Anyone know what this is or how to kill it? Full rate (and then some) Trimec with sticker does nothing...Red Zone full rate nada. It kinda came out of nowhere last year and is exploding this year. It grows to the top of the grass and will crowd out the turf wherever it is. I will send a cashiers check for $50 to the first person that can ID and prescribe EFFECTIVE treatment.....and no guys, it isn't crabgrass.
