Armyworms Marching West (08/06/20)

Large, mature armyworms are still being found on heads of 22% moisture wheat near Ross and stripping sunflower leaves and heads near Bowman. These armyworms are mature and almost done feeding. So, no insecticide application is warranted, since the cost of the insecticide and application is not likely to provide an economic return.
