Olá! I don't think it will matter, because many times the problem starts at the nursery. There are many nurseries, both inside the EU but also outside, like Morocco for example. When orchards are being installed across the country, it really could start anywhere. Weather does not seem to have any importance in the spreading of the disease. What happened with the palm weevil (Rhynchophorus ferrugineus) doesn't necessarily apply here: X. fastidiosa infects a wide range of plants including ornamental plants, so it is really a matter of 'when', not 'if' or 'where'.[1] As of February 2017, there were 132 confirmed cases in Balearic Islands that are now considered lost for the bacteria.[1] As far as I know, there are no confirmed cases in Morocco, which is why many farmers look there for safe nurseries.
