Seeded this lawn 18 days ago. We treated with bifenthrin(granular) at time of seeding. Customer noticed grass not doing well in some spots. I picked up a handful of dead seedlings and grabbed 6 live baby armyworms! Bifenthrin effective as contact control, but the residual is not effective more than 2 weeks when watering daily for seed germination. I have NEVER seen multiple generations in same year. If we have seeded your lawn in 37205 or 37215 and you notice new grass areas quickly deteriorating, please contact us ASAP! This is major problem. Need a under 50 degree night to stop more generations. In 2017,we will have to change our program to stop this situation. A hot wet late summer year = armyworm invasion. If lawn on dry side, they won’t hit you, but seed won’t germinate. Very random, side by side yards we treat, 1 hit 1 not. Only difference is how wet they were when moths arrived in late August.
