 I know that they are poisonous if eaten,so wondered if they would be safe to use on compost that's  used on vegetables .
Seems a daft question to ask I know , but some people say it's okay, and I would rather be safe then sorry.

Yes, they're fine

Thanks Yorkie,
I wasn't sure because the plot owner next to me  just throws them on the ground and he has two large compost bins. I know people use them has a weed suppressant but that's all he seems to grow other then rhubarb

The toxicity of rhubarb leaves is much over hyped - you'll need to get through a good 5kg to eat a pretty convincing lethal dose. Of course less will still make you rather sick.

but won't harm the compost at all

A couple of chooks up the lotty ate some the other year and were dead by the morning.

I put them in the compost and haven't had any bother.

I have also read somewhere when mashed and soaked in water and put in a sprayer it is good to kill the caterpillars, haven't tried it myself tho.

.....when mashed and soaked in water and put in a sprayer it is good to kill the caterpillars,....

Unfortunately, as well as technically not being allowed, it'll likely kill off all insect life on and around the plants you spray.
