Kapsa J. | Osowski J. | Bernat E.
The NegFry model used for timing the chemical control of potato late blight was validated in field trials at Bonin in the years 2001.02 (4 trials). In these trials the number of fungicide treatments recommended by NegFry was about 34.5 percent lower (on average) than the number of treatments in a routine spraying scheme. This reduction was mostly the results of a delay in the time of the initial fungicide application and longer spraying intervals recommended by NegFry.
