This is the bane of my garden and plants!  Bermuda grass!! I call it devil weed.

I've been searching for about 2 years to find a remedy.

By accident I just found it, while looking for something else.

There was a research paper (Researchgate) on the success of using mulberry leaf water extract, a 75% solution KILLS Bermuda Grass!!!

Who would have known, and I have loads of mulberry trees!

Here is the link to the article:  https://www.researchgate.net/publication/230020222_Mulberry_leaf_water_extract_inhibits_bermudagrass_and_promotes_wheat_growth

scroll down the paper and you will find how they make it, my short version is:


wash leaves thoroughly and let the leaves dry ( a few days)

soak dried leaves in tap water at 10%(w/v) at room temp (13-25 degrees C) for 24 hours,

filter to obtain a 10% extract

Then boil to concentrate it by 95% - this is now 100% stock solution.

Dilution of stock solution can be made to make 75, 50 or 25%

basically above 25% seems to block the bermuda grass from growing but they seem to recommend 75% or more

75% to 100% mulberry leaf water extract sprayed on the offending devil weed will kill it!

I plan to make cauldron's of the stuff!

Interesting paper. Most of our bermuda spread is from rhyzomes, and apparently it does minimal action on those but may be nice for sport spraying. More of a pre-emergent

Also works on the stolons:   "Stolons of bermudagrass were collected from the Agro-
nomic Research Area, University of Agriculture, Faisala-
bad, Pakistan.The stolons were cut into pieces to separate
the nodes. Each Petri dish of 9 cm diameter was filled
with 10 g of loam soil. Five fungicide-treated nodes of
bermudagrass were planted in each Petri dish.Then, the
25, 50, 75, and 100% mulberry leaf water extracts were
poured on the soil uniformly in the respective Petri
dishes. Distilled water was used as the control for com-
parison. All the Petri dishes (covered with lids) were
placed in a germinator (MIR-253; Sanyo,Tokyo, Japan)
at 25 ⫾2°C. The data on the sprouting, radicle and
plumule lengths, and fresh and dry weights were
recorded 12 days after sowing (DAS)."
