Strawberry Foliage Burn After Captan Application

The grower applied Captan and Sevin XLR on May 28 and noticed yellow burned leaves the next day. These pictures were taken on June 1, four days later.
No herbicides were applied this growing season.  No Sinbar, no Poast and oil.
The weather for the previous 2 weeks was cool and moist so the cuticle of the leaves was proably not well developed.

I think this is captan burn due to the surfactant in the Sevin XLR. Do you know what it is? Email me at longstr7@msu.edu.

Some leaves showed no symptoms. Lots of the foliage was burned and other leaves were yellow.
