I have had several emails and weed samples submitted recently of an unknown grass. In each case, the sample was annual ryegrass (Lolium multiflorum). Annual ryegrass is a common ingredient in low quality seed mixtures. It appears in the spring time in lawns seeded the previous year either from some annual ryegrass in the seed…Read more about Annual Ryegrass Showing Up in Lawns[Read More]

However, it is fine to mow wet turf or mow during light rain. Set the mower higher (especially if your grass…Read more about How to Mow Now That it has Stopped Raining[Read More]
Despite proper cultural practices, crabgrass may still remain problematic in certain turf areas. The best approach to controlling crabgrass is to use a preemergence herbicide such as dithiopyr (Dimension), pendimethalin (Pendulum), prodiamine (Barricade), prodiamine + quinclorac (Cavalcade PQ), sulfentrazone + prodiamine (Echelon), and others. These herbicides inhibit cell division and prevent crabgrass seeds from properly…Read more about When Should I Apply My Preemergence Herbicide for Crabgrass Control?[Read More]

A year ago we had record high temperatures and we were scrambling to apply preemergence herbicides for crabgrass control. On March 22 last year, I had crabgrass germinating in my garden! However, this year I can tell you that crabgrass is a long ways off from germinating today. The chart below shows the dramatic difference…Read more about A Much Different Start to the Year[Read More]

This publication describes steps that pesticide applicators can take to correctly measure and mix products to improve results, save money, and enhance safety. Specifically, it will explain some common myths about measuring pesticides, distinguish the difference between liquid ounces and dry ounces, and offer solutions to common problems associated with measuring devices for liquid and dry pesticide formulations.
As most gardeners have marveled, we’re having one of the earliest “spring” seasons this year, with woody plants and herbaceous perennials three to six weeks ahead of “normal.” And then, perhaps inevitably, “normal” spring frost and freeze visited. Being so much further along in their development, plants are quite vulnerable to damage. …Read more about Assessing Spring Freeze Injury in the Landscape[Read More]
The GDD Tracker website (sponsored by the MRTF and Purdue University) is predicting that crabgrass is now germinating at most Indiana Locations (see figure below).

A new turf publication has been posted on the Turf website: Facts About Phosphorus and Lawns – AY-334 https://www.extension.purdue.edu/extmedia/ay/ay-334-w.pdf
With the rapidly warming weather, several are asking “When will crabgrass germinate?” The reason this is so important is because preemergence herbicides used for the control of crabgrass must be applied prior to emergence (except dithiopyr (Dimension) which can be used postemergence on crabgrass up to 1-tiller). There are several different ways to try and…Read more about When Will Crabgrass Germinate?[Read More]
