Homemade Fungicide For Fruit Trees

 

What Is A Natural Fungicide?

 

A natural fungicide is made of organic or natural ingredients instead of harsh or dangerous chemicals that can be harmful to you, your animals, or wildlife around you. The recipes you’ll find below are all organic natural fungicides for your orchard. 

 

Does Dish Soap Kill Fungus?

 

Yes! Dish soap will kill fungus, which makes it a great ingredient for homemade fruit tree fungicide sprays! We use dish soap in many of our fungicide sprays.  

 

Why Use A Fungicide Spray On Your Fruit Trees?

 

Why you should use a fungicide spray on your trees is pretty simple, a fruit tree fungicide will help to keep your fruit trees healthy and disease-free leaving you with a better harvest at the end of the season. 

 

When To Use Fungicide Sprays On Your Orchard

 

You should spray your fruit trees with a fungicide spray at least twice, once when the flower buds first form, Then again when the buds swell but before they open.

 

 

How Do You Make Homemade Fungicide Spray?

 

Making your own homemade fungicide for fruit trees is a great way to save money, while still ensuring that you are raising organic fruit. These four natural fungicide sprays are what we use on our own trees year after year and they are super easy to make!

 

Homemade Fungicide Spray #1

 

This fungicide for fruit trees spray is super easy to whip up and can help protect your trees from fungal diseases including Powdery mildew, blight, anthracnose, Botsytis, downey mildew, fusarium wilt, rust, and scab.

 

Ingredients:

1 Teaspoon Baking Soda

1 Quart Warm Water

Small Squirt Dish Soap (we use Castile Soap)

 

Directions:

Dissolve baking soda in warm water and add soap. Mix carefully and test on the tree before spraying the whole thing. If this solution is too strong it will burn the leaves. Never spray this in direct sunlight, try to do it on days with little to no wind and in the late evening hours.

 

Natural Fungicide For Fruit Trees #2

 

This natural fungicide can be used to treat black spot, leaf spot, and scab mildew. I like to use this one on our peach trees and plum trees every season. 

 

Ingredients: 

1 Gallon Water

3 Tablespoons Apple Cider Vinegar

Dash Of Molasses

Dash of Mild Dish Soap

 

Directions:

Mix and spray in the early morning or late evening. Avoid spraying it on windy days or in direct sunlight.

 

Organic Fungicide For Fruit Trees #3

 

This garlic fungicide for fruit trees works well to fight against pathogens like powdery mildew, downy mildew, and leaf spot.

 

Ingredients:

3 Ounces Minced Garlic

1 Ounce Mineral Oil

Dash of dish soap

 

Directions:

Combine garlic and oil and leave for 24 hours. Then mix into 1 gallon of water add the dish soap and spray. Avoid spraying in direct sunlight or on windy days.

 

 

Homemade Fungicide Spray #4

 

Cornmeal makes another great fungicide for fruit trees to kill soil-borne diseases by stimulating beneficial micro-organisms. I use this on many of our roses when they have fungus. 

 

Use 2 lbs per 100 Sq. feet of horticultural cornmeal or whole cornmeal. Spread around the base of the tree and activate it with water.

 

To create a foliar spray:

1 cup of cornmeal

1 gallon of water

Soak cornmeal overnight, then strain and spray onto the trees.

 

How To Spray Your Orchard With A Fungicide Spray

 

Using a tree sprayer (we like to use a 5-gallon bucket and trombone sprayer) thoroughly cover your fruit trees with the fungicide spray. Make sure you wear, gloves, goggles and a mask to keep the spray out of your face and try to wear a hat and long sleeve shirt as well.

 

Does Rain Wash Off Fungicide Spray?

 

Whether the rain can or will wash your fruit tree fungicide spray is a really common concern, which causes people to be hesitant to spray before rainstorms. However, once dry fungicide is pretty hard to wash off and the rain has little effect on them.

    I have a ton of aphids and many ladybugs have come to help me out. I don’t want to kill the ladybugs or any of their larva. I see other places that soap kills ladybugs. Will the dash of dish soap kill the ladybugs and their babies? I also have a powdery mildew on this plum tree that I need to get rid of. However, the tree is really large and not sure if I can get it to the top. Any tips or ideas are welcome I don’t want to lose my tree.

      1. I’m having trouble finding a trombone sprayer. Most places are sold out, but I did find a syphon sprayer and thought that might work. What are your thoughts?

  6. I am wondering if these natural fungicides help with leaf curl on each trees, I am getting red/brown stuff on leaves then they curl and fall off? Not sure what to do, fruit already developing. Thank you

  7. My young pear and apple fruit trees have beautiful fruit on them, but some of the fruit has black spots, as do some of the leaves. Can I treat the trees (with the fruit on it) this time of year (late August), and if so, which one of your homemade sprays would you recommend as being best for this? Thanks!
