Top answer
From the KNF library
Corrected October 2026: some figures in this answer are not Master Cho’s teaching (for example spraying 25 gallons per acre, Microbes at 1,200 pounds per acre, or Fuel at 1:3000). See Corrections for what he taught.
Drake ran a drone spray test on bunchy top. He sprayed KNF protectors at 1:1000 and KNF food at 1:500, at 25 gallons per acre. (Office Hours Ep. 87, 57:04) That is the full Master Cho rate for the bunchy-top banana treatment. (Office Hours Ep. 93, 34:56)
Results are early. In the November episode, the sprayed patch looked healthier and the spread had stopped. Drake said it was too early to call it proven. (Office Hours Ep. 100, 8:43) A month later, the leaves had shifted from light green to dark evergreen. Drake thought the spread had slowed, maybe reversing. (Office Hours Ep. 103, 10:23) The two episodes differ on whether spread stopped or only slowed.
The library does not name the protectors used or give the soil treatment formula. It also says nothing about plants that carry the virus without symptoms.
