Abstract
The purpose of this research was to assess the usefulness of 7 fungicides for protection of Lawson cypress (Chamaecyparis lawsoniana) against Phytophthora cin-namomi. Under the laboratory conditions, activity of the tested agents was assessed on the basis of growth of P. cinnamomi on a medium containing fungicides and the size of necrosis of the inoculated cypress shoots. In field research, the degree of infestation of plants in the infested medium. Laboratory research conducted indicated the highest effec-tiveness in limitation of growth of P. cinnamomi of Acrobat MZ 69 WG and Infinito 687.5 S.C. In field research, complete limitation of infestation of cypress with P. cinnamomi was achieved by applying two-component protection agents, containing propamocarb hydrochloride (Infinito 687.5 SC and Previcur Energy 840 SL), fosetyl-aluminium (Mildex 711,9 WG and Previcur Energy 840 SL) or mancozeb in combination with metalaxyl (Ridomil Gold 68 WG). Differences in terms of effectiveness of the agents examined depending on the application method were examined. Higher effectiveness was achieved through watering in comparison with foliar spraying using the same agents.
