Sampling Tools and Precautions

Soil (and roots) can be sampled with any simple container such as a food can, a shovel, or special corers. Notes: When sampling to advise farmers on the presence/absence of plant parasitic nematodes, make sure the sampling tools are cleaned and disinfected after every soil sample. Always store the soil samples in plastic bags (in paper bags the soil will dry out), and keep them away from the sun (heat kills nematodes!). Handle the samples carefully: throwing them around, or any other mechanical violence (soil sieving, mixing), will kill nematodes as well. The sooner the samples are extracted, the better. For reliable results, the maximum storage time, at 4°C, is 1 week only.
