I have cleared an outdoor growbag of tomtoes covered in blight. The
plants are going of to the council tip, but what about the soil in the
growbag. Should I just dig it in to my veggie patch (I do not grow
potatoes) or should I put it in my copmost, or takr it to the tip? I'm
not sure if the fungii things will remain in the soil if I keep it.

Thanks

Council tip.

From <https://www.rhs.org.uk/advice/profile?pid=217>
"The presence of new blight strains in the UK means that the pathogen
now has the potential to produce resting spores (oospores) in the
affected plant tissues. The oospores are released from the rotting
tissues to contaminate the soil. These resting spores have yet to be
found in the UK, but analysis of the recent variations occurring in
blight strains in some parts of the UK suggests that they could be being
produced. Little is currently known about their survival and their
potential as a source of the disease, but investigations are continuing
and more information is likely to become available over the next few
years. However, because oospores are resilient structures, if they are
produced in infected foliage it is quite possible that they will survive
many home garden composting systems. This is why it is preferable to
dispose of waste from blighted crops in other ways. Municipal and
commercial composting systems reach the very high temperatures necessary
to kill oospores and other resilient pathogen propagules."

Thank you Jeff, good job I had not taken the other stuff to the tip yet!
