The model, called Plasmo (Plasmopora Simulation Model), simulates grapevine downy mildew
biological cycle on the basis of agrometeorological parameter, allowing the best timing for
fungicide treatments. The model reliability was evaluated during several years of research,
comparing the results obtained by applying traditional methods of crop management with those
planned according to model simulation.
