Statistical Significance
„
„
No differences in the number of
phylloclades with buds across rates.
Mean = 125 phylloclades with buds.
Statistical Significance
„
Statistical significance occurred for the
chemical x concentration interaction:
„
„
Number of buds per pot (P<0.017, r2 = 0.79)
Number of buds per phylloclade (P<0.006, r2 =

Conclusions
„
Bud count and number of buds per
phllyoclade increased with increasing
Configure concentrations of 400 ppm.
„
„
Bud count on some phylloclades exceeded 12
buds with >200 ppm Configure.
Spray coverage is important.
„
Bud count was higher at the top of the plant than on
phylloclades which were covered.

Conclusions
„
Configure concentrations of >100 ppm
improved the number of buds per
phylloclade.

Overall Thoughts
„
„
The use of Configure will improve the flower
power of Christmas cacti.
In addition, early sprays of Configure can
have a positive effect on branching.
