PLANT HEALTH
... continued from page 29
In the data shown in Figure 3
for scaevola 'Blue Fan' cuttings
six days after the cuttings were
sprayed. Cuttings were treated
with two rates of Advocate at two
different spray volumes one day
after cuttings were stuck.
(page 28), note that increasing the
spray volume for the applications
can increase the effect of the IBA.
This has been seen across research
trials where multiple spray volumes
were applied. On average, two to
four quarts/100 ft2
bench space
will be sufficient to treat freshly
stuck cuttings, but higher volumes
may be used depending on the
production system for each grower.
It is recommended that users test
rates and spray volumes in their
production systems on a small
number of plants before applying
to a larger number of plants.
When propagating harder-toroot
woody perennial species, and
depending on climatic conditions
at the time of rooting, one to two
additional applications of Advocate
may be required to achieve desired
rooting.

FOLLOW-UP APPLICATIONS
Applications of Crest can be
made to the plants once rooting is
established. This can be helpful with
plants that are slower to start and/
or when conditions favor slower
growth.
Figures 1 and 2 (page 28) are
from a grower trial conducted in
2020 on abelia 'Kaleidoscope'.
Abelia cuttings were sprayed at
the time of sticking with Advocate
at 1,000 ppm and again at 1,000
ppm 10 days later. Once rooting was
established, three sprenches of Crest
at 1.0 fl.oz./gal. were applied to the
abelia at two-week intervals. In the
pictures, the plants in both trays
were rooted using Advocate prior to
transplanting, but the tray on the left
in each picture received the three
applications of Crest.
These photos illustrate one
particular production scheme for the
woody perennial (abelia). The number
of applications for both Advocate
and Crest will vary by crop, growing
conditions and the production plan
employed by the grower.
