Preventive and Therapeutic Treatment
Oak trees exhibiting less than 20% crown loss from oak wilt have the best chance of responding to treatment by Kestrel.
Preventive application is more effective than therapeutic treatment. Trees in advanced stages of disease development may
not respond to treatment.
Uninfected trees will generally absorb the full amount of Kestrel: water solution within 2 hours when injected under pressure.
Consider trees exhibiting specific symptoms or those symptomless trees immediately adjacent to a diseased tree infected.
Symptomless trees separated by a primary plow line from diseased trees may be at less risk of infection. Infected trees will
absorb the material more slowly due to the vascular plugging caused by the disease. If the Kestrel water solution is not
absorbed within 24 hours, the tree is considered high risk and has a poor chance of survival.
