Summary not available for this title. Record Details Catalog Search. Oak Wilt (Fungus – Ceratocystis fagacearum) All species of oaks are susceptible; however, Texas red oak and live oaks in the Hill Country and South Central areas are the most commonly affected. Post oak is rarely affected. The foliage of infected Texas red oaks turns pale green, then yellow and finally brown. Texas . Red and live oaks (in Texas) are more severely affected than white oaks. Susceptible trees may be killed within a few months after infcction. The disease generally progresses more rapidly in the homogeneous stands of semievergreen live oaks in the shallow soils of central Texas than in the mixed hardwood stands of deciduous oaks in deeper soils. Oak wilt, caused by Ceratocystis fagacearum (Bretz) Hunt, has been found in 31 Texas counties, significantly extending the southern range of the disease in the United States. The isolates obtained from 76 diseased oaks in 22 of those counties were assayed for sexual compatibility using a paired plug or spermatizing technique.
