Propiconazole is a systemic fungicide widely used for the control of oak wilt, however, the long-term efficacy of this fungicide has not been well established and treatment effectiveness may be below levels that justify its use in many situations. OAK WILT TREATMENT. Controlling oak wilt involves stopping both underground and above-ground spread of the disease. Rinse inside and out with clean water.

Oak wilt can spread from infected trees to healthy trees through root grafts between nearby oaks and by insects that carry spores of the fungus from one tree to another.Root grafts. Oak wilt is an aggressive disease that affects several species of oak trees. Soon after Oak Wilt was identified in Texas, a program was initiated in the Department of Plant Pathology and Microbiology at Texas A&M University to develop a strategy to combat Oak Wilt. leaves falling off). Some oak species, including northern pin oak and Texas live oak, often grow in large groups of similar-aged trees that share a common root system. Overall, Alamo targets and treats: You may not have an oak wilt risk or there may be other circumstances that would cause this procedure to be inappropriate. Oak Wilt Part 2: Prevention & Management Strategies Introduction Oak Wilt (OW) is caused by the “invasive” fungus, Ceratocystis fagacearum, and is an increasingly important issue of concern for the forests and landscapes in This is known as DBH (diameter at breast height) in the arborist world. In addition there are cost and aesthetic disruption considerations with trenching. If the tree has more than one trunk, each one is measured and the total becomes the “diameter". Alamo is the industry standard fungicide for the management of oak wilt and laurel wilt disease. By this method the equipment is used to cut roots to a depth of at least 4-1/2 feet along a boundary line beyond which there are only healthy oak trees unaffected by oak wilt. The tree takes up the fungicide and water mixture. The tree number is entered into our "tree tag database" that records information about the treatment and the tree. Disrupting the connections between the roots of infected and healthy trees limits the spread of oak wilt and is an effective control measure. Alamo is the flagship product with the best and most research and product manufacturing quality control measures and oak wilt is a primary pathogen and possibly the worst tree disease ever. Confirm with a qualified Arborist, or Biologist that this procedure is appropriate for your tree. In addition, the disease movement is often not the same in all directions.

It was not until the early 1980s that a fungicide containing Propiconazole (the active ingredient in Alamo®) injected into symptomatic and non-symptomatic trees was found to be effective in controlling symptom expression. Most trees that are treated preventatively don't experience a high degree of internal damage. Healthy oak trees can be treated using the fungicide Propiconazole 14.3 to prevent lethal infection by oak wilt disease. 4. This would generally include wearing rubber gloves and safety goggles during all mixing, injection and cleanup work. For smaller or thinner trees, a lesser dosage may be appropriate. These beetles feed on the stick sap oozing from the mats and in the process pickup Oak Wilt spores on their bodies. 2010 map shows the distribution of counties with oak wilt disease infestations over the central and eastern US.

If your oak tree(s) appear to be in trouble, its problems may be caused by a fungus There are approximately 2 to 2.5  injection points per DBH spaced evenly around the tree. Fungicide Injections We use macro-injections to inject Alamo (propiconazole), a systemic fungicide, into the vascular system of the tree. The disease is caused by fungus and is especially harmful to red oaks and Live Oaks. While the fungicide can kill the Oak Wilt fungus, internal damage is not reversible. This is the only protocol with scientific data proving positive results. Trees that are infected with or have died from oak wilt disease should be removed and properly treated to prevent development of spore mats. Two ways to control such an outbreak are 1) Conduct trenching to disrupt the root connections between roots of infected and healthy trees 2) Treat healthy trees by injection of a fungicide so that they resist infection by the oak wilt fungus. It does not protect the healthy trees from infection through above ground tree wounds by the sap beetles. Infected trees in early stages of symptom expression can be treated, but their chance of recovery is poorer. Trees that die in summer should be removed the following winter before spring which is when new spore mats can develop. Disinfect Chemjet® injector and drill bit by washing and scrubbing in diluted bleach solution or Lysol disinfectant solution. The result is a program utilizing both cultural and chemical approaches to disease management. No other product has been as extensively researched and field tested for the control of these diseases. If there is leakage push the nozzle in harder to seal. Oak wilt is a devastating exotic disease, killing some trees rapidly in a single season. The treatment containers are filled with the proper fungicide and water mixture. The fungus, Ceratocystis fagacearum, invades the water conducting tissues (xylem) and induces the tree to clog its own vessels, preventing the normal flow of water. Other oak species, including White Oak, are affected to a lesser extent. The triazole fungicide Propiconazole is effective in management of the oak wilt disease; it possesses systemic and some curative properties against certain fungal diseases.
