Název v původním jazyce

Population structure of Phytophthora infestans relating to mating types and fungicide resistance in 2003 ? 2006 and the efficacy of fungicides against potato late blight

Popis výsledku v původním jazyce

During 2003 ? 2006 potato and tomato plants with late blight symptoms were collected from various regions and localities of the Czech Republic. A total of 352 Phytophthora infestans isolates were collected and analysed for mating types and metalaxyl anddimethomorph sensitivity. Mating types were determined using the conventional pairing assay and CAPS technique and ratio of A1 to A2 mating type was recorded 68 % : 32 % for the benefit of A1 mating type. Almost all isolates were found metalaxyl and dimethomorph sensitive. Only 18 isolates from 2003 were resistant and four isolates from 2004 were intermediate to active substance metalaxyl. Simultaneously, exact field trials with the medium-early potato variety Ditta were established on experimental station PRI Havlíčkův Brod ? Valečov and studied the efficacy of fungicides against potato late blight. In 2003 no late blight occurred in the trials; however, tuber yields increased in majority of fungicides. The years 2004 ? 2006 were chara
