Nematologist's Comments
The nematologist will make comments based on the test results. On the report, you can find the comments in the area that is outlined in red.
Action Codes
For each sample, note the letter in the Action Code column to determine the action that is being recommended.
For example, since the letter in the column for the first sample is "C," the recommended action is C: Chemical treatment recommended.
A. No expected harm to crop production
B. Possible damage; consider chemical treatment
C. Chemical treatment recommended
D. Use of nematode-resistant variety recommended
E. Rotate with nonhost crop(s)
Nema Notes (if present)
Contain information about nematodes detected in the assay as well as management options.
If there is a number listed in the Nema Notes column, go to the Useful Reference page to find the corresponding Nema Note.
Nematode Counts in the "S" and "R" Columns
A pair of columns is found below each species of nematode found in the assay.
Column S = # nematodes per 500 cc soil
Column R = # of nematodes per gram of root
Asterisks after count numbers indicate a potential problem.
* Indicates low hazard. Nematodes are stressing plants, but factors such as
disease or moisture stress are probably also present.
** Indicates high hazard. Nematodes are likely to be damaging plants
severely even in the absence of other stress factors.
So, what does this mean?
In the example given above, multiple types of nematodes were found (CystSoyb, Lesion, Ring, RootKnot, etc...) in Sample ID 8G.
The two asterisks next to the numbers in multiple S and R columns indicate a high hazard. Nematodes are likely to be the cause of the damage.
The Action Code is "C"- which means "Chemical treatment recommended."
No Nema Notes were referenced.
