Pinon Pine Pitch Mass Borer

Asked April 20, 2020, 7:53 PM EDT

I have 6 pinon pine all which have various levels of attack with pitch mass borer; one is much worse than the others. My neighbor recommended "Viper" by Martin's - it is a cypermethrin. They have used it for past 3 years with some success. My question is: 1) is this OK to use, 2) what are best times of year and 3) frequency, 4) amount of spraying.

This weekend, I tried to scrape the sap away and find a bore hole and stick a sharp object into it. Today I sprayed the trunks of the trees and branches. I live at 6500" in Albuquerque, NM.
