Black Knot can be eradicated from your fruit tree with the use of Black Knot Be Gone. See our pictures and videos of trees with improvements in 2-3 months.

The Black Knot disease embeds itself into the tree and through the bark after 2-3 months the black crumbles away in this case study.


  • I sent you an email with several questions, and no reply. Here are my Q’s:
    Found your info on Black Knot and your “all natural product”. We have a couple of plum trees with this black knot on it and had the tree pruned by an arborist who cleaned the tools also. But it’s back worse than ever. Couple of Q.s:
    1. For two trees how much do we need?
    2. One treatment or more?
    3. How deep do we drill the holes?
    4. If it doesn’t work do you refund?
    5. What about infected plums that have dropped into the bed below the trees? Use Copper or Neem Oil there?

  • I live in toronto canada. Where can i obtain this product from

  • Hello, I had boghten your product about two months ago and my flowering plum tree seemed to be growing new leaves and became the fullest and brightest it has been since this black knot disease has taken over. My plum tree now sadly looks to be awful the disease is really taking over and most of the tree is gone! I know everyone I have spoken with said they have given up on trying to save the plums but do you know of any tips to prolong the trees live span ?
