| Blackrot is een schimmelaantas- ting bij appels die recent in Nederland ontdekt is en afkomstig lijkt uit zuidelijker landen. De schimmel overwintert onder meer op vruchtmummies en komt dan ook vooral voor op appelrassen die hun mummies lang vasthouden zoals Elstar. In een driejarig onderzoek is het effect van het ver- wijderen van de mummies als infectiebron op de aantasting bestudeerd. De resultaten zijn veelbelovend: Zo’n 60-90 procent afname van het aantal aangetaste appels bij de oogst. |

| 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... |

| In this report a summary is given from several experiments during three years at four farms. This summary focuses on yield; mineral balances and product quality are sometimes described. The overall soil quality descriptions can only be found in the complete reports which can be found in the reference list. This project aimed at reduced manure applications in an adapted fertilization strategy in several farm types, realizing: • Equal or higher yields • Improvement of product quality • Maintenance or improvement of sustainable soil fertility. The results of the experiments at four farms are: • At Joost van Strien’s farm it has been shown clear that the use of cut-and-carry fertilizers is a good option. The fertilizing value is as good as or better... |
