Armyworm Occurrence

The above picture shows armyworm damage to bermudagrass rough.  Symptoms appear as if the turf was drought stressed but upon closer examination, worms were present.  Armyworms were not as abundant last year compared to this year due to an excess amount of rainfall over the past couple of months which aids in the hatching of armyworm eggs.  The agronomy staff has been scouting and spraying these areas with the insecticide Bifenthrin.

Armyworms turn milky white after an application of Bifenthrin

Birds are a good indicator that armyworms might be present
