Fungal Tree Disease in Des Moines.

Is your Tree at risk of having a Fungal Tree Disease?

       While we need to remind you that preventative maintenance is the best option, we do not recommend continual, predictable treatments. Often times a pre bud swell treatment followed by a pre bud break treatment can be effective when done bi yearly. Trees that have been infected by Fungi or are infected by Fungi may need foliar applications throughout the year to limit spread followed by the pre bud treatment the following year.

Fungicide Treatment to limit Biotic Disease

       Fungi is one of the most common diseases, in Iowa, that negatively effects our Trees. The reason for flourishing Fungi is our Wet Environment. These small parasitic micro organisms then spread by contact, often becoming, one of the causal factors in Tree Decline. Most contact occurs by wind, insect, or possibly a dirty pruning tool used in the past. At Olson Tree Care our advice is to not let a fungi get ahold of your Tree. Once infected you may find the battle to be up hill and expensive with little to no ROI.

       So what are some concrete steps that can be taken to avoid being in need of Tree Removal?​ The last thing we want to have to do is remove a 60 year old Tree in full maturity when it may be avoided. Here is a list of tips that may help with your Tree Investment.


What Can You Do?

       

1. Remove bird feeders

       - Birds spread Fungi from Tree to Tree. Once we saw Fasciation, a Fungal Tree Disease, spread by birds.

      

2. Increase Vitality. 

       - A multitude of Tree born illnesses are derived from decline. Very similar to an elderly patient in the hospital who succumbs to the flu, our Trees are also Living Organisms that need  Health and Vitality through nutrition and absence of injury. ie. Hydrate when dry, feed, mulch, structurally trim when young, trim less when old, follow ANSI Standards and more.

       

3. Clean Pruning Tools. 

       - Rubbing Alcohol or a Bleach solution 1 to 9 should suffice.

       

4. Remove infected area. 

       - Restrict contact and dispose of securely. (do not mulch, this will put the spores airborne) Hiring a Certified Arborist should insure that sterilization is taking place prior to any Des Moines area Tree Trimming.

       

5. IPM. 

       - Tree Pest Management in Des Moines is best done with a Certified Arborist who considers Integrated Pest Management option. This can come in the form of Silviculture techniques providing proper spacing and ridding the area of infected Trees.

       

6. Fungicide. 

       - Chemical control in the form of Fungicide is an option to treat Fungal Tree Disease. Preventative maintenance is the best option, using a random Mode of Action, preventing resistance by the Fungi to the Treatment. In addition, using different Fungicide Active Ingredients that are applicable to your Disease likelihood may have advantages.

       

7. Insecticide. 

       - In some cases Insecticide may be a recommendation of a Tree Pest Management by a Des Moines Tree Service. When the presence of Fungi carrying insects is determined, control methods to reduce numbers may be an option.

       If you have a Tree listed in this category you may want to consider having a Certified Arborist implement steps 1 through 5. Please be mindful that step 6 and 7 should only be carried out by a Licensed and Certified Pesticide Applicator, who will possess advanced training in the many different areas of Arboriculture. In addition, an applicator must be Certified by the State of Iowa and work for a Licensed Commercial Pesticide Company. We are both Licensed and Certified by the State of Iowa and ISA.
