Improved Tree Health

Cambistat® has been shown in numerous scientific studies to have a positive impact on tree health in a number of different ways.

Increase Chlorophyll

Trees treated with Cambistat® exhibit glossier, darker green leaves that improve their appearance.*

Increased Chlorophyll

Chlorophyll increase on Red Oak

Improved Root Systems

Reducing vegetative shoot growth results in an increase in vital fibrous root densities.**

Improved Root Systems

Fibrous root improvements on Sugar Maple

Drought Tolerance

Studies have proven that drought tolerance of treated trees is improved by nearly 100%.*

Disease and Decay Reduction

Treated trees have shown in numerous studies to be significantly protected from diseases such as scab, anthracnose, cankers, root disease, and decline.

Disease and Decay

* Percival, “Paclobutrazol-induced Drought Tolerance in Containerized English and Evergreen Oak”, Arboriculture and Urban Forestry 33(6): November 2007

“Overall, recovery (PI, leaf chlorophyll content, necrosis, electrolyte leakage) rates of drought-damaged trees treated with PBZ ranged from 20% to 50% higher than non-PBZ-treated trees (Tables 5 and 6). In all cases, control trees (non-PBZtreated) had the least capacity for recovery.”

“In the case of English oak, PI values as a measure of leaf photosynthetic efficiency, Pn, and leaf chlorophyll content were all significantly (P < 0.05) higher than non-PBZ-treated controls"
