At the end of last week I noticed some browning in the new turf around my building and saw army worms on my sidewalk. To be honest, I've never seen them before. From what I understand is that they are usually a southern problem. I have since seen them on the last 3 lawns that I have done service calls for brown areas. I treated with bifenthrin at 1oz per 1000 and it seemed to do the trick but, the devastation that is done in 24hrs is insane! What is everyone's protocol on these? I have 1600 accounts and I'm wondering how the hell to deal with them? Is it too late once I see the damage?
