[Robert Goodson, County Extension Agent - Agriculture standing in a soybean field.] Due to the lateness of this year’s soybean crop, due to both a large number of weed acres, as well as the wet spring that we experienced, many of our beans are still late and have the option to having the over-the-top application for Palmer pigweed control.  Which herbicide you would use in the field will depend on what technology is present.  If you have Roundup® Ready beans you would end up using up to 24 ounces of fomesafen in the field. This is the herbicide Flexstar®. [Picture of soybean plants. Slide - Roundup® Ready beans -24 ounces fomesafen or Flexstar®.]

If you have Liberty Link® beans, the herbicide of choice will be Ignite.  You can use up to, 57 ounces, but the accepted application rate will be two 22 ounce instead of one big application. We seem to have better control with two smaller applications overall, but the key to the control of these weeds in these fields will be weed size. [Picture of soybean plants.

[Robert Goodson in a soybean field showing a 6 inch weed.]  If we have a weed that is two inches tall, we usually get pretty good control. If we have a weed, such as this, that is six inches tall we usually lose control with both systems.  So it’s very important, whether if using either the Roundup® system or the Liberty Link system, to control weeds when they are extremely small.  That way we have a whole lot more success in controlling this noxious weed.
