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

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.
