Not necessarily. Stiltgrass germinates so late that early applications are running out of steam by that time. You need to make really sure that Pre-M is still effective around Memorial Day. See the first post in this thread for more info.

Andy,

So do you recommend prodiamine as a good pre M for stiltgrass? Or is there another pre M you would recommend for it? I used pendulum 2g in early spring but as you indicated if you don’t put a strong enough app down it will emerge all summer long which it’s doing in my yard again in small patches.

Prodiamine seems to work well, and is the only thing I have tested, so I can't tell you if others are better or worse.

Thanks Andy. I think I’m going to use prodiamine twice a year to help keep it down. Pendulum is too expensive for me to keep purchasing ($90 for a 40lb bag)
