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.*

Chlorophyll increase on Red Oak
Improved Root Systems
Reducing vegetative shoot growth results in an increase in vital fibrous root densities.**

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.

“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"
