white substance on 3 yr old white pine

Asked June 24, 2019, 2:25 PM EDT

We planted 20 white pine from the local extension office. A few of them have some sort of white substance sporatically on them. Not sure if bug or mold etc. What might it be & how do we proactively treat them. They look super healthy otherwise. tks
