Abstract

Changes in populations of Phytophthora infestans influenced earlier appearance of the disease. The late blight monitoring system enables evaluation of reliability of the forecast part in the decision systems of potato protection against late blight and, at the same time, serves as a safeguard for practice if a new, earlier infection source appears. The first step in building of Polish late blight monitoring system, approachable in Internet, was observation carried out by workers of Plant Protection Inspectorate in Lublin voivodship as a part of Polish-Danish research project “Development of an Internet based DSS for Cereal Diseases and Potato Late Blight in Poland, 2001–2002”. The results show that it was possible to find early infections as primary attacks (spots on leaves). In most cases the attacks were initially found on susceptible varieties (74%). The growth stage at first attacks was higher than 37 (BBCH), indicating that very early attacks caused by oospores from the soil was not a widespread problem in the Lublin voivodship.
