About avocado sunblotch
The sunblotch viroid comes from the same places avocados do – Central and South America. It only affects avocados.
Global distribution of avocado sunblotch
Why this is a problem for New Zealand
Avocado sunblotch disease damages avocado trees and fruit, meaning fewer fruit are produced.
If the disease was found here, international trade in avocado fruit is likely to be affected.
How it could get here
The disease can’t survive for long outside of the plant, so it can only come into New Zealand in infected plant material or avocado stones.
MPI has strict measures in place to limit the chances of avocado sunblotch making it through the border.
But we need you to be vigilant too. Whenever travelling to New Zealand, always declare any food or fruit in your luggage. If you fail to do so, you could face a $400 fine.
