If you Know
you are Submitting a Nematode Sample
|
- The
sample to be submitted should
contain all parts of the plant
when possible.
- Wrap
the sample in a paper bag and
package it in a sturdy box.
- Try
to mail the sample as quickly as
possible.
- If
the sample can not be mailed
immediately, keep it refrigerated

- It
is important that you try to
collect the sample prior to any
pesticide applications. Once
pesticides have been applied it
may be difficult to obtain an
accurate diagnoses.
- It
is helpful if the sample is taken
from an area that has early
symptoms of the problem. Areas
that are completely dead often
contain a number of secondary
organisms that may hinder the
detection of the primary pathogen.
|
- The
best time of year for nematode
analyses is during the active
growing season.
- A
minimum of 6 soil subsamples,
approximately 1" in diameter
and 4" in depth, should be
collected from an area that is
approximately one acre in size.
- The
sub-samples should be collected
randomly throughout the area.
- The
subsamples should be mixed
together thoroughly and about a
pint of soil transferred to a
plastic bag.
- Samples
should be shipped as soon as
possible.
|
Mail the sample as
quickly as possible! If the sample can not be
mailed immediately, keep it refrigerated or out
of direct sunlight.
