Building systems adapted to partially resistant varieties


The third Innovine annual meeting took place in Plovdiv - Bulgaria - from the 22nd until the 24th of February. ENTAV/IFV took advantage of the presence of about 50 researchers in the same place representing a large concentration of grey matter, to organize two brainstorming sessions. The first one on new technologies allowed to establish a complete list all the sensors and DSSs dedicated to viticulture available on the market. It also allowed to identify some viticultural or agricultural parameters that can still not be assessed in field by sensors (i.e. water deficit, N, P and K in soil and leaves). During the second workshop, three main issues specific to partially resistant varieties to powdery and downy mildews were identified: 1) Maintaining the durability of the resistance, 2) Managing secondary pests and diseases, 3) Enhancing the acceptance of these new varieties by winegrowers, consumers and policy makers. All the researchers agree with the fact that it will be necessary in order to avoid eroding the resistance and selecting heavy virulent strains of pathogens, to maintain a minimal level of spraying. These sprayings that shouldn’t exceed 2-3 treatments over the whole growing period will aim at reducing the pressure of pathogens. To position them optimally and accurately, DSS and epidemiologic models adapted to resistant cultivars will be very useful. The research works carried out by a PhD student supervised by Horta in the framework of Innovine are very promising with this regard.
