Many of the same caterpillar species found in soybeans are also at sub-economic levels in peanuts. The one exception is fall armyworm. Another “flush”, about 20-30 small larvae per row foot, was found in peanuts near Shorter, AL (Macon county) yesterday (August 24). These armyworms do not always occur in all fields on a given farm. The same products – pyrethroids, Intrepid and Dimilin also provide good control of fall armyworms in peanuts. The quickest kill will come from pyrethroids while the longest residual will come from Intrepid and Dimilin.
