Crabgrass Emerging

Back on May 24, I posted about my observation of crabgrass emerging in areas that had very thin turf cover and very high levels of crabgrass seed in the soil. Crabgrass is now emerging from areas with healthier turf and good density (and has not received a preemergence herbicide application). Recent and forecast rains are likely to intensify crabgrass pressure over the coming days and weeks. It is time to start scouting areas for breakthrough of crabgrass, if this is a concern. Postemergence control options were summarized in my earlier post.

You can see our herbicide evaluation trials (synthetic and organic products) during the Rutgers Turfgrass Research Field Days on 30 and 31 July 2013 at Hort Farm No. 2 in North Brunswick NJ. You can register online for one or both days; click here to register.
