With spring approaching I have recently been reaching out too peers at other courses in my local area for advice on controlling/suppressing worm castings on my greens. My course in located in south Georgia...Vidalia to be more specific (Yes, we're famous for our onions

) During spring and summer the worm castings are horrible...so much that when mowing or rolling greens the unit must be stopped and rollers wiped clean after nearly every pass. In the past I've sprayed Carbaryl, Sevin SL brand, and have seen control for about 2-2.5 weeks. The Carbaryl works great, but the short amount of control time makes for many repeated applications that can get very pricey! Does anyone have any suggestions/advice on other ways to control them? Is there any cultural practices that could help control them? I'm not sure if anyone else encounters the same problem or in the same severity but asking for a little advice never hurt! Thanks!!
