Testing has been underway on a new selective control in C3 grasses for annual bluegrass, poa triv, quackgrass and yellow nutsedge. Wouldn't that be a great product? Not named yet, known as MON 44951, and won't be out until 2004 at earliest. Testing on bentgrass so far has gotten 70% reduction of poa triv, without unacceptable phyto to bent. Needs multiple apps, and timing and # of apps is still being worked out. Purdue also testing TranXit 25 DF on C3 turf. This is a selective P. annua and P. trivialis control used on C4 turf now.
