    I live in southern Wisconsin and have lost 3-4 Oaks to the oak wilt disease. These are 100-125 year old oaks. I have had a local arborist treat my trees with a pipe looking device with a ‘fungicide’, However the trees treated have continued to die off. I asume that type of treatment is less effective than the pressurized infusion process. In watching the videw it appears that the process is fairly simple enough to allow a homeowner with reasonable shop skills to perform the infusion process. I have a new tree that is infected and the leaves are starting to drop and it is the middle of June. Will the infusion still be effective? The tree is 24 inches in diameter–how much chemical is needed.? and how much does the kit cost.
    Thank you

    • Bob,

      Are these red oaks? If so once symptoms are visible there isn’t much you can do. If they are in the white family (rounded tips) therapeutic treatment is an option. The macro infusion process, when done correctly is very effective in protecting trees from oak wilt. It is also pretty easy to apply. For preventative red oak treatments we us 20mL of Alamo for each inch of diameter, for white oak tree we use 10mL of Alamo for each inch of diameter. If you have any other questions please feel free to give us a call…we love helping people deal with oak wilt. The number is 888-637-6694, we are here to help!

        I find it funny that people say “there isn’t much you can do once Red Oaks have Oak Wilt”. I have saved hundreds of Red Oak after they had Oak Wilt. Just as most say if Live Oaks don’t take the Propiconazole within 24-48 hours there isn’t much hope. I have done my own research on this and I have left tanks on for 5 days and on the 5th day it took. This was over 5years ago and the tree is still doing fine.

        • Chris says:

          Then it is doubtful that the trees actually had oak wilt disease. Did you have a lab verify your “diagnosis”. Are you sure they were red oak trees? It is common knowledge amongst arborists that red oaks have very slim to no chance of surviving once infected with oak wilt disease. If you have “saved” hundreds then you could be making a lot of money teaching the rest of the tree care world how to do what they can’t do.

  2. William Nichols says:

    I have just had a red oak on my property cut down and removed because of oak wilt disease appearing on part of the tree. I have another oak tree about 45 feet from the tree just removed. This is a large tree that I value and want to protect it from this disease. I would appreciate any help or information you could send me. I have recently contacted Davie tree service and they advise injection with a ‘fungicide’ and gave me an estimate of $988.00 for one injection to be done for 3 years.

    Hi, hope not too late. Diseased laurel oak in Tampa, FL. Fungus (light brown/tan) overtaking, losing tree bark. Several/many limbs have fungus. Leaves turning brown and limbs dying. Limbs coming down more than usual. Canopy sparse, usually full. Would hate to lose tree, recommendations? Thanks

    • Scott,

      What percent of the tree is symptomatic? If it is more than 25%, then there isn’t much that can be done. If it is less than 25% an application of Alamo using the Macro Infusion system can be effective. It is a pretty easy process, but not one you want to try if the trees isn’t salvageable. One thing to consider is other susceptible trees in your yard. These can be protected before the symptoms appear with great success. Please feel free to contact us at with any further questions!

    I have many Pacific Madrone trees with leave spot disease, caused by fungi. I would like to try Alamo, but this species is not listed. Any advice?
