"A PHC technician also will consider your expectations when deciding how to implement a
PHC treatment program." explains Gerstenberger. One important question is just when do you,
the client, want to resort to chemical control of pest problems. Some clients will tolerate a
greater percentage of plant damage before requiring action. Some clients will tolerate very little
plant damage. Often a client will tolerate less damaged on a prized ornamental specimen tree located
in the front yard as opposed to a group of shade trees growing in the back yard. This required the PHC
technician to apply a higher action threshold to some trees and/or sections of the landscape than others.
"Here, communication and understanding between the client and plant health care technician are key!"
Treatment recommendations are then made to the client based on that client's expectations.
The key to a successful plant health care program is communication between the client and PHC technician.
