[Publius Scipio]

A few drops sprayed here and there would do the trick. I think a single drop would kill dozens,

Sure...if you were able to divide up and administer that drop by the microgram to each individual. Fortunately it isn't even remotely possible to deliver it with that kind of precision with artillery or aircraft even when using it on unsuspecting and defenseless civilians.

Conventional ordinance will kill you just as dead and it's much easier to handle and use.

Why be precise? This is a weapon of MASS destruction, not a sniper bullet. Nuclear weapons don't have to be precise, do they? Nor do commercial jets when flown into buildings.

Didn't a group in Japan do something similar with Serin gas? This stuff is worse.

I live in a mostly rural community. I can think of hundreds of ways to spread the stuff using farm implements
