Everything is late-late-late this year, but soon our pine shoots (candles) will be expanding. Pine tip blight is most likely to infect newly-emerging shoots. Dothistroma comes a little later and infects needles. With pine wilt, what we see now is pines that were infected last year and are dead by now. (We need to get those chopped down and chipped/burned ASAP).
Here’s the link to some pine tip blight info in last year’s summary
And, of course, don’t forget about PINE WILT. Get those pine wilt trees cut down by May 1 at the latest.
