Service Provided

The diagnostic lab will process soil samples in our usual manner and provide our usual report detailing the type and quantity of all plant parasitic nematodes found in the soil. Identification will only be to genus level (i.e. renifom (Rotylenchulus sp.) or root-knot (Meloidogyne sp.)).
