Cambistat®
Growth Reduction
Different Species Respond Differently
Every tree species has a different response to Cambistat. For instance,
the amount of active ingredient needed to treat a Sweetgum is 1/4th
the amount that is needed to treat a Bradford pear. We have developed
a rate chart that is used when applying Cambistat. Not all trees that
you want to treat are on this Cambistat
rate chart. We are in the process of developing rates for many
of the trees not currently listed and should have more information
on these in 2004 & 2005. We would welcome your partnership in developing
rates or feedback on our current rates.
Certain Trees Have a Reduced Response to Cambistat
These trees include Cottonwood, Poplar (Aspen), Ash, and Sycamore.
While you can treat these trees, growth response may be limited.
Most pine tree species also appear to have limited response to Cambistat.
More research is needed and we are developing rates to distinguish
between many pine, spruce and fir species that are common on properties
that you are maintaining. At this time, for most pine, spruce and
fir species use the F rate as listed on the Cambistat rate chart.

Practical Uses for Growth Reduction
Reducing the growth rate of trees has many practical applications.
It also has some very positive physiological affects. Research has
shown that slower growing trees have an increased
ability to withstand stress, increased longevity, and a reduced
need for resources such as nutrients and water.
 In
the landscape, there are many situations where reducing the growth
rate is very practical.
These include:
- Blocked scenic views
- Trees close to buildings
- Trees growing near power lines
- Landscape crowding
- Limited growing space for trees getting
large
- High maintenance trees such as bradford
pears
- Trees growing in patios
- Trees growing on boulevards, in sidewalks
or near parking lots
