The main pest problem is that of aphids transmitting BYDV Oats are the most susceptible crop. An insecticidal seed dressing should be used, or treat with an aphicide in late October. The cereal cyst nematode is encouraged by close cropping...

Potatoes can be taken at various stages, but usrratly after cereals. To corrtrol cyst nematodes (PCN), maincrops shorrld not be grown more often than two years in eight, seed crops one year in five to seven years, but earlies may be grown continuously if lifted before the nematodes develop viable cysts (i.e. before 21 June). There is some varietal tolerance of PCN species.
