Soil and crop samples are processed using the tried and tested incubation method and then scrutinised under a microscope for all the major parasitic nematodes (including Meloidogyne spp., Pratylenchus spp. and Paratrichodorus pachydermus) and if desired the trophic nematodes too. HLB has PCR tests for all the major nematode varieties and you can be sure of practical advice on the basis of the analysis results. HLB can also provide a comprehensive nematode action plan, which comprises a complete package of recommendations based on analysis of potato cyst nematodes, known cultivar tolerances and soil pH and inorganic matter content.
