   John',
   
   I have had luck with spiking followed by topdressing. Most salesmen will try and talk you into a high rate of dacanil ZN. No luck.

   Daconil and Mancozeb do a good job at knocking it out if you stay on top of it with a regular spray interval. But in the long run, spiking and topdressing works best in my opinion. We will even hand work areas scratching it up with whatever we've got...typically a Garden Weasel.
