Re: [nafex] Pestacide residue

Best thing to do is check with your certifying agency.  We were in a
similar situation - we washed out the tank with an environmentally safe
cleaner with good surfactant qualities numerous times including running the
wash water through the lines.  We also left the spray tank lid open (basket
in place) over a lengthy period of time.

Other than having the water from the tank tested we were hopeful that the
residue was considerably reduced.

Please let me know how your organic strategies work.  I've only heard good
things about kaolin.  Ensure that any sulphur formulations you use have a
good sticker/spreader.
