| In organic potato production yields are often reduced by potato late blight (Phytophthora infestans). Two aspects are important in late blight management: a sufficiently high (field) resistance to late blight, and early tuber formation. With early tuber formation the period of tuber growth is extended at the beginning, and with a high resistance level at the end. In 2006 and 2007 experiments were carried out in which the effects of the physiological age of seed tubers on field resistance to late blight and on tuber yield of potatoes (Solanum tuberosum L.) were tested for early and moderately late varieties. The results indicate that with the use of physiologically older seed tubers (by pre-sprouting) the field resistance to late blight is generally lower... |
