I hate to burst Donna’s impression of the Bulb and Stem nematodes but I would venture a fairly large sum of money that she already has them on her property:-(( Follow the link below and then go to page 423 to start reading about Bulb and Stem Nematodes. On page 424 you will read that these are REALLY widespread worldwide and they infest more than 500 species of plants and fungi.
Notice that they sometimes infest commercial mushrooms and the compost sold when they change out the mushroom beds.
Bulb and Stem nematodes are a serious pest in rye grasses and fescues in Canada. Onions and garlic skins that you add to your home compost can contain the bulb and stem nematode. As will MANY different plant tissue.
IF you have EVER bought bedding plants and or landscape plants odds are that they contained some Bulb and Stem nematodes….
These nematodes are probably a LOT more widespread in local and state daffodil bulb swaps than anyone cares to mention!
Again if you have EVER walked in a botanical garden, came home and walked in your yard without disinfecting your shoes then you probably have them. Keith Kridler

    I think my nematodes came from mushroom compost. Several of us in southwest Ohio have had problems of one sort of another after using it. Obviously, we don’t anymore!

    I had serious problems with commercial mushroom compost. Lost entire plantings in  newly made beds. I spoke once with the main hort. guy at a large botanic garden here and he said that whenever they received soil for new beds, they let it sit in a paved area while samples went for testing. Sometimes the result was so negative that the soil would not support plant life of any kind. So they let it bake in the sun on concrete for well over a year and tested again before using.

    Ok, Keith,
    So if I do have some, I don’t have them badly enough to cause symptoms or ruin bulbs, right?  I have never observed bulbs that have those alternate rings of rot in the bulbs.  I have never seen the pinkish fuzz that is the dried nematodes on bulbs.  So, if you are right, and I have them, I should have occasionally observed those symptoms or had loss from them.  Seems that nature has a way of controlling the bad stuff so that it doesn’t get out of hand.  So since that seems to be the case here, I still think I will concentrate on the fly and fungus.  However, thanks for the “good” news, Keith.
