I am seeking information as to the synergistic effects of the
chemicals metsulfuron-methyl  glyphosate  triazines when aerialy
sprayed particularly about the effect in spray drift, mist and fog as
we were sprayed in these conditions.  I have already asked this
question and don't want to be charged twice as I am on very low income
( like way below half of poverty line. My brain is fuzzy and I did not
notice that this program had deleted .au off my yahoo email address
and so I am doing it all again. I did not confirm the yahoo.com
account as I couldn't but Iam scarfed of being charged twice  WHat do
I do?

I am searching for an answer for your first question. 

As for you second question, I suggest you'll check up the FAQ
(https://answers.google.com/answers/faq.html) or contact
answers-editors@google.com - they'll probably answer it better than
anyone else (you probably have nothing to be worried about, but just
ask them to be certain).

In the United States, agricultural herbicides must pass certain safety
tests to be licensed for use on crops. These tests include interacions
with other common pesticides and herbicides. These three chemicals are
currently used together on many grain crops. Glyphosate is considered
the most dangerous of the three chemicals, and it does need to carry
EPA class III "WARNING" labelling. Still, glyphosate (sold as RoundUp
in Wal-Marts everywhere) is poorly absorbed by mammals, and generally
is excreted unchanged. Metsulfuron requires high doses to cause any
harmful effects beyond skin sensitivity, and triazines are found in
trace amunts (and higher) in drinking water systems all over the
country.

In short, the concentrations present when you were aerially sprayed
with these chemicals my be high enough to cause skin sensitivity and
burning eyes, but there is probably no concern of synergistic
interactions (each chemical acts very differently) or severe effects
from acute exposure. When working with agricultural pesticides and
herbicides, always wear appropriate personal protective equipment
(your employer should provide this to you) and take proper
precautions. ALWAYS read and understand the labels.
