The extended planting season this year has resulted in an extended weed management season. Even with this in mind it has been surprising about questions this late in August on what can be sprayed on soybean to control pigweed, morninglories and grass.
The biggest concern on herbicide applications made in late August is not so much the weed control this year but the carryover concern for crops in 2025. Many recrop intervals can be found on page 8 of the 2024 Tennessee Weed Control Manual. Below would be the herbicides most commonly asked about.
