...in reading this (and please correct me if i'm wrong), it does not 
say that it degrades in contact with water....what it says is that it 
degrades in _ground water_...which is not water, but wet 
soil/sand/loam (the document is very specific about this).

in water, the document claims that fluvalinate is subject to 
photodegradation when it is in water...meaning that water does not 
break it down, but in the presence of water, photons (light or other 
em frequencies) break it down.  it is not specific as to what 
wavelenghts cause this...it is certainly within the realm of 
possibility that it is only uv light (that is blocked by a glass jar) 
that causes this photodegradation.  if this does break down in in the 
jar due to sunlight, one of the resulting substances is 3-phenoxy 
benzoic acid...not much data as to the saftey of eating this on your 
toast.

the document also cites the "sorption to sediment, suspended 
particles and plants"...in the case of honey (if it were water), you 
are eating any suspended particles that fluvalinate has been bonded 
to.

THIS DOCUEMNT SPECIFICALLY SAYS: "Fluvalinate is stable to hydrolysis 
under normal environmental temperatures and pH"...which means that 
water does not break down fluvalinate.  to be precise:  "fluvalinate 
does not break down in contact with water, it breaks down in water 
when exposed to some wavelenghs of em, and it binds to sediment and 
suspended particles"

also, honey is not water, and it would be a mistake to assume that 
fluvalinate would act the same way in a hydroscopic liquid (honey) as 
it does in water.  just because a goldfish thrives in water does not 
mean it thrives in honey.

with
