Has there been any research into the possible different characeristics of the strains and how they came into being?
I mean, if strain A is present in 2 different locations across the USA, will they both evolve over time into strain B? Or could one become strain B and the other strain C?
And seeing that in your country there are different strains now after 17 years, is it known how many strains came originally into the country from Asia? Or was that just 1 strain?
Is it known whether all strains need the same circumstances to spread and do they die at the same temperature? Is moving a DL from one place in the garden to another a problem, because for instance the temperature in that new place is different and a particulair strain of rust can only grow under those circumstances?
It's all só interesting!! I wish had the education and opportunity to research this myself!
