Very Limited Anecdotal Evidence/Coincidence, but...
The technical director at Kelpak in South Africa told me he was experimenting with spraying flower buds to see if it made any difference. With my very limited collection of plants these days, I don't have a lot of "Guinea pigs", but a Phrag. Lucky Girl "volunteered". I've had the plant a couple of years now, after receiving it as a gift from another grower. Like some phrags, it has a penchant for dropping one blossom shortly after a new one opens. With one blossom fully opened, and a bud close to opening, I sprayed the top 6" of the spike with a 1:250 solution, hoping to see if the next blossom looked any different.
The answer appears to be "no", but I'm now twenty days into the first blossom, and it is still hanging in there.
I know that this might be pure coincidence, but I'm throwing this out there in case anyone wishes to experiment.
