you like a cold kiwi fruit in the summer time,
this is a bit of bad news, morìa
and nobody really knows what it is, is spreading in France, Spain, Greece,
Turkey, Japan and China, but it seems to be moving at a much faster rate in
Italy, the frightening thing is that no one knows what it is or how to stop it, photograph Utsman
Media/Unsplash, scientists have been trying to figure out what is killing
kiwi vines since the phenomenon was first observed in Verona, back in 2012.
They looked at a variety of factors, from fungi and bacteria, to soil
composition and oxygen levels, but they are no closer to finding answers than
they were eight years ago, “It’s very difficult to study something like this,” Lorenzo
Tosi, a researcher with research company Agrea, told The Guardian. “When we want to understand the cause of
something, we try to isolate it and run an experiment. But that doesn’t work
this time because several factors are in play […] Everything seems to
contradict something else.” “This year, everything died,” Corrado Mazzi, a kiwi farmer
from Verona, said. “You can try all you want but nothing changes, in two or
three years, you are back to the start.”
Mazzi, and other kiwi farmers around Verona, tried everything
in the last few years. He uprooted all his vines in 2015, and planted new ones
in 2016 and 2018. He followed the best farming practices, but the morìa still
came back, with so few answers at their disposal, scientist have begun
speculating that global warming could be the main cause of this inexplicable
kiwi die-off. Research has shown that the ideal temperature for growing kiwi is
between 25C and 27C, but in recent years summer temperatures have shot up into
the 30’sC.
There is also the extreme rainfall that can choke kiwi vine
roots, but no such syndrome was recorded before 2012, so many are pointing the
finger at climate change, “I still have a lot of data to analyse, but everything seems
to point in that direction,” soil microbiologist Laura Bardi told The Guardian. “I’ve become convinced that climate change is
the main factor; if we study this aspect in-depth, I think we’ll find the
causes.” 8 years and still no idea if it is a fungi, bacteria or climate driven problem, that us a worry, not just for kiwi growers, but anyone that depends on growing crops for a living.
