Action Codes

Take the letter in the Action Code column and correspond it with the action that is to be taken.
ie: since the letter in the column is "C", it would correspond with Action 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 References page to find the corresponding Nema Note.
Ex: Below Nema Note 9 is referenced, so on the Useful References page, find Nema Note 9. You can select "print" to view the larger PDF and/ or print it off.

"S" and "H" Columns
Each pair of columns resides below the species of nematode found in the assay.
Column S = # nematodes per 500 cc soil
Column H = # hazard index for crop.

Nematode Counts & Hazard Index (potential crop damage)
The value in the “H” column is an index of potential harm by the nematode species to the crop listed on the same line:
Hazard index:
0-19 Very Low
20-39 Low
40-59 Moderate
60-79 High
80-100 Very High
So what does this mean?
