Fall Armyworm

We are in our third week of monitoring for the fall armyworm (FAW) in Ohio. Overall 22 counties monitored 77 traps across the state. The statewide average decreased over the past week to 0.98 (down from an average of 2.8 the previous week). Hardin County is currently the only county with an average above 7 moths for the week (Figure 1).
