Assessment of pesticide content in agricultural soils of the South Moravian Region
Mádrová, Anna ; Mravcová, Ludmila (referee) ; Komendová, Renata (advisor)
This bachelor's thesis deals with the issue of pesticides in soil. It evaluates the concentration levels of pesticide residues in agricultural soils in the South Moravian Region in 2015-2021. Pesticide residues were monitored as a part of the Basal Soil Monitoring System, the concentrations were determined by liquid chromatography–mass spectrometry. The monitoring is performed by the Central Institute for Supervising and Testing in Agriculture (ÚKZÚZ), which also provided all the data for this work. The most frequently detected substances were selected for evaluation – 2-hydroxyatrazine, boscalid, diflufenican, dimoxystrobin, epoxiconazole, prochloraz, tebuconazole and terbutylazine-2-hydroxy. The highest concentration was measured for boscalid. Epoxyconazole was the most frequently detected substance. The concentrations of pesticide residues found in soils of the South Moravian Region are several times lower compared to the Zlín Region and the Vysočina Region.

Control of important pests in potato
VLKOVÁ, Vendula
This thesis is focused on the influence of the application of plant protection products in potato growing systems. The use of plant protection products is these days an important issue that needs to be further solved. Product requirements are constantly changing and tightening up. As with other crops, the protection of potato crops against harmful factors cannot be underestimated. In the literature review, this work deals with the description of harmful factors that may affect tuberous potato crops, methods of protection, the use of plant protection products, as well as the application of integrated protection procedures in potato growing systems. The main part of the work consists of monitoring the monitored potato stand, its comprehensive evaluation, description of the land, agricultural technology and methods of regulation of harmful factors on the monitored land. As part of the evaluation itself, the effectiveness of two insecticidal plant protection products against potato beetle, one biological product and one chemical product was compared and evaluated.

Influence of neonicotinoids on insect communities with focus on bees
Weingartová, Barbora ; Erban, Tomáš (advisor) ; Šípek, Petr (referee)
The bachelor thesis is focused on pesticides and their impact on the environment. Plant protection products must undergo a comprehensive assessment involving the impact on nontarget organisms. Negative effects of pesticides are not only assessed in humans and other vertebrates but also in invertebrates. Pollinators that play a vital role in ecosystems are an important group for evaluation. This thesis specializes in a group of pesticides called neonicotinoids, some of which are currently banned in some countries. This thesis mentions array of neonicotinoids, their toxicity and effects on pollinators that were observed. Reassessment is crucial in order to make a comprehensive picture of whether the ban was correct. . Keywords: pesticides, neonicotinoids, pollinators, honeybees, bumblebees, colony collapse disorder

Common agriculture policy (chosen aspects)
Zhoř, Radim ; Sato, Alexej (advisor) ; Polívka, František (referee)
This thesis deals with imports of parallel plant protection products for commercial use from member states of EU to Czech republic. Because these products are chemical based, trading with them is thus stricktly regulated and controlled. This thesis provides clear and comprehensible procedure for application for authorizing a parallel import and as such represents a practical guideline for a potencial dealer/importer with a theoretical insight of the problem.
