Summary of the Express Pest Risk Analysis for Macrophomina phaseolina

PRA area: Poland

Describe the endangered area: The entire PRA area

Main conclusions:

Macrophomina phaseolina is plant patogen fungus. Pathogen has a broad host range including cultivated and wild plants. Fungus is a heat- and drought-favoring and prefer regions with those climatic conditions. M. phaseolina was not reported in PRA area.. However, the pest occurence can not be fully excluded, because of low detection rate and little harmfulness. M. phaseolina may pose the risk to maize, tabacco and Leguminous plants crops. Fungus occurence is correlated with climatic conditions and inoculum availability.

Most of host plants and inokulum can not successfully overwinter in Poland, because of low temperature and high humindity. All of those factors limit pest occurrence in PRA area.
