I am battling an infestation in one part of my yard.
Last summer, I tried spraying it,but it is back again.
Most herbicides, including Roundup, are ineffective against bindweed. At most, they cause browning of the leaves, but don't kill the rhizomes and roots. Tordon (picloram) is perhaps the only herbicide that actually kills bindweed. But, the decision to use Tordon shouldn't be made lightly. It is both highly persistent (typically takes YEARS to break down) and mobile in soil, two rather undesirable characteristics in any pesticide.
