Myclotect™ (compares to Eagle® 20 EW) is a local systemic fungicide effective on a broad range of common fungal pathogens that may cause unsightly leaf damage, thinning canopies, and a generally weakened and stressed appearance. This stress may also lower the tree’s amount of energy, making it more susceptible to other harmful organisms. Myclotect™ protects trees from these pathogens and increases the overall health of trees.

Myclotect™ is labeled for the following tree and shrub diseases:

Apple scab, rust diseases, powdery mildew, anthracnose, leaf spot, black spot, blossom blight & many turf diseases. Refer to the Myclotect product label for a complete list of diseases treated.

One quart of Myclotect™ makes 400 gallons of finished solution at the high rate and 1600 gallons at the low rate.

    • Bill,

      It sure does. Myclotect is labeled for cedar apple rust, but I wouldn’t treat until next spring. It will take 2-3 applications spread 14-21 days apart to gain great control. I hope this helps, if you have any other questions don’t hesitate to contact us a 888-637-6694 or

    • Roger,

      I know the container of Myclotect is HUGE! Unfortunately, we don’t have a smaller size available yet. The good news is that this large container is what the pros use, so when you purchase a vat of fungicide you are doing exactly what the guy would charge you $200 per year to do.

      We are working on getting several products in smaller sizes, and Myclotect is on that list. Stay tuned for updates to our product suite. Perhaps by spring we will have something that is more reasonable for one tree.

      Thanks for the inquiry,

    I have about 120 eastern red cedars planted on a fence row. The trees are 4 years old and have been developing cedar apple rust for 2 years now. Some are doing well and some are rather puny,I live in a forest with many crab apple trees scattered throughout. Will myclotect eliminate the galls ?

  3. C. Howard Walton says:

    Can Myclotect be used to treat the diseases of plum trees? If yes, when would one start spraying for the diseases?

  4. Lawrence Davis says:

    I have a mayhaw orchard (10 trees) and each year cedar rust destroys my crop of berries. Can you recommend a systemic fungicide and application rate/gal for spraying.

  5. Barbara Hanshaw says:

    I live in south east Michigan. I have a maple tree with black spot. Would this be product correct this? Can I use a soil drench at the beginning of growing season?

    • Barbara,

      Myclotect is a foliar applied fungicide, so it does not work as a soil drench. We don’t currently have any soil drench fungicides that will handle this problem. Good news is that the tar spot is usually not damaging to your tree. If you do want to prevent it anyway, two sprayed applications in the spring should do the trick. Of course it is tough to get good coverage on large trees, though.

    • Myclotect is registered for use on banannas and plantains, but it is only locally systemic. It needs to be applied to the leaves as they emerge to protect them from fungi. Hope this helps!

  6. grace says:

    also.. one additional question. Is it safe to eat the apples after using your product to treat cedar apple rust?

    • Grace,

      Myclotect is a great choice for cedar apple rust on apples. It will protect the leaves and fruit form the pathogen, but not stay on them long enough to affect the “eatability” of the fruit. Applications should begin in the spring and continue at roughly 14 day intervals through the beginning of summer. Be sure not to treat a month before harvest and you should be good to go.

  7. Brendan Colbert says:


    First question i presume it can treat fungul infections for large apple orchards. 2nd question could this be used on willow trees to control leaf curl and slight black spot that have developed on the leafs.?



  8. Dave says:

    My apple trees are showing a black bark area. I have the yellowing leaves but am not sure if I have scab or fire blight. I do not see any of the ” sheppard hook” look associated with fire blight. Can scab create this black appearance on the bark? If not will myclotect treat fire blight.

    • Dave,
      Hmm. If you have fireblight, then no Myclotect will not help because fireblight is actually caused by a bacterium. Bacastat is probably a better choice, but you should understand that fireblight is most often a terminal diagnosis. Can you send some pictures of your tree to for us to look at? These will help us narrow down the diagnosis.


  9. Cory says:

    Hello, I have several Swedish Aspen trees that are developing some leave diseases. I think it is black spot and powdery mildew. Can I use this product to treat yet this year. I am afraid I will lose all the leaves prematurely off a couple of them if not treated.

  10. elgin oliver says:

    I have apple trees with cedar apple rust and I live in Tennessee when what and how often do I need to spray and where do I get the spray to use please help

  11. Pat says:

    What can I use on an avocado and mango tree? Both appear to have some type of fungus on them. I was told to use a copper fungicide spray for the mango and a phosphonate fungicide for the avocado. Is this correct? What is the name of the fungicide to use for these trees. Thank you.

    • The Tree Geek says:

      Unfortunately, none of our copper or phosphoric acid based fungicides are labelled for use on residential fruit. We would be happy to help you identify and implement a solution for your problem, though. Feel free to email us at or call us at (888)637-6694.

  12. Janice says:

    Our crabapple trees have apple scab disease. I read that it’s important to clean up the fallen leaves in the fall which I plan to do by removing all the bark, leaves, etc in the flower beds by the trees. Can/should this product be used/sprayed on the ground also to be I get all the leaves so that over winter they don’t produce the spores, etc.?
    Thank you

    • The Tree Geek says:

      Hi Janice. We’d recommend just doing the foliar spray and removing as much of the debris as possible. Spraying the ground and ground cover wouldn’t necessarily provide any benefit beyond spraying the leaves.

  13. Chad says:

    I have a Flowering Dogwood that is beginning to show signs of anthracnose. It is August. Is it too late to treat the leaves? Or should I wait until spring again. Also any other special method to treating? Spraying adjacent branches?


    • The Tree Geek says:

      Hi Chad, fungal diseases need to be treated earlier in the year. Wait until spring and treat with Myclotect. Make sure you are removing any dead tissue that falls out of the tree (leaves and branches, etc) to remove any of the pathogen left in the area.

  14. Greg says:

    We have a very large crab apple with apple scab. I am tired of paying for seasonal treatment and would like to try Myclotect Since this is a foliar spray I am stumped as to how we could ever spray the leaves of such a large tree. I am wondering if you know of any tricks to reach all of the leaves. Or can the product be applied to the bark instead?

    • The Tree Geek says:

      There are a couple of considerations here. There is no simple way to spray the entire tree, and this is a common homeowner concern. There are some things you can do though. One, apple scab overwinters on dead leaves under the tree so removing them at the end of the season can help provide control. Two, the fungus tends to infect more of the bottom of the crown of the tree so spraying what you can reach can still provide some control. You will not reach the entire canopy unless you have a larger sprayer though.

  15. Pat says:

    I have 9 apple trees. Powdery Mildew has plagued them for 20 years. Every spring I prune out all growth showing mildew before they leaf out. I have tried some other fruit tree fungicides, lime sulfur, and micronized sulfur. With very little success. This product sounds perfect, but what is the dilution to water ratio, and will it keep from year to year. Thanks.

    • The Tree Geek says:

      Hi Pat, the mix rate would be 1.2 to 1.8 ml per gallon of water in your sprayer. It is a yearly application. Make sure you apply 14 days before harvest, at least (shouldn’t be a problem).

      • Pat Riley says:

        Would it be possible to convert those milliliters. into teaspoons or fractions of a teaspoon, I have no way to measure milliliters or tenths of a milliliter. Thanks for the info. I have to know before I purchase, thanks again.

        • The Tree Geek says:

          One ml is equal to 0.202884 teaspoons. 0.6 ml per gallon would be equal to 0.12173 teaspoons per gallon, 171 ml per gallon would be 34.69 teaspoons per gallon- which might be more easily measured as 11.5 Table spoons. Hope that helps, I got all of the information for conversions from google’s unit converter.

  16. Debbie says:

    I have over 400 of the Thuja green giant trees ranging from 10′ tall to 35′ tall. We’ve lost more than 20 trees to what our extension office thinks is Kabatina blight. However, they don’t have funding to come and verify. So, I’ve been spraying with Mancozeb and Bifen XTS to make sure we’re not having a spider mite problem also. We’ve done the white paper test on some of the trees and they have been infested with red spider mites. We thought all was going good and all of a sudden we have 2 more big trees that look like they are dying. There is no rhyme or reason as they are all spread out through the rows of trees. There may be 2 next to each other that have been affected a time or two, but most of the time the diseased trees are in the middle of very healthy looking trees. Will Myclotect applications help rid the trees of the Kabatina blight if that is truly what the fungus type is? Thank you!

    • The Tree Geek says:

      The best thing you can do for Kabatina is prune out the infected branches and avoid using an irrigation system to water the plants at night because the prolonged moisture makes them more susceptible to fungal growth. We don’t have any fungicides that are registered to treat the problem, and to my knowledge there re no fungicides registered to do so.

  17. Randy says:

    I have 5 crab apples,3 of them have had serious scab issues , I want to treat them myself and was wondering if one
    quart of myclotect is enough to do three rounds on each?. They are about 12 to 15 feet tall and 15 to 20 feet wide
    and do you think a pump sprayer would work or should I look for a product that can be used with a hose end sprayer ?
    Thank you in advance Randy

    • The Tree Geek says:

      Hi Randy,

      A quart of Myclotect should be more than enough to treat all 5 trees 3 times each. The pump up sprayer should be sufficient for you. Generally you are going to want to concentrate your sprays on the lower interior leaves, where conditions are more conducive for fungal growth. The leaves at the top usually get the most sunlight and airflow, so the fungus doesn’t fair to well.

  18. David Ansbacher says:

    Is Myclotect or an equivalent available in the UK? I have a very scabby James dgrieve apple on a miniature root stock.

    • The Tree Geek says:

      Hi David,

      I am sorry, but none of our products are labeled for the UK. I am not familiar with the regulations there, but I would look for something with a similar active ingredient which is myclobutanol, and check to see if it is labeled for the disease you are looking to treat.

  19. Joni Smith says:

    Hi Randy,

    I’m interested in knowing if this product, when used on my crabapple tree suffering from apple scab, would hurt the plants I have growing underneath. These would be shade loving plants like hostas, ferns and cadmium. Thanks for your help.

    • The Tree Geek says:

      Hi Joni,

      Myclotect should not harm the plants if applied correctly. You will want to minimize drift when applying to the canopy, and I cannot imagine that the amount of drift that would reach those plants would cause them harm.

  20. Joni Smith says:

    I appreciate your reply to my question. My understanding was that you need to apply the product to the lower interior leaves which would mean my plants would be exposed to the product. With all the tender loving care I’ve applied to those plants, I would hate to see them damaged or killed by the product.

    • The Tree Geek says:

      Hi Rob,

      Unfortunately, it cannot. Myclotect needs to be mixed in a pump up or backpack sprayer to ensure you get the correct mix rate applied to the foliage.

  21. steve says:

    I purchased Myclotect from you over the winter to treat needlecast on my blue spruces this spring as was recommended by your website. reading the instructions there is no mention of using for this issue and I no longer see it referenced on your website for such use. is it effective and what is the rate of application? thanks

    • The Tree Geek says:

      Hi Steve,

      I apologize for the confusion, but I would recommend Junction, CuPro, or Manzate to treat for needlecast on Spruce trees. I cannot find where on our website Myclotect is mentioned, but it will most likely not yield the results you are looking for.
