Wintering ability of Calophoma complanata under the conditions of Saint Petersburg area

Wintering ability of Calophoma complanata under the conditions of Saint Petersburg area

Giant hogweed is one of the most widespread invasive alien species of the Baltic region. The pycnidial fungus, Calophoma complanata is being evaluated as a potential bioherbicide for control of Heracleum sosnowskyi. The aim of this work is to evaluate an ability of the potential mycoherbicide C. com...

The aim of this work is to evaluate an ability of the potential mycoherbicide C. complanata MF-32.121 to overwinter in the conditions of Saint Petersburg area.

When favorable conditions have arisen, the C. complanata MF-32.121 mycelium is capable to infecting young giant hogweed.
