Biology, presence and methods of weeds regulation on a land planted with permanent grasses.
ONDRÁK, Aleš
This thesis is aimed at biology, presence and methods of weeds regulation on a land planted with permanent grasses. Lately, ruderal weed species have been spreading uncontrollably throughout the lawns. It is very difficult to control their occurrence and also very economically challenging. Therefore, the farms should focus more on the possibilities of preventing excessive weed infestation and they should also define and apply the cheapest and the most favorable precautions. On the grassland, which belongs to the ZD Třebelovice, were observed the most abundant weed species. The weeds which occurred the most were: Taraxacum Officinale, Rumex Obtusifolius L, Ranunculus Repens L., Geranium Pratense L., and Urtica dioica L. The influence of the individual hay cuts on the occurrence of the chosen weed species was monitored. The influence of various herbicides was also the matter of observance. The componential task was to appraise the achieved effect after applying chosen herbicides on the weed species.
