The HLB comprehensive nematode action plan is a set of specific recommendations based on the analysis of all nematodes that effect potatoes, including potato cyst nematodes and free-living nematodes. The basis of this plan is a unique software program that not only takes account of the populations of harmful nematodes, but also key soil parameters such as pH, organic matter content and the tolerance of the potato cultivars. The result is a set of practical recommendations, with all the key data in a clear overview.
