PRE-INFECTION APPLICATION
This is the start time for the next infection period that has rain after fungicide depletion time.
    Last rain hour for the infection period that started at time shown 1 column to left.  However, rain interruption may allow spray application before this time, or wind may prevent spraying until after this time. 72 hour deadline for post-infection fungicide to reach back to start time of subsequent infection period (2 cols. to left), or back to end of protection from previous fungicide spray (3 cols. to left), whichever is later.  Assumes no scab resistance.
