The 2018 season could be another rough year for growers. Current fall delivery bids are around $3.60 per bushel for corn and around $9.60 for soybean. These low prices are similar to situations in 2016 and 2017, which means you’ll need to maximize your yields this year so you can break even.
However, there are a number of things you can do to achieve above-trend yields in both corn and soybeans, starting with an effective weed management strategy. In combination with recommended cultural practices, choosing a proven herbicide program is crucial to winning the battle against yield-robbing weeds.
It’s important to choose a program with overlapping residual herbicides containing multiple effective sites of action (SOAs) in both the pre- and post-emergence applications.
For control of tough weeds in corn, we recommend using Acuron® or Acuron Flexi corn herbicide. Acuron is a combination of 4 active ingredients with 3 effective SOAs, while Acuron Flexi is a combination of 3 active ingredients with 2 effective SOAs. Both products provide application flexibility, with the ability to spray from 28 days preplant to 12” corn for Acuron, and 28 days preplant up to 30” corn for Acuron Flexi. A two-pass system can also include a post-emergence application of Halex® GT corn herbicide for an additional site of action.
For broad-spectrum control of weeds in soybeans, we recommend making a pre-emergence application of Boundary® 6.5 EC, BroadAxe® XC or Prefix® herbicides, each containing 2 SOAs. Additionally, you can follow up Boundary 6.5 EC and BroadAxe XC with a post-emergence application of Flexstar® GT 3.5, which also includes 2 SOAs to combat weeds that are difficult to control with glyphosate alone or those that are resistant to ALS-inhibitors.
Not only will these products help you achieve above-trend yields, but using them correctly will also help prevent the development and spread of resistance.
