Ditto. Also, the NW maples on peninsular Halifax  exhibiting spectacular go=
lden-yellow coloration just before leaf-drop.

Hi Steve,

I meant to reply to you earlier.  I too noticed the scarcity of tar spot fu=
ngus on the Norway Maples this year, on my daily walks from home in central=
 Halifax to work in south end Halifax.  I took careful note this afternoon,=
 when I spent several hours raking leaves, and probably less than 10% had t=
he spot, when in other years nearly all would have been affected.

Cheers,

Patricia L. Chalmers
Halifax

&gt; We have a couple of these NMs at opposite edges of the garden. They ar=
e still fully leafed (though most leaves are yellow by now) and always lose=
 their leaves later than the other maples here. In other years every NM lea=
f by now would have a black fungal

&gt; <br>
&gt; For the first time in memory, none of the leaves this year are spotted=
. Have others elsewhere seen this lack of sustained infection in 2018? Coul=
d it be attributed to the unusually long, hot, bright summer suppressing th=
