much TDZ do you want? I have never found it useful in Hosta TC, but it
does work well with Daylilies. I have never used it in the field. I
have one of those infamous 5 LB bags of DROPP, which for TC is a five-lifetime
supply. If you want a small amount to experiment with, I can send you
some. By the way, you can put TDZ into solution the same way you do BAP
(titrate it into solution with concentrated base). The powder just settles
out. The stuff is powerful, and it has a long residual action, so you may
get some unexpected results. With Hosta, it tends to break down
variegation chimeras, as it promotes adventitious buds.
means that you need twice as much (by weight) as BAP to get 1000 PPM. One
milligram per kilogram (1 liter is a kilogram of water) is one PPM, so 1
gram/liter (2 grams DROPP) is 1000 PPM. 0.44 mg/ml DROPP is
approximately 1 mM TDZ.

After reading the Journal HostaScience articles on
hosta propagation I am very interested in trying some experimenting with
Thidiazuron (TDZ) .
Beings that I live in cotton country, I found a local source
for DROPP produced by Aventis. Dropp cost about $62 a pound in 50% WP form
with a minimum purchase of 5 lbs.
I would like to share the cost with 4 other people if there is
an other interest. Please contact me directly if you are
If anyone could supply the dilutions formula to get a 1000 PPM
from the 50% WP, it would be appreciated.
