Field surveys were performed in winter and spring rape crops of agricultural companies and individual farmers during the period of 2001–2003. A questionnaire was completed for each experimental field, giving a description of the crop. The incidence and severity of fungal diseases were estimated annually in 14–18 winter and spring rape crops. Seed samples were taken from each field and composition fungal communities on harvested seed was estimated. Alternaria blight and Phoma stem canker were present on stems of all investigated winter and spring rape cultivars and Alternaria blight occurred on siliques in all experimental years. In 2001, most favourable year for spread of diseases, Alternaria blight damaged 87.2 100% of winter rape and 100% of spring rape siliques, maximum disease severity was 6.66 and 7.24%, respectively. All cultivars of winter and spring rape were susceptible to Alternaria blight. Phoma stem canker was more often found on stems of spring oilseed rape – up to 98% of stems with symptoms of Phoma stem canker. Seed fungal infection level was 10.0–100% in winter rape and 16.0–93.6% in spring rape seed samples. The most frequent fungi on seeds of winter and spring oilseed rape were Alternaria spp. and Cladosporium spp.

In his voluminous memoirs compiled in the early 17th century the Dominican Martin Gruneweg describes a pageant named the Parade of the Planets that took place in Warsaw on 15 February 1580. Central to its stage design was the iconography of the seven planets, each of them represented by its Zodiac sign and its affiliated House. However, no less important for the spectacle was the appearance of numerous characters and stage props from the carnival tradition, e.g. richly dressed men from the Orient, Bacchus, a procession of floats. The Parade of the Planets was a festivity which brought together the court and the townsfolk; it was probably organized by both court and town. More generally, it could be described as an urban carnival parade mimicking some features of the Renaissance Trionfo. The knowledge of celestial phenomena presented in this spectacle was probably adjusted to the needs of a wide audience of the ‘middling sort of people’, whose belief in the geocentric model of the cosmos was still intact. It seems that the Parade of the Planets contained hardly any profound insights or hermetic clues. Gruneweg, though, does find it susceptible to an allegorical interpretation which reveals the spectacle's embedding in Christian spirituality and middle-class virtues. He is pleased with the colourful spectacle, but warns of taking too much pleasure in this kind of entertainment.
