I have a major problem controlling this trouble weed on my backyard.
I have sprayed the whole area with the liquid weed control I bought at
my local Home Depot two times but it did not appear to work. Perhaps,
I did not use the right one.

Could some body help me indentify the type of weed and hopefully
advise me what kind of weed control I should use.

Thanks in advance,


Here are link to the images I took:
