We scouted southern rust starting about 7 days post tassel about July 15-17 maybe. We didn’t get sprayed until July 22-23.
Mine got sprayed a few days later than yours, I think I would of been better off getting it sprayed earlier this year. Normally I try to spray around the 1st of August. I hit mine again @ early dent.
I've seen some that got sprayed 2 times, but earlier than mine. It looks pretty good.
Next year I'll probably shoot for 1 pass again around the 1st of August, but scout to see if disease comes in earlier. We usually don't have any disease by the 1st of August. |
One fungicide pass was not enough
