Vlnatka krvavá (Eriosoma lanigerum), význam a možnosti její regulace
Klimešová, Lada
The research was performed in vegetation season of year 2014 in apple orchard near Nosislav in Břeclav district. The task was to compare efficiency of two auxiliary preparations and two insecticides, separately or in different combinations. Valuation of efficiency of these preparations in various variants was performed by measuring lengths of colonies of woolly aphid 1.2 and 7 days after application. The trial had been started at 4.6.2014. The most efficient variant was Cocana 1.5% followed by Mospilan 20 SP 0.013% -- Mospilan was applied immediately after applying of Cocana (efficiency 80.2%). Very good results were noticed on variants Mospilan 20 0.013% (efficiency 75.6%), Cocana 2% + Mospilan 20 SP 0,013 % -- tankmix (74.2%), Cocana 2% followed by Mospilan 20 SP 0,013% (68.8%), Cocana 1% followed by Mospilan 20 SP 1% (64.5%). Low efficiency was found out at Cocana 2% followed by Wetcit 0.3% (48.7%). The worst efficiency was by application of Cocana 2% followed by Spintor 0.6 l/ha (13%).

Amelioration of orchid germination in restored grasslands
KLIMEŠOVÁ, Lada
Amelioration of orchid seed sown with fungal inoculum was tested in in situ experiment in White Carpathian Mountains. The thesis evaluated reintroduction potential of four meadow orchids (Orchis mascula, Anacamptis pyramidalis, Platanthera bifolia and Gymnadenia conopsea) to restored grasslands.
