Green Leaves Still Sticking on Soybean

Oct 04, 2022

Fall is in the air and harvest is starting up across Iowa. It has been noted soybean are holding onto their leaves. This green bean effect is more often thought of as green stems, however, this year there are more leaves and petioles staying green and attached to the main stem. Take note this occurrence may mean that soybean grain is drier than expected based on plant appearance. This green bean effect can be caused by both biotic (stink bugs, thrips, viruses, etc.) and abiotic (weather, late planting, fungicides, etc.).

Management to avoid green bean syndrome is difficult in-season because of variety of causes. At harvest, the best solution to green bean syndrome is to harvest fields when the soybean seeds are at the proper moisture content. Make sure the sickle bar on the combine is sharp and well-maintained. Slower harvest speeds will be needed to account for more soybean biomass coming through the combine.

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.
