I know this thread is about a year old but me and my buddy have been using this stuff with great success. I had a fungi so bad, my clones wouldnt root and
Eagle 20 would not get rid of it. I could actually see the mycelium.
This only problem with Tebuconazole is that it will stunt the plant, turn them dark green almost black, the stems will turn red. The good news is that you can take cuts off the mom and they will root. You pretty much have to toss the moms but the clones will be fungi free. Then after that, the fungi will be so weak, that a follow up of
Eagle 20 will fix the problem permanently.
All in all Tebuconazole works great on Cannabis. I also helped another person that was having the same problem and it saved all his moms. He was using
Eagle 20 and it didnt work.
I believe there is an
Eagle 20 resistant fungi going around from contaminated clone onlys. I believe its responsible for the duding problem on most of the OG clones.
