7. Pests of non-cereal crops

To develop methods for the containment of soil dwelling nematodes by the integrated use of crop rotations, reliable resistant cultivars and efficiently-used, safely-formulated nematicides, thereby delaying selection of virulent nematode pathotypes and minimising cost and risks to operatives and the environment. Particular attention is paid to potato cyst nematodes and to other nematodes of forage and grain legumes. Problems of nematode attack in oilseed rape and other alternative crops such as sunflower and lupin are being investigated. Studies on the nature of host tolerance to nematode attack and the complex interactions between nematode host races and culture resistance are contributing to the development of integrated control measures.
