I have a war going on with bindweed (AND burdock AND curly dock). With bindweed, it will take some sweat equity to eridicate it. Here are the steps, AND do as I SAY, NOT as I have always done, bc I have 5 acres and fencing to tend, so some doesn't get done:
1) DON'T let it go to seed
Bindweed makes more bindweed from seed pods, that look like "Invasion of the Body Snatchers"...but smaller.

Who knew? I was just out in the garden ripping up Bindweed—yet again, sigh—when a truck showed up with USDA flyers about an invasive species moving up the banks of the Bear River Preserve into the neighborhoods.And sure enough, the plant turned out

They are green, about 3 inches long, and open to spread their seed in early Spring. Throw them in the trash.
It won't hurt a landfill to have bindweed growing there!
They, like many other successful weeds/plants/trees (like Aspen), send runners out underground.
2) Dig deep with your shovel to remove underground runners and THROW THEM IN THE TRASH.
NEVER, NEVER compost these bc they will proliferate in your compost pile!
I bring my wheelbarrow, a bucket, and wear gloves, and hand manipulate the underground bindweed runners out of the soil. The runners go straight into the bucket and then into the trash can in the garage, and the dirt goes back where it was.
3) Buy 2D-4 herbicide and a cheapo package of children's paint brushes. Save a "to go" plastic glass. You will want to mix the dilutable herbicide and 1/2 fill the plastic glass. Save the lid and put the paintbrush through it. Refill, as necessary, but 1/2 full means less to accidentally spill.
ANY bindweed that you cannot dig out can be treated with the herbicide by paintbrush and have a minimum impact of other nearby plants.
I have pretty much eradicated whole beds of bindweed, but be ready to dig maybe over a foot deep.
DON'T worry about breaking them with your shovel. Just dig deeper. They won't explode like a mushroom which sends spores everywhere.
