Marlin, Control if any from Surround depends on the time of the month. Do you
get a weekly IPM report?. You may think it worked when if fact there may have
been a lull in moth activity during silking. If you had a 50% infestation
using
Surround this week I would say its working. If you had a 50% infestation two
or
three weeks ago I would say Surround did not help since that infestation rate
was common in the mid atlantic area in August ...Bob
