Which statement accurately describes the status of phylloxera in South America?

The statement that phylloxera has never been experienced in either Chile or Argentina is accurate because both countries have managed to avoid the widespread devastation caused by this root louse that has affected viticulture in many other regions around the world. Chile, in particular, has stringent regulatory measures and unique geographic conditions—such as its natural barriers like the Andes Mountains and Pacific Ocean—that have helped keep phylloxera at bay.

Argentina, on the other hand, has also reported areas in which phylloxera has not been present and employs various practices to prevent its introduction and spread. This enables both countries to maintain their grapevine health and sustainability in viticulture, distinguishing them from regions where phylloxera has caused significant damage.
