For a num-ber of diseases like powdery and downy mildew since long suitable control strat-egies are available. In contrast, diseases/ disease complexes like esca, phytoplasmoses and viruses are espe-cially problematic since they cannot be cured by chemical plant protection. The pathogens can be present in vines in a latent mode without showing any symp-toms but finally leading to losses in yield as well as quality and eventually result-ing in death of infested vines. Therefore, the BigGrape-project focuses on the analysis of these disease complexes. Since esca, phytoplasmoses and viruses can be transferred during grafting dis-semination with the young grafted vines cannot be excluded. Hence, early diag-nosis is particularly important for viticul-ture. The BigGrape-project aims are the de-velopment of pre-symptomatic and spe-cific detection methods of the endogen grapevine diseases esca, phyto-plasmoses and viruses. These methods serve as the basis for a regional monitor-ing of vineyards and the development of control strategies. Within the project a phenotyping pipeline for the early de-tection of these diseases shall be devel-oped using non-invasive air- and ground-based hyperspectral and multispectral analyses. Visual rating, PCR-based methods and chemical analyses are ap-plied to get reference data to be corre-lated with the data of the spectral anal-yses. This new and non-invasive method pro-vides the opportunity to optimize the monitoring of grapevine diseases in viti-culture and also the possibility of selec-tion for grapevine propagation and breeding. 42 Berichte aus dem Julius Kühn-Institut 186
