Many people ask how they can control the blight on a tree that is infected with the blight. One way to extend the life of an infected tree, often for a year or longer, is to apply a mudpack. This page is primarily dedicated to disseminating information about the mudpack.

One should know, though, that there are other methods of biocontrol for chestnut blight cankers.

These other methods are summarized

Massachusetts Chapter's document, TACF Staff Pathologist Dr. Fred Hebard documents the process of mudpacking, also known as a soil compress.

Here are some pictures of mudpacks. Click on the images to get larger, higher resolution photographs.
