I have been trying (obviously unsuccessfully) to rid my residential yard of this winter and spring pest for years to no avail! The closest I have come is using Fert-alome fall application about this time of the year which takes care of about 90% of it! Do you have any other suggestions (preferably a liquid application) that will be more effective??

In your article entitled 'Poa Annua control - Poa Annual Grass Treatment for Lawns,' you mention pre-emergent herbicide. Can you recommend such a herbicide that is available in the UK? Thank you.
Unfortunately we cannot recommend specific products. A local gardening store or nearby university with a horticulture program may be able to help.
