Rick:

Just ask the farmers what they spray. Straw will most likely have less,
being a byproduct rather than the primary crop as in hay. Seed content
is fairly high in the straw we get in NE GA. But if any does sprout it
dies in the heat.

Good Luck!

Thanks for all the advice.
can't get wood chips I thought I might try to buy straw from local
farmers for ground cover, and use cattle panels in rows for the
tomatoes to climb on.
