Is the liquid in the bottle very dilute or do you add water to the solution in the bottle?
I think wine vinegar is the same mother vinegar but i feel apple cider vinegar probably has less âother stuffâ in it. Iâm am very surprised you cannot find apple cider vinegar in a health food market?
@jag44314 they are talking about regular 5% acidity store vinegar and not 30% acidity horticultural vinegar
How diluted is this solution? If too diluted, I assume it would not be effective.
Hi,
I was just curious if you have any more data points on using ACV as a prevention/treatment for FB. How was 22 and 21?
Is there anything you learned that has refined your process?
Thanks
I too am curious about your further results.
If the window for prevention has passed would it still help to spray it after the signs of fire blight have appeared?
At this point you need to cut out the fireblight and spray with streptomycin. Iâve decided that the vinegar doesnât work all by itself. But this is way beyond anything that vinegar can resolve.

You add way more water than you could if you were to spray the plant dormant.
This year I sprayed dormant plants with two part water to one part âApple Cider Vinegarâ, plants were not even stressed out by it. Next year I will be spraying one part to one part, which was suggested to me, yet I decided to be more careful than that this year.
What trees did you spray and were you trying to target fireblight or just just general tree health?
I did it for two reasons, the main reason to hopefully prevent fungal diseases in general, there is at least 3 different fungal diseases that have infected our pear trees. Of course one of them was firelight, another was âcedar-quince rustâ, and Blossom Blast (which appears to hit our one tree every year now). I even experimented spraying it on pomegranates too, because they appear to get fungal disease whenever firelight hits the area that ruins the pomegranate fruit, and there is also some fungal disease that turns the pomegranate leaves black, although does nothing else bad, and new leaves replace the black ones. Also for tree health, if they struggle even a little less that is good. I am not sure if itâs helping, or I am just getting lucky. It appears to do nothing for Blossom Blast, yet no other serious disease problems while I use the vinegar solution. Then again I could be using it at a stronger strength.

@clarkinks @coolmantoole I spray my apricots, pears, and plums with copper fungicide before fruit sets to help with leaf curl, a big issue around here. But I stand there after spraying and ever time it smells just like raw apple cider vinegar, the same stuff I use to spray on my ribs on the smoker!
