I am an organic apple grower and I need a fairly large amount of Lime Sulfur in the course of a growing year. The pesticide grade Lime sulfur is very expensive and I would like to make my own.
I did a trial this year using this "recipe"
100 kg of water
20 kg of sulfur (micronized - pesticide grade)
10 kg of Lime (hydrated lime, not quick lime)
Altough I had some success, I also got quite a bit of deposits, signaling an incomplete reaction. The resulting product was not as concentrated as the commercial version.
Is there a method, or a catalyst, that would improve this simple process?
Please note that to make things more fun, any other products used will have to be approved by OMRI, so we are looking at old fashion products here...
Thanks for your interest!
