Southwest Minnesota
When do you spary your pre emerge corn herbicide? I've been spraying it right after I plant but would like to spray it earlier before I plant and maybe even when the fields are froze yet. Does anyone in my area spray it that early? If so, do you just up the rate a bit so it lasts longer or something else? I dont want to have to spray the corn three times.
