The title of the project:
Importance, reproductive strategy and integrated weed management of several perennial weeds
Head of the project:
Prof. Dr. Imre Béres
Laboratory and field experiments will be carried out to study the spreading, importance reproductive strategy, competitive abilty, allelopathy and nutrient uptake of Asclepias syriaca, Cirsium arvense, Convolvulus avensis, Phragmites australis and Rubus fruticosus.
Germination characteristics of the weed species have been also investigated.
Effectivity of the pre- and postemergence herbicides will be studied in pot and field experiments.
New weed host-parasite relations will be detected. Phytopathogen fungi on weeds will be isolated and their role in biological weed control will be discussed.
After summarizing the results of the experiments it will be possible to choose the most effective herbicides and combinations against the weeds and ecological factors, affecting the succesful weed control will be also known. We determine what phenological stages the weeds are susceptible to herbicides and make a model of weed management strategy in order to reduce environmental pollution and the use of herbicides.
