This question was brought up by a grower, thank you Jane Bush from AppleSchram. In the future, you can send such questions on the listserv so they can be researched and shared as this one.

 

Field Bindweed/Wild Morning glory, Creeping Jenny Organic Weed Management

http://attra.ncat.org/attra-pub/bindweed.html#cultural  is from ATTRA on organic systems to control bindweed. Here is a summary of findings to manage field bindweed in an organic system:

 

-  MOST Importantly: Don’t’ contaminate a “clean field” with pieces of bind weed or seed carried on your tractor or in poorly composted soil or in other organic matter.

-  bindweed does not survive well with light competition. This light competition can come from exclusion through

-  black plastic mulch- recover for 3 seasons or include some of following practices in the following years

-  planting a dense cover crop ((alfalfa or rye grass) or (hairy vetch and rye)),

-  Plant a crop of pumpkin in June and disk in crop residue after harvest (plant may contain an alleopathy to deter bindweed).

-  Till/cultivate land to cut bindweed when flowering. At flowering, the plant directs its resources to produce seed and away from roots.

-  Root grazers like pigs will eat leaves and chew on roots, greatly reducing reoccurrence

-  Cultivate soil or hoe to continually remove above ground portion

-  These practices (or combo of) need to be done for minimum 3 years of to actually KILL established bindweed. This is why it is ranked as one of the  “top ten” worst weeds in the world!

Each plant can produce 500 seeds that can last up to 50 years

 

Alternative herbicides such as clove oils and citric acid mixtures with vinegar. 

http://www.naturesoils.com/item--Citric-Acid--SO-CitricAcid.html?OVRAW=citric%20acid&OVKEY=citric%20acid&OVMTC=standard  is for citric acid which is sold and allowed by OMRI but restricted to kill weeds and brush at 20% strength.

Bindweed Mite:

http://www.cepep.colostate.edu/organic/factsheets/FieldBindweed.pdf   is an article from Colorado State University.  They discuss is a bindweed mite that may be useful in Michigan. It has been found to overwinter in Montana and Canada so could be useful on lighter soils. I say lighter soils as it does better in dryer conditions as found in southern Colorado. If any of you have info or experience on this please share with the group.
