Planting is well under way and by the time this is read many will have finished.
We are all aware of the need to manage potato cyst nematode (PCN) in an integrated manner and not just rely on nematicides. Rotation length is one of the keys – moving from a four-year to an eight-year interval – has had a huge influence on PCN populations. However, this has not been easy for any grower to manage when accessing additional new and suitable potato land.
Resistant varieties, such as Eurostar and Arsenal, are doing a great job too and market acceptance of these newer varieties is increasing.
It is important all growers need to control potato volunteers, to allow the benefits of these lengthened crop rotation strategies to be fully realised.
