Stripe rust & late growth stage applications

We are reaching, if not past in some areas, the point where fungicide applications are effective in controlling stripe rust. Remember  -applications at late growth stages (past flowering) usually do not increase yield regardless of rust level. 
Also watch your applications to insure that you don't exceed the maximum rate for the season. Also carefully read if the fungicide label is using a maximum stage of growth such as Feekes 10.5 and/or a Pre Harvest Interval (PHI) of a minimum number of days to harvest.
Hopefully, with temperatures in the 80's over the next several days we will at least have some drier and warmer conditions in the fields.
