GV Seed Savers

I have problems with tomatoes over the last few years. The plants seemed to be getting a disease called spotted wilt. I grwo rouge de marmande tomatoes because I like the flavour and they are a bit earlier.  Apparently this disease is spread by western fruit thrip. I have been trying an organic pesticide called spinosad. This is marketed under the name Success by yates. So far no spotted wilt - fingers crossed.
