Ekspresowa Analiza Zagrożenia Agrofagiem: Alternaria mali

Alternaria mali is a bagworm infecting apple trees (Malus pumila, M. domestica, M. sylvestris). It adversely affects the appearance and condition of trees, causing economic losses in the area of its existing distribution. It can generate the greatest losses in orchards and in areas with a high density of host plants. To date, no occurrence of A. mali has been reported in the PRA area, however, due to the presence of M. pumila, M. domestica and M. sylvestris and the favorable climatic conditions prevailing in Poland, there is a risk that the pathogen will spread if it enters. Although there is a low probability of entry into the PRA, phytosanitary inspections of imported plant material and vetting of orchards are recommended. Resistant apple varieties can also be used, and chemical protection can be applied if the pathogen emerges.
