control options is to try to prevent the spread
of seed from site to site. At times, lawn mowing
equipment may carry seeds if not cleaned off
when moving between locations.
If you just
discover a few plants in a limited area,
removing them before they set seed may do the
trick. This is, of course, a limited option.
As with all types
of annual weeds in lawns, perhaps the best
control is to do the things needed to grow a
thick, vigorous turfgrass. For annual seeds to
germinate, they usually need some bare soil and
no taller plants hovering above to shade the
ground. To have these conditions in the lawn,
means that the desirable turfgrasses are not growing to
are pre-emergent herbicides that are labeled
for use on annual bluegrass. Proper timing is
important since these products will not work on
plants after they have germinated and have
started to grow. Check with your local
Service to determine the proper products and
timing for your area.
A few new
post-emergent herbicides may also be available
for use on growing plants of annual bluegrass.
Again, the timing is everything because once the
plants have set seed, it does little good to
kill the plant since the next generation has
already been assured.
