The best weedkiller for bindweed is a systemic weedkiller containing glyphosate, like Roundup Ultra. This is applied to the leaves and absorbed into the plant, killing roots, stems and leaves. The most effective time to use weedkiller on bindweed is in summer when the plants start flowering.

What is the best strategy for Bindweed removal & control? A herbicide application with a glyphosate based, total weed killer is the best bindweed killer option such as Gallup Home & Garden (non-professional option) or Roundup ProVantage (professional option)

Glyphosate is the best option to control a perennial species, like Field Bindweed, but it is not selective. The best selective chemical control for broadleaf weed control are products that include the combination of 2,4D+dicamba+MCPP, but a repeated application 10 to 15 days after first application may be required for 100% control.

A few herbicides that have been proven to do a good control job on Field Bindweed is 2,4-D, dimcamba, which is in banvel and glyphosate which can be found in round-up and touchdown. Post-emergent herbicide application of bentazon (basagran), acifluorfen (blaser), or gulfosinate ammonium (libery, ignite) can also suppress Field Bindweed.

Which herbicide is the most effective? The herbicide quinclorac is highly effective at controlling bindweed. Quinclorac is also a component of a few professional products. Quinclorac is available to the homeowner in the products Ortho Weed B Gon MAX plus Crabgrass Control and Bayer Advanced ™ All-In-One Lawn Weed and Crabgrass Killer.
