Fungal Mats And Oak Wilt in Austin, Texas
|
|
Fungal mats are reliable indicators for
diagnosis of Oak Wilt in Red Oaks. They most often form in the spring on Red Oaks that developed advanced symptoms of Oak Wilt, the previous late summer or Fall. Red Oak infections in late Summer or Fall usually do not produce fungal mats due to high tempature and low moisture conditions in the soil. Fungal Mats can be found by looking for inconspicuous narrow cracks in the bark, leading to hallow areas between the bark and wood. They often have a distinctive odor similar to fermenting wood. Fungal mats can be exposed by chipping or pulling away the loose bark. |
