Fighting Fire Blight and Other Bacterial Diseases with Hydrogen Peroxide

Do you have trouble with bacterial diseases on fruit
and ornamental plants?

You might want to try using a spray bottle of 3 percent
hydrogen peroxide to combat the problem. You can apply
the hydrogen peroxide directly to plant leaves, bark and buds
where the blight or disease is visible.

The hydrogen peroxide is a great bacteria killer, and will not
harm most flowering shrubs and fruit trees. (Some extremely
tender plants can become slightly “burned” but this is rare.)

Howard Garrett of the Dallas News includes this little snippet
about using hydrogen peroxide in his columne today:

It soon will be time for my fruit trees
to bloom. I have two ‘Moonglow’ pears that suffered
from fire blight last year.

I bought copper soap fungicide for use during
dormancy. The directions for this spray indicate
that it also can be used on blossoms. Is that
a good idea?

I’m not a fan of copper products.

Try this: Spray 3 percent hydrogen peroxide now
and again when the trees are in bloom. Hydrogen
peroxide is very effective on other bacterial diseases
and should work in this case. Let me know how it
turns out.

Seems hydrogen peroxide has a lot more ways of being useful
in the garden or around the house than most of us thought!
