Tin based pesticides
I have some Citrate and Acetate Tin solutions. Is it possible to synthesize any of the Tin based pesticides from it shown in this picture?
I'm planning to use it on my potato plantation to kill Colorado Beetle.
Would any of the tin end up in the harvested potato ?

I have allergy on honey, not worried about the bees in the area...

If you kill all of the bees potatoes might be all you get to eat, because without them many of the fruiting plants you may intent to grow will not
produce fruit without pollination.
That aside, fentin acetate and fentin hydroxide are fungicides and will not be effective on Colorado Beetle.
Azocyclotin will be somewhat effective, but no where near as good as other products you can likely get in your local hardware store.
Fenbutatin oxide will be the most effective of the bunch you have listed here and is the only one designed for organisms like your target species.
In general organo-tins are quite persistent in the environment and very bioaccumulative. They are also bad news for aquatic organisms. I wouldn't be
putting them in my potato patch, but that is more because I like to promote high biological activity in my garden, less from a human health
perspective.

These organotin compounds are very harmful for the environment, and for that reason they have been banned in Europe and the US. Additionally, these
are fungicides, not insecticides, so they’re completely useless to you! There are plenty of more effective and much less ecologically harmful
insecticides that are readily available. Do some research and figure out what you actually need.
Edit: sorry B(a)p, I didn’t see your post because I typed mine up hours ago and forgot to hit submit until later. I realize that I essentially said
the same thing as you

Different people have different problems.
I have several kilos of a fenbutatin-oxide containing pesticide (from before the ban, the bags are probably decades old) and I would like to recover
the tin from them. 
I have the feeling that metallic tin would be more useful for me.
Regarding the original question I think these compounds are made via organometallic reagents (direct Sn-C bonds) so your "starting materials" are
prbably not good for the synthesis.

Since C-Sn bonds are pretty unreactive, your best bet would likely be to burn the material in an oxygen-rich environment until you’re left with
nothing but tin(IV) oxide that you can reduce to the metal. How to do this safely without releasing copious toxic fumes? I don’t know. Also depends
on what other ingredients are in your pesticide product.
