Hi JADAM Team,

I am referencing the official JMP dosage table (based on Representative Cho Young-sang's formula).

According to the table, for 100 L of water:

Decyl Glucoside (②): 200 ml

KOH (③): 100 g (dissolved in 50 ml water)

JS (④): 200 ml (I currently use 180 ml, which matches this closely)

I would like to ask a technical question regarding this mix:

If we completely skip the Potato Microbial Culture step (①), can we use Decyl Glucoside (200 ml) + KOH (100 g) + JS (180–200 ml) per 100 L of water directly as a safe and effective fungicide/bactericide for grapevines?

Does removing the cultured microbial toxins significantly reduce its overall fungicidal efficacy, or is this 200 ml Decyl Glucoside + 100 g KOH + 180 ml JS combination fully sufficient for routine disease prevention on grapevines?

Thank you for your guidance and support!

Best regards,
