juniper leaf blight

Post  dick benbow on Tue Jul 10, 2012 11:19 pm

here in the pacific NW we have had a lingering cold rainy spring into summer. The other day we went from 60's to almost 90 and then a week or so of sweltering heat. It didn't take long before the tips of my junipers especially
the natives began to show yellow tips.
been spraying a copper based spray. my teacher says to vary between brands, not to use same brand or ingredients continually. My rocky mountain junipers really affected.

Hello Dick,

Do you have any pictures we can see?

Thanks,

I'm sorry, I don't. As soon as I noticed it coming on, I removed the yellowing tips with a tweezer and then sprayed. So far, no new yellow tips but after initial spray in two weeks there is another chance for the spores
to spread again, so I plan to spray again rather than get caught again.

I did spray all my juniper but my shimpaku showed no sign, while the Rocky MT junipers was most affected.
