Hello Douglas and Joe Nessim,
I am grateful for your valuable comments.
I thank Douglas for reminding me that actinomycetes are bacteria and not
fungi. Acinomyceters are filamentous spore forming bacteria that tend
to hang around a lot with fungi.Actinomycetes make most antibiotics.
Years ago when I was a student the actinomycetes were frequently called
fungi or undecided but that debate was cleared up a long time ago. Now
it is impolite to call actinomycetes fungi.
I understand that the spinosad is produced by fermentation and not by
chemical synthesis. So long as the insecticide is produced by bacteria
it seems artificial do differ it from Bt.
