Hi, I'm Gabriel, from Brazil!
I'm asking for some help about the preparation of JS (JADAM sulfur). In the JADAM book, it says sodium and potassium hydroxide is allowed in organic farms, based on EPA 4A e 4B list. Although, the most actualized list EPA, does not present such raw materials, so the process to obtain JS and other JADAM pesticides was compromised. So, how I can make JWA and JS with materials permitted in BR, CE and US organic certifications?
Thank you so much for the information!
