Addressing the Gaps in our Knowledge of Grapevine Downy Mildew for Improved Forecasting and Management

Fig. 3. Decline of lesion productivity with successive sporulation events. Individual lesions were induced to sporulate at intervals over time, and sporangia were collected and counted. For each lesion, the maximum sporangial production was set to 100 and all other sporulation events were scaled to the maximum to give relative sporangial production.
