Hi

On my plot is some green powder in an unmarked bag in the shed left by the previous plot holder. Any idea what it could be?
 
Cheers

How big a bag ?

If it's a small bag it could be rooting powder, or it could be something which is decidely nasty.

Think I would ask the council where you can legally dispose of it personally.

Thanks for the reply. Its medium sized perhaps 2/3 of a supermarket carrier.  You're right it could be quite unpleasant!

what would happen to Bordeaux mixture over time?

Possibly green sulphur for dusting the onions.

Not safe to use any unmarked chemical though.

check if any of your plot neighbours knew the previous plot holder and what he grew or used -- green sulphur was often used when storing dahlia roots. Could be other stuff as well, best to dispose of it through a local authority approved disposal point.

With the greatest of respect to anyone, including brushcutter, this is just a guessing game. Only it isn't a game because some unidentified powder that may, or may not, be harmful is involved.
No one here is in a position to analyse and definitely identify this stuff via the written word on a website.

Would anyone even consider trying to identify a unmarked powder, or liquid, if it was left in a cupboard by a previous house owner. Would you ask the neighbours if the previous owner had a cough in case you might be able to use it.
I doubt anyone would pause to debate what it was.

There really is only one answer,  Get rid in a legal fashion through your local authority.

Absolutely right.  NOT worth taking the risk!

Up the tip it will go at the weekend, thanks for all your replies.

If there were deficiencies in the soil or possible disease problems i would be interested in the mystery powder.
If the plot or crops had a cough i would want to get a new prescription to remedy it.

Good for you. Make sure you put it in the special bin for chemical / garden chemical disposal, not just in the general landfill bin. If your council's anything like ours, you'll find the details under Waste & Recycling on their website. It may be that only certain tips can accept such wastes. And make sure it's securely packed so it doesn't react with other chemicals present & give off toxic fumes or worse
