Abstract
In the years 2000–2003 influence of meteorological conditions in potato growing season on the efficacy of certain fungicides in controlling late blight was assessed. The experiments were carried out in two locations: Bonin (northern Poland) and Stare Olesno (south-western Poland). Chemical protection resulted in a longer time needed for yield gathering. Moreover, it had the positive effect on the yield. The highest yields were obtained both in Bonin and Stare Olesno in the year 2000. The efficacy of the fungicides was high (above 90%), irrespective of the mode of action in the plant.
