Abstract: In the UK, the most problematic pests of the potato crop are the potato cyst nematodes (PCN) Globodera pallida and G. rostochiensis. Populations of G. rostochiensis can be managed by the integrated use of nematicides (granular and fumigant), crop rotation and resistant cultivars. A field experiment was done to compare the use of the resistant cultivar Santé with 1,3-dichloropropene and the granular nematicide oxamyl at full and half-rates on an experimental site containing both species of PCN (mainly G. rostochiensis) at an initial population density of 189 eggs g^-1 of soil. Root invasion studies showed significantly different levels of invasion between cultivars and between fumigation treatments. Nematode multiplication was significantly decreased with Santé compared to the susceptible variety Estima. 1,3-dichloropropene and oxamyl significantly increased speed of crop emergence and percentage ground cover. The combination of Santé, 1,3-dichloropropene and oxamyl at full-rate was the highest yielding treatment. In addition, the use of 1,3-dichloropropene increased the overall number of tubers and improved the tuber size distribution. The results of the experiment show that an integrated approach to nematode control on heavily infested sites can lead to significant decreases in nematode population levels and give economic yield benefits.
