Last wee the question was:  What disease has caused this lesion that easily separates from the healthy tissue of this strawberry?

This is anthracnose fruit rot (Colletotrichum acutatum).  The decaying tissue in the lesion is held together by a network of very fine mycelium and usually separates from healthy tissue easily.  Anthracnose is usually associated with warm, humid weather and is one of the diseases we consider each year in our strawberry fungicide programs.  For more information, take a look at this page.

 

Here is this week’s question:  What insect caused this feeding damage on a canola leaf?
