This morning when I went out to mow the plots at the farm, the SR 1020 was hammered with dollar spot. It appeared to be pretty consistent on all the mowing heights. Since we have not started applying all the treatments, I did not worry with rating the plots for severity. The weather has been warm and humid the last couple of days. We have been having some pretty severe thunderstorms over night and some during day time hours.
We went ahead and sprayed Headway (azoxystrobin + propiconazole) on the green to try and curratively control the small outbreak. The green is kept pretty lean on N compared to many locations, so reduced N may also help give Sclerotinia an edge.
Hopefully this application will whipe it out and we can move forward. This may be a good sign that we will be able to get some data on Dollar spot severity differences if they are visible with our treatments.
Peace out.
