Hi guys, newbie on the forum here. Have a question for someone with more experience than me with new switchgrass planting. I no tilled some seed back in mid may on ground I had used simazine on and 1 dose of roundup. Went over it a few times with the drill playing with seeding rates and apparently I disturbed the soil little heavier than I wanted. Got heavy crabgrass now. I mowed the other day. I do have some switch coming in but it's small. I'd really like to smoke that crabgrass, can I hit it with quinclorac now and not damage the switch?
