What post-emergent herbicide is safe on dichondra?

Recently seeded a new dichondra lawn last fall. Problem is I have much poa annua (bluegrass); little bitter cress; and creeping charlie invading my dichondra. Can you recommend any post-emergent herbicides that can be used now while weeds are active? Also, are there any pee-emergent products that are safe on a dichondra lawn? If so, what time of year is best to apply? Your thoughts and suggestions are greatly appreciated.


Since Dichondra grass is a very sensitive grass and you do not ever want to use a herbicide containing 2-4D on it, it can be difficult to find the right products to recommend. For best results as a post emergent, it is recommended that you pull weeds by hand. Bensumec 4LF Herbicide is labeled to treat poa annua and has been proven very effective. Please read page 2 of the Bensumec 4LF label for detailed application instructions. Hope this helps and please let me know if there is anything else I can do to assist you.
