About the use of fungicides and mycorrhizal fungi: any soil drench is going
to kill mycorr. But, contact fungicides that coat plants and don't
penetrate the soil are OK. I've found that neen seed oil works well on
tomato plants and roses. And, I previously (until 7 months ago) gardened in
the most fungi-riddled area of the country--on the hot, humid Gulf Coast of
Texas in Zone 9b. Blights, particularly, were the biggest enemies of
tomatoes. A profalactic spray program with neem seed oil worked well in
keeping early blight (septoria) at bay.
