sorry, i have no experience growing nematodes
other than what have shown up in terrariums. :)
nematodes are always around. i think you're
fine once you get an area innoculated. short
of major interruption in the soil (severe
drought, salt-water flooding, some other kind
of poison or sterilizing event) i doubt you
will need to worry about it again.
the basic idea of biological control is to
accept some losses because you need the
target species around to feed the predatory
keep growing the succeptible plants and some
of those will have some root knot nematode action
(even if you can't see it) and that will keep the
i don't think you'll need any thing more fancy
let me rephrase. you want to supply a food source for the
root knot nematodes so they can be prey for the predatory
nematodes, so simply put, grow the plants you've already
been growing that are succeptible to the root knot nematodes...
i don't think you need to get any more fancy than this.
which might appeal to your idea of simplicity and lack of
planning and further benefit of low budget.
if you really do want to get more fancy that would
involve growing root knot succeptible plants in
sterile soil and innoculating them with root knot
nematodes. then you'd have your source of food for
peace and happy TG,
i'd also put them on the surrounding pathways and lawn
and ask the neighbors if they wanted any. as someday
perhaps they'll want to exchange plants.
the medium they are sent on may be dry and
divisible and so could be cut up and used as
needed. the dry media probably has a shelf
life of a year or more.
if instead they are sending live critters
then all bets are off for how long they
can be stored or relied upon, but there is
a good chance that if left to dry out they
will make cysts or lay eggs or whatever this
species does when conditions get unfavorable.
then you can store those for a period of
time and break them out when needed...
i'm glad to hear things have improved from
such a simple change. i'll keep hoping that
it will be sustainable. i think it will be
especially considering you keep your gardens
going and there isn't much fallow time.
i'll always be interested to hear how it
the sad thing i'm finding whenever i try
to get decent and suitable information on
any plant or critter is that the books at
the library don't have much depth (they are
written for the popular audience not the
researcher). often i have to wait a bit for
the universities to release a textbook and often
those are not full of the information i'm after
either as they are written from the perspective
of whoever is doing current research to suit
some industry sponsor or ...
actual, in depth, basic knowledge is very
hard to come by. distilling the parts from
several textbooks often gets me close, but
i still feel there is so much of a gap at
times even then (besides the fact that my
brain does not hold some information well
at all (scientific names, formulas and
certain abstractions)). i do much better
with procedural information and ...
if i get a chance i'll read up on nematodes
and see if i can figure out what you are
after. i have all winter and an empty reading
