| Abstract: | Summary Growers are being faced with a conflic between the effects of specialization on increasing pest and disease problems (particularly late blight, Colorado beetle, cyst nematodes and tuber moth), and public opinion that will force them to reduce the use of pesticides. For this disease and these pests international research programmes are needed to develop parental lines and cultivars with durable resistance that can be used world-wide. This account is based on ‘The potato in world perspective’, a paper read at the First World Potato Congress held on 8–10 July 1993 in Charlottetown, Prince Edward Island, Canada. |
