I was out today with a spray bottle of diluted ammonia, spraying slugs, and was wondering if ammonia had any effect on nematodes?

Are there people who regularly spray hostas with ammonia that also have nematodes in those plants?

Yes, Narda, Some still sell Cygon. I get mine from Garden South, a wholesale
supplier of garden stuff. Most gardeners have trouble getting it because
many retailers have stopped carrying it. I suggest you use another systemic
such as Orthene or Isotox, they work too but not as fast and well. All of
these later applications are for "stragglers" that still show up after you
have gone through the previous stages. Systemic rose care (It is inexpensive
and easy to get) is a key in this and must be applied very early, just when
the worms start becoming active. Most of the chemicals applied by
professionals are available to registered applicators only (like Vidate). If
you have fish in a pond, birds, or pets running around, be careful any time
you use strong chemicals. I repeat rose care application every 2-3 weeks (2
if it rains a lot) until the clumps are fully expanded, then follow up with
a systemic spray. When a clump shows still infected, removing all the leaves
down to the ground will usually get most of the worms that are in the
leaves. Disinfect the knife in Chlorox after each use and discard the leaves
using a plastic bag. Most clumps resprout after this. In late autumn make
certain you apply Peroxide or Terrachlor to kill any worms left in the
ground. Like I said, all of this is complicated and releases poisons so I do
this only to valuable hostas, any cheap stuff gets dug and thrown out. Use
the saucer treatment for absolutely irreplaceable hostas. I do that in a
screened part of my shade house to keep the birds or pets from drinking the
poisoned water. Be careful, all mentioned are potent chemicals that should
be used per the instructions and with appropriate forethought, care and
precautions and as little as possible. George

George, can Cygon still be purchased?
