It’s almost the end of July, and as I have been traveling around the state, I have seen a lot of soybean fields. Some (Image 1 shown below) have weeds that have come through the herbicide program and do not even show signs of being sprayed. Others (Image 2 -treated with the SOIL SERVICE, INC. program) are clean.
In the picture above of the clean field of Liberty Link soybeans, the operator used the program that I have been recommending for the past five (5) years with Liberty herbicide.
Here is that program, applied between the V-3 and V-5 stage of the soybean grow:
- Minimum of 20 gallons’ spray solution per acre
- 24 ounces SOIL BOOST PLUS per acre
- 32 ounces MAX 72 SRN per acre
- 32 ounces LANDOIL per acre
- 16 ounces SUGAR E-BOOST per acre
- 2 gallons’ FOLIAR OPP for Beans per acre
- 32 ounces Liberty Herbicide per acre
This post emerge program has been working very well for everyone that has been using it! But, if you have fields that have a history of resistant weeds, don’t rely on just a post spray for control. Here are a few management tips that I have seen working very well.
- Spray weeds before they reach 4 inches in height – easier to kill!
- Use a pre-emergent herbicide.
- Rotate crops. That will allow you to rotate herbicides with different modes of action.
- Plant a cover crop. The competition and the heavy residue helps keep the weed pressure down.
