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 here by various authors,
here by Dr. Sandra Anagnostakis of the Connecticut Agricultural Experiment Station,
and on the Connecticut Chapter website here by Timothy McKechnie.

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.
