I don't know of any association between bindweed and beans or peas. Why not treat the bindweed with Roundup now and this autumn as it starts to die back?

I would also paint it on, rather than spray it on, so you get less in the soil.

Sadly it has now been proven that roundup leaves a toxic residue in the soil...

I learned that in the early 90's, but no one would believe me!

The bind weed really needs to be dug out and burnt or disposed of in the wheelie bin.

But there isn't any reason not to grow peas or beans next year, is there?

None what so ever...

Do keep an eye out for bindweed seedlings and pull them as soon as you see them. The seeds can stay viable for more than 5 years in the soil. If you let a seedling bloom, you'll be starting the clock all over.

I found it wasn't the seedlings that were the particular problem with bindweed. It's the little bits of root left in the soil that sprout again all over the place. No matter how often you pull them out there's always some left to regrow.

That, too, but they will eventually starve to death, if you can keep them from going more than a week with leaves. If we want to be positive, we could call it "job security". : D
