Fungal Biodiversity on Runner Bean Growing in Two Systems of Plant Protection
MetadataShow full item record
The aim of the investigation was to evaluate three fungicides (Dithane NeoTec 75 WG, Sumilex 500 SC, Amistar 250SC) for their antifungal activity against fungi occurring on bean seeds using two types of nozzles: standard RS-MM 110 03 and injector type ID 120 03 C. Studies of three years (2007-2009) were conducted at Czesławice in the south-east of Poland. The objects of research were the plants and seeds of cultivar Blanka. The following agents were used for protection. Observations were carried out in October in each year. Diseased plants were collected for mycological analysis. Seeds with symptoms were noticed on the investigated plantations. The results of mycological analysis showed that bean plants were colonized by Fusarium spp., Sclerotinia spp. and Alternaria alternata. The best health status and the lowest number of colonies were noticed on plants protected by azoksystrobine with both types of nozzles.
