Oak Wilt Fungicides

There are several fungicides labeled for tree injection to help suppress oak wilt disease. The position of the Texas A&M Forest Service on these products and others like them is that Alamo ™ is currently the only fungicide that has research backed by Texas A&M University to prove that it is effective for injection and treatment of the oak wilt fungus. All similar formulations that have the active ingredient propoconizole at 14.3% concentration and labeled to be used in oak wilt control also should be effective but are not supported by research.

Fungicide injection does not stop the transmission of oak wilt through connected root systems between adjacent trees. Only severing the roots by trenching can stop the movement of oak wilt from tree to tree.
