Congratulations to Sylvie Childress for correctly identifying the leaf issue as sunscald or sunburn. Everyone else who also guessed correctly will also be entered in the end of year raffle.
With the hot, dry, and very sunny weather, this is a common condition. Gordon Johnson wrote about sunburn in the July 5 issue of the Weekly Crop Update, which can be found here: https://sites.udel.edu/weeklycropupdate/?p=13716 and about sunscald in the current issue.
