Nematologist's Comment

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?
