The methods of regulation the Elytrigia repens (L.) Desv. on arable land
 KOCEK, Václav
Weed infestation of the arable land by persistent weeds is serious problem today. Very dangerous species occuring in all crops, not just only on the arable land, is "Elytrigia repens". It's spread is connected with decrease the level of tillage and with reduction of agrotechnical measures. The target of my thesis is to broadening of knowledges and to suggest other possible solutions of regulation of the occurrence of "Elytrigia repens". SO we did an herbicidal attempt at "Triticum aestivum", which was focused on chemical regulation of this weed. There were used three herbicidal products in different variants. Using of herbicidal products reduces the occurrence of weed species.

Biology and control of catchweed
 VONDRUŠKA, Jakub
A very limited range of crops provides the human nutrition. In some time there was selected a little amount of weedy species that plays an important role with respect to quantum and danger. Galium aparine belongs to these species. Therefore an herbicide experiment was carried out with Triticum aestivum catering for a chemical regulation of this weed. In particular 26 varieties of a half of a hectare there was used 21 herbicide preparations and their combinations altogether in demanding conditions of low preparation of soil. It was realised at a land with a large amount of Galium aparine. Most of the preparations had a very good effect regarding the actual control. At some of them Galium aparine nevertheless outgrew and produced seeds. Although these seeds were produced in a little amount, they supply the reserve in a soil. In the literary recherche are described biology, harmfulness and potential methods of regulation of Galium aparine.
