Serenade is the stuff- i have had bud rot this year- constant rain here - I lost over half my crop to rot in 3 days- got advice from a long time mountain grower- I cut all fan leaves to aid in air circulation- extreme you may think but not as much as BUD ROT- then sprayed with serenade- i was also able to drag 400 feet of power cord and put a fan on my plants-as it rains here there is no breeze- stagnant damp air a fungi paradise-I resprayed with serenade after each dowwnpour- I was remoning buckets of rotted bud each day and in 3 days of serenade treatment I had stopped the growth- Rhizome suggested serenade to me 3 yeras ago- It works
