Nematodes cause roots to become knotted and galled and impair the root system so that water and nutrients cannot be taken up. Nematode damaged plants become stunted, turn yellow and wilt in hot weather.
The best time to determine if you have a nematode problem is in the summer and fall, when nematodes are most numerous.

Deliver the specimen fresh to the county Extension Office. Plant samples may not be identifiable if they have been crushed, decayed or dried and shriveled.
To assist in obtaining a rapid, accurate identification of plant specimens, bring the completed Plant Pathology Form with the sample. You will need the following information:
- Description of site where plant was collected. (Sun/shade, natural area/landscape, wet/dry area etc.)
- Your name and address.
- Date it was collected.
- Description of plant (size, shape, description of flowers, etc.).
- Stage of growth: seedling, blooming, fruiting.
Proper diagnosis is necessary to achieve good pest management. It's important to remember that only a small percentage of insects on plants are pests.
