Zhodnocení výskytu mandelinky bramborové a účinnosti insekticidů v porostu brambor na lokalitě v Žabčicích

Kreuzová, Sandra January 2018 (has links)
This thesis deals with the effectiveness of insecticides on Colorado potato beetle, which is one of the most serious pests that damages the above-ground part of the potato crop. Field trials were established in the years 2015-2017 at the campus of the Mendel University School in Žabčice. Insecticides from the group of neonicotinoids (Actara 25 WG, Biscaya 240 OD, Mospilan 20 SP and Monceren G) were used here. Insecticides from the group of pyrethroids (Vaztak Active, Nurelle D, Karate se Zeon 5 SC) and diamides (Coragen 20 SC) were used. Last but not least, two insecticides (NeemAzal T / S, SpinTor) have been applied that are useful in organic farming. In 2015 and 2017, the presence of Colorado potato beetle was evaluated before and after application of individual insecticides. Based on the occurrence of potato beetle larvae, efficiency was calculated. In addition, the difference between insecticides and insecticides and control was statistically evaluated. The year 2016 was not evaluated because of the low number of potato beetles.
