Sunburn on Strawberry Foliage
Just a quick note and pictures to add to our growing catalogue of physiological damage to strawberries and caneberries.
Depicted below are several instances of sunburn and/or heat damage to strawberry. The top two pictures were of a strawberry plant up next to a wall getting full sun during the entire hot spell we had last week, so it is without a doubt it is heat and sun which caused the damage depicted in the pictures below.
These are good features to recognize for the diagnostician in the field.

Heat/sun damage on fruit. Note similarity of leaf symptoms to the two examples above.
