Below is a brief summary of all the general test that we do for growers. Click

here to get a price on the Testing Costs page.
Germination
A test that determines the plant producing potential of a seed sample under
ideal conditions. Results are reported on a percentage basis.
Purity
An analysis that determines the number or percentage by weight of contaminants
(weeds or other crop types) in a seed sample. This test does not determine crop
variety.
% Pure Seed
An analysis that determines the percentage by weight of actual seed compared to
other crop seeds, weeds or inert matter. This test does not identify the weed
seeds present. The pure seed test is a required test for all grasses. This test
is also a required test for all exports under ISTA and AOSA rules.
Vigor
A test that examines the plant producing potential of a seed sample under
stress conditions. This test, while useful in planning your seeding operations,
should not be used in place of a germination test.
1000 Kernel Weight
A test to determine the weight of 1000 kernels of the sample. This test
provides useful information especially for peas and lentils in determining the
amount of seed to plant on a per acre basis. Click here

Special Purity
a test for uncleaned canola and mustard where we will check for and count the
cleavers, wild mustard, and other brassica crops. Other weed and crop seeds
will be listed, but not counted.
Treated Seed Purity
A seed wash and separation of treated canola seed for the purpose of doing a
purity test on it.
Seed Treatment
We will treat your seed sample with the seed treatment of your choice in an
attempt to improve poor germination due to disease pressure.
Tetrazoleum Test
A one-day test to examine the plant producing potential of a seed sample (not
for official germination).
Green Foxtail
Resistance checked against Group 3 herbicides.
Kochia
Resistance checked against Group 2 herbicides.
Malting Barley Germ
A test to determine the potential of a lot of barley to make malt (a minimum of
95% is expected by the maltsters). This test is very different than that of a
seed germination and cannot be interchanged.
Herbicide Tolerance
A test to determine if a plant will be susceptible to a certain herbicide.
Soil Tests
Used when testing a germination of a cereal crop that has been sprayed with a
pre-harvest application of glyphosate.
