Field bindweed is difficult to eradicate because it has a taproot
that can grow to a depth of 2.5 meters (10 feet).
Bindweed can be managed through
cultural control when
alfalfa, rye, soybean, and sorghum are planted because bindweed
cannot compete for light with these species.
Bindweed can be controlled using mechanical techniques. Intensive
tillage can kill young field bindweed infestations. However, tilling
must occur
every 8-12 days throughout
the growing season.
Bindweed can also be controlled with chemical herbicides when it
is actively growing and stems are at least 30 cm (12 inches) long.
Re-treatment is required because of seed and re-growth from roots.
The effectiveness of herbicide is reduced when weather is hot and
dry.
Scientists are searching for biological control agents for this
weed. Gall midges, mites, and bindweed moths have been tested but
have not proven to be effective.
Field bindweed often must be managed using a combination of all
available techniques.
