The forecasting tool SOPRA has been developed with the objective to optimize timing of monitoring and control measures of insect pests in fruit orchards. Applying time-varying distributed delay approaches, phenology-models were developed driven by solar radiation, air temperature and soil temperature on hourly basis. Models are developed and validated for Dysaphis plantaginea, Hoplocampa testudinea, Cydia…

Four intensively managed permanent meadows were cut during several years either at seed maturity of the forage grass species or at heading stage. This last cutting regime prevented the self-reseeding of the forage grass species and brought about a deterioration of the botanical composition of the cocksfoot meadow and the foxtail meadow. The populations of…

Dans les cultures fruitières, vingt à trente opérations d’entretien doivent être effectuées chaque saison à l’aide de machines. Elles concernent par exemple le mulching ou la protection phytosanitaire. En vue de décharger le conducteur et d’automatiser totalement ou partiellement les différentes opérations, les systèmes de guidage automatique jouent un rôle-clé. Jusqu’à présent, il n’existait aucun…

Bacterial wilt caused by Xanthomonas translucens pv. graminis (Xtg) is a major disease of Italian ryegrass (L. multiflorum Lam.). Although targeted resistance breeding has resulted in cultivars with considerable levels of resistance, the mechanisms of inheritance of resistance are poorly understood and further breeding progress is difficult to obtain. In this study, molecular genetic diagnostic…

In 2004, collected ancient varieties of runner bean were investigated in a cooperative project between the organic seed nursery Zollinger, the university of applied sciences Waedenswil, and the Agroscope Changins-Waedenswil Research Station ACW. The principal aim of this project, which is part of a national action plan of Swiss Confederation, was to preserve and promote…
