Don't spray if no sign of PC???
Literally no sign of them. I wondered if last year's total freeze out would crash the population, and it appears it has.
We are at the point here that iris are blooming and lilac blooms are browning out, oak leaves are basically fully expanded.
I have looked at hundreds to thousands of fruit on all species, and so far have seen one scar.
So, are they gone for this year? Should I spray imidan and triazicide anyway, or just hold off?
