Fall Herbicides Can Help You Start Strong in 2014
Sep 09, 2013
There is no rest for the weary! Even with the 2013 growing season still in full swing, you’re likely starting to shift gears as you begin to plan for 2014. One way to get a head start is with a fall-applied residual herbicide application for winter weed management so you can start clean in 2014. Why?
- As we’ve seen over the last two seasons, you never know what hand you’ll be dealt by Mother Nature. This spring, many farmers had the best intentions for applying pre-emergence residual herbicides in corn and soybeans, but rain kept them out of the fields.
- Weeds are becoming more difficult to control, so using a fall-applied herbicide will help manage weed populations this winter, which can give you the advantage you need to avoid yield-robbing early-season weed competition in the spring, especially as commodity prices creep downward.
Benefits of a fall-applied herbicide include:
- Spreads out your workload and gives you an early start to spring planting
- You can concentrate on getting the seed in the ground when you get a window to plant
- Saves on the cost of an application if applied in the fall with fertilizer
- Reduces spring compaction
- Improves weed control and reduces early-season pressure from grass and broadleaf weeds in the spring
- Reduces burndown in no-till
- Helps manage against weed resistance if using herbicides with multiple modes of action
By managing weed populations in the fall, you’ll have more time and flexibility to put down a spring-applied post-emergence application on your crop.
Fall-applied Herbicide Recommendations:
- For corn and soybeans:
- Fall-applied Dual Magnum® herbicide is a great tool because it can be used ahead of Halex® GT herbicide in corn and Flexstar® GT 3.5 herbicide in soybeans to help you start strong with clean fields.
- Application guidelines (see product label for details)
- After September 30
- ND, SD, MN, WI, IA (North of Route 30)
- After October 15
- NE (North of Route 91), IA (South of Route 30)
- After October 31
- Sustained 4-inch soil temperature must be 55F or less, but before the ground is frozen
- Fall-applied Princep® 4L herbicide provides broad-spectrum, long-lasting control of winter annuals and can be followed by a post-emergence application of Halex GT.
- For outstanding burndown control of annual grass and broadleaf weeds, Gramoxone® herbicide brands are the ideal solution for resistance-conscious growers looking for effective weed control to help preserve the efficacy of glyphosate, glufosinate and the benefits of herbicide-tolerant trait technology.
- For improved burndown or residual control, Gramoxone may be tank mixed with Dual Magnum® herbicide

Bottom line: By using a fall-applied herbicide, you can save valuable time and money by preventing and controlling damaging weeds before they start.
