Simulation models describing potato early blight development, potato contribution to disease suppression. This timing was consistent regardless late blight development, and chlorothalonil dynamics were used in of the inoculation date or the susceptibility group of the cultivar. For analyzing the effect of fungicide applications on disease epidemics. The potato late blight, sprays applied at orjust after the date of inoculation were early blight model previously had received less validation than the other important for suppressing the disease. The date at which sprays can be models and therefore was validated by independent sets of data (12 safely terminated (date of the last application) was similar for both diseases: epidemics that had developed in susceptible and moderately resistant approximately 3 wk before vine kill. Based on these results, we developed a cultivars over 2 yr). The early blight model and the previously validated late fungicide use strategy with the goal of reducing the number of sprays while blight model were used to evaluate the contribution of each fungicide maintaining a low risk of severe disease caused by either pathogen. Our application in a weekly application schedule (common grower practice) results indicated that using the proposed strategy may save two to four relative to overall foliar disease suppression. For early blight, applications sprays in the northeastern United States without increasing risks from beginning at 6-7 wk after planting were the first to make a positive inadequate control.
