Roundup will kill it. Scout and spray early , condition your water , and up the rate 30-50%. If the marestail gets too tall then you are screwed.
BTDT. Water conditioners, full rates. It will NOT touch the spring annual weeds that go straight into bolt stage with Roundup alone. And this stuff is less than 1" tall too. And I have seen escapes traveling through Indiania so consider yourself lucky. |
