Smooth Bedstraw (Galium mollugo) is becoming
more noticeable on farms.

This is a perennial weed that reproduces by seed and
by roots. The stem is square, smooth, 20-70 cm long, and weak. It
grows in clumps and leaves are in a whorl (8 leaves).

Control & Prevention
- Seeds: Buy clean seed "Certified". Bedstraw
has been spreading from farm to farm in the Bird's-foot trefoil
seed. The seed is of similar size to trefoil and cannot be separated.
If someone offers you common seed, at least get a purity test
done on it. For approximately $30.00/sample you can find out if
the trefoil seed is contaminated with weeds such as smooth bedstraw.
Paying less for common pure trefoil or mixtures one year could
end up costing you more in the long run. You may obtain a list
of the laboratories that offer seed purity testing by calling
- Herbicides: In the hay field, when you identify the bedstraw
you can spot spray these clumps with Roundup or Touchdown. If
the weed infestation is too severe, you must spray the entire
field prior to plowing, with either Roundup or Touchdown @ 1.5-2.0
L/acre. For more information consult the OMAFRA Publication 75,
