"A study in New Zealand showed that glyphosate significantly affects the
development and survival of one of the most common worms in its agricultural
soils. Applications every 15 days at low doses (1/20 the normal dose)
reduced growth and increased the time for reaching maturity and mortality."


They say that the worms were treated every 15 days(!) then go on to say that
growth was 'reduced' and time to reach mortality 'increased'??????? - are
they saying that it will make worms live longer? - no figures are mentioned.
They do have an axe to grind though and I am loathe to beleive this type of
site.
