Plateau herbicide for annual weed control

mwbeall(IN5 E tallgrassregion)March 15, 2006

I just read an article at on use of Imazapic (Plateau) an imidazolinone herbicide which can be applied PPI, PRE, EP or POST to control weeds in seedings of several prairie grass and forb species.

I have planted a plot this winter and am anticipating annual weed takeover when the ground warms up. Should I be concerned and what do you think about the treatment? Please give your best advice. MWB

here is my 2 cents worth...

first, annual weeds takeover ALL new plantings, thats the way momnature works. but the solution is right in the name, annual. mow so no seedheads form and ull never have a problem with them. infact, a local dnr guy calls annual weeds a nurse crop vs a prairie seeding in the correct soils. prairies are long distance runners vs annual sprinters, they will run outta gas sooner or later...

as to Plateau, im not convinced. i have a testplot that i drive by atleast 2-3 times a week. the area definately looks more 'grassy' 3 years into the program. im not convinced that Plateau is an answer and this test plot isnt helping the opinion.

imho, if its not a perennial, dont sweat it.

BTW: the annual weeds of which I speak are Whitlow grass (Daba verna), Gill-over-the-ground, and mouse-ear chick weed.
