NEEM and oil of oregano CURED several fruit trees that were nearly dead from fire blight. One was an apple, and 2 were asian pears. The asian pear I had to cut down to the soil, and sprayed around the base and the roots, and then covered. I basicially considered it dead. Then I buried the debrid like 3' deep in an area that would never be dug up again. To my surprise they all survived, and didn't spread it to other trees. The asian pear I "killed" actually resprouted and is now 7' tall after several seasons and very strong plant. No fuit yet though. May need a companion to flower.
I also treated a very badly debarked (bear or cat) quince tree with neem and oregano and it healed. Finally, a witch hazel had a strange fungus on it and this combo helped it but hasn't fully removed it all. I am waiting to see what will happen this year. Witch hazel doesn't usually have this problem.
