where do you find that stuff at?
Â
lul, nicotine is 10x more toxic than imidicloprid to humans and mamals,it will kill bees in droves given its non systemic and must be sprayed more frequently. it could easily kill youself your pets etc.Â
'bee' careful sir. lolol

Turns out that imidicloprid does not have a 30 day half life. It's much more persistent, poisoning the ground and any plants growing in it for years. IMO, there is no 'safe period' during which you can use this stuff as a ground treatment. If plants growing in treated soil make flowers, any bees visiting those flowers will be affected. To make things worse, most neonicotinoids will slowly accumulate in the bees' bodies, much like mercury, etc. accumulates in vertebrates, eventually causing illness and neurological disruption of the bees' behavior. If you're going to use this stuff, be careful!
Â
it does have a half life around 30 days, where have you seen otherwise?
yes it will remain in the soil for years, but at levels not now known to be dangerous according to epa etc. its broken down very quickly via sunlight, and surface water films. like in a few hours.
Â
do you know who just loves to contaminate the ground with toxic copper? you know the stuff that kills fish and aquatics?Â
organic farmers. the stuff is sprayed at a rate ( i think) of 10s of millions of tons a year, as a crude, yet organic fungicide.
Â
crude organic coper sulfate is wholly inorganic chemically speaking, and hence accumulates nicely in the environment, whereas synthetics dont, as they can decompose via a variety of mechanisms.Â
copper sulfate is organic tho, so the contamination is acceptable?
Â
it does not accumulate like mercury. you are misunderstanding a key thing about bioaccumulation. it is known to readily metabolize via super simple hydrolysis, and persists very poorly in the environment UNLIKE METHYL MERCURY which you misunderstand.

bees are thought to be very smart as far as insects are concerned anyway, last i heard, the concern was that sub lethal doses basically damage their brains, making them unable to find their way back to the hives.
