During large-scale surveys for soilborne Phytophthora species in forests and semi-natural stands and nurseries in Europe during the last decade, homothallic Phytophthora isolates with paragynous antheridia, semipapillate persistent sporangia and a growth optimum around 25 °C which did not form catenulate hyphal swellings, were recovered from 39 host species in 16 families. Based on their morphological and physiological characters and the similarity of their ITS DNA sequences with P. citricola as designated on GenBank, these isolates were routinely identified as P. citricola. In this study DNA sequence data from the internal transcribed spacer regions (ITS1 and ITS2) and 5.8S gene of the rRNA operon, the mitochondrial cox1 and β-tubulin genes were used in... |

The objective of this study was to evaluate the effectiveness of foliar application of various synthetic compounds and biological extracts against powdery mildew on wheat. Seed coats of winter wheat were treated by synthetical compounds (benzothiadiazole, salicylic acid, and glycine betaine) or by the extracts from plants (oak, giant knotweed, curcuma, and ginger). Then the seeds were planted using small-field experiments with powdery mildew infection (repetitions over a two-year period; experimental field in Ruzyne, Prague). Leaf area infection was measured and the Cumulative Proportion of Leaf Area Diseased (CPLAD) was calculated. Data were analysed using ANOVA (Tukey test, p≤0.05). Effectiveness of preparations varied 30 % to 72 % in 2008, and 25 % to... |
