Oak Wilt Disease Management
There are currently three primary approaches used for Oak Wilt
management in Austin, Round Rock, Cedar Park, Georgetown, Hutto, Kyle Buda, Austin, Round Rock, Cedar Park, Georgetown, Hutto, Kyle Buda, Austin, Round Rock, Cedar Park, Georgetown, Hutto, Kyle Buda, Austin, Round Rock, Cedar Park, Georgetown, Hutto, Kyle Buda, Austin, Round Rock, Cedar Park, Georgetown, Hutto, Kyle Buda, Temple, Belton and Harker Heights, Texas. Successful control usually depends on a integrated
program incorporating measures from all three.
The first approach attempts to prevent the formation of new Oak Wilt infection centers by eliminating diseased Red Oaks.
The second approach involves trenching or other measures to disrupt root connections responsible for the transmission of the pathogen.
The third approach is the injection of the Fungicide Alamo, into individual, high value trees. We recommend injections using Macro-infusion technology.
These measures will not cure Oak Wilt, but will significantly reduce tree
Preventing New Infections
Infected Red Oaks that die in late summer or fall should be cut and burned, or buried by early Fall or as soon
after discovery as possible. This will prevent insects from transmitting the spores from fungal mats that may
form in the Spring. If this is not possible, the trees should be injected with herbicide or deeply girdled with an ax
and stripped of bark 2 to 3 foot above the soil line. Drying of the wood before fall discourages formation of fungal
All pruning during times of high probability of fungal mat formation or in areas of known Oak Wilt infestation,
should be left to professional arborist.
Most Oaks develop mechanical problems which cause self inflicted wounding. This includes interlocking limbs,
branches rubbing on roofs or other structures and other non-phototropic trees growing up into and through the
crown of susceptible Oaks. Therefore, most unpruned Oaks are more likely to become infected by an
insect vector if the fungal mat is nearby.
Regardless of season, all pruning cuts, or other wounds to Oak trees, including freshly cut stumps and
damaged surface roots, should be treated immediately with a wound paint to prevent infestation by insect
