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.

The aim of the work was to verify the efficacy of the biopesticide based on entomopathogenic fungus Isaria fumosorosea (WIZE) Brown & Smith against Colorado potato beetle, Leptinotarsa decemlineata Say). A small-scale experiment with three varieties of potatoes was carried out on selected site. In addition to monitoring of the effect of the fungus application on the occurrence of the pest and plant damage, yield of cultivated varieties was evaluated at the end of the experiment. The results are presented in the form of graphs and enclosed tables.
