The farmer at one of my out apiaries has tonight telephoned me to say that he plans to sow corn in a months time.

The field that my bees are in is only 10ft away and the bees use the field as the flight path into the hives.

A week before sowing he plans to spray with a Glyphosate(Roundup) I have had a look on Google and from what I can see the bees should be ok?

Does anyone have any advice for me,should I shut the bees in during spraying and for the next 24 hours?

Roundup spraying is very common procedure on farm fields.
I have not met or seen mentionings that it makes any harm to bees.

Roundup is not a stuff which disapears in 24 hours. It affects 3 weeks and then you may put into earth what ever.

Roudnup has special odor but I don't know what bees like it. They take drinking water from soil to larvae feeding.

I've watched a salesman drink neat RoundUp, the only ill effect was the fact he continued to work for Monsanto!

I have used Roundup (Glyphosate) for years to keep areas that I cannot cut/strim tidy with no adverse effects on the bees. It is a systemic Herbicide and the blurb says it does not effect insects when used as per instructions. It is horrendously expensive so I have never heard of anyone using too much:)

As roundup is a herbicide, ie weedkiller it should have no effect at all on bees.

Personally I would leave them alone.

Also you have a good guy there communicating well with you. Nice one.

I wonder whether it would be a good idea to keep them in while the foliage is wet. I think glyphosate is sweet tasting. Animals have been poisoned, not by ingesting the glyphosate but because they ate poisonous plants and the normal bitterness was offset by the glyphosate. So whether it contains some sweet substance that would attract bees, that you would not want in your honey, i don't know. It would not hurt to confine them for the day.
