Oak Wilt Prevention
|
Oak Wilt FactsOak Wilt is a destructive, incurable and deadly fungal tree disease that is a threat to all oak tress, some of our community's most precious natural resources. It not only impacts trees but also our community. It not only kills the trees, but also can affect aesthetics, decrease your property value and is expensive to manage.
Oak Wilt spreads ABOVE GROUND through beetles: Diseased red oaks produce fungal mats generally in the spring. These fungal mats attract small beetles and spores become attached to their body. Beetles, which can travel long distances, are then attracted to fresh cuts of other exposed wounds on ALL oak trees. Oak Wild spreads BELOW Ground through root connections: Live oaks grow in dense groups with interconnected roots and this is how it is most commonly spread. Although less common, it can spread through interconnected roots of red oaks too. |
