Don't know why, but have had zero crud this year on my heart varieties...Last year I had 6 or 7 types get medium bad crud before plant out...The first year I grew Ukranian Heart, I pulled the seedlings as I thought they were too close to the windows and getting burnt edges...then I just decided they must be sickly, so gave them the yank...I only planted 4 hearts this year, but they are all green tipped as they should be....Yasha Yugoslavian is the most incredible thick stemmed seedling...Hard to believe it is a heart...

I have never noticed it spread in my seed flats, where there is a lot of congestion at times.
