One troublesome weed in peanuts that we see a lot of in Tattnall County is Sicklepod, but most people know it as “Coffeeweed”.  I took this photo of one that just sprouted and came up in some peanuts.  Many growers have trouble controlling it later in the season when it gets big.  The key to getting coffeeweed under control is to spray for them when they are small, less than 3 inches in height.  We really need to keep an eye out for these weeds in the next couple of months to try and keep them at bay.  They are fairly easy to control in cotton, soybeans, and corn, because Roundup (glyphosate) herbicide can be used on many of these crops, and it works well to control it, but they are more difficult to control in peanut.  In peanuts, the product that has shown the best activity against coffeeweed has been Cadre.  2,4-DB sprays offer some suppression as well as at-crack sprays with paraquat and Storm.  However, in all of these cases, the coffeeweed need to be less than 3 inches in height for best control.
