2013 Indiana Pesticide Clean Sweep Project
WHAT: An Indiana Pesticide Clean Sweep Project designed to collect and dispose of suspended, canceled, banned, unusable, opened, unopened or just unwanted pesticides (weed killers, insecticides, rodenticides, fungicides, miticides, etc.) is being sponsored by the Office of Indiana State Chemist (OISC). This disposal service is free of charge up to 250 pounds per participant. […]

Calibrating Ride-on Pesticide Sprayers and Fertilizer Spreaders: Keys to Application Accuracy (PPP-104)
Purdue Extension Publication
This publication addresses specific procedures for separately calibrating the pesticide sprayer and the fertilizer spreader of ride-on equipment. The goal is to ensure proper application to optimize performance.
Annual Ryegrass Showing Up in Lawns
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 […]
How to Mow Now That it has Stopped Raining
Tips for Mowing Wet Turf Sharpen your blades if you have not yet this spring. Mow in the afternoon when the leaf blades are dry if possible to reduce clumping of the grass blades. However, it is fine to mow wet turf or mow during light rain. Set the mower higher (especially if your grass […]
When Should I Apply My Preemergence Herbicide for Crabgrass Control?
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 […]
A Tale of Two Years
We are finally through a cold March and into what appears to be a normal April. The graph below compares January, February, and March in 2012 and 2013 to our 30 year normal weather averages for those months. The temperature outlook for the next three months has us with slightly above average […]
A Much Different Start to the Year
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 […]
Use Growing Degree Days to Better Time Your Applications
Monitoring growing degree days can be an effective way to better time applications and increase your weed control. A helpful website (www.gddtracker.net) is available to help you monitor growing degree days for timing herbicide and plant growth regulator applications. What can this website help me with? Need help determining when to apply your preemergence herbicide? […]

Read the Label! A Hard Lesson Learned
I was recently forwarded a video from one of our Extension educators in Vanderburgh County, Larry Caplan, that I thought I would share with you. The video chronicles the “misadventures” of a homeowner who simply wanted to control the weeds in his lawn. It should be a reminder to all of us to read the […]
Turf Field Day: Another Hot Day in the Sun
Thanks to all the 459 attendees and 32 exhibitors who attended the Midwest Regional Turfgrass Field Day Tuesday, July 17, 2012 at the W.H. Daniel Turfgrass Research Center in W. Lafayette, IN. We had golf and lawn research tours in the morning, two different afternoon tours, and two afternoon workshops and addressed many current topics […]
My Lawn is Brown and Crunchy… Is it Dead? What do I do now?
The first day of summer/longest day of the year for 2012 has come and gone and just this past week a new National Drought Monitor Map was published (see below). The city of West Lafayette in Tippecanoe County has now fallen into the “Severe Drought” category. In fact 36% of Indiana is now in […]
Measuring Pesticides: Overlooked Steps To Getting the Correct Rate. (PPP-96)
Purdue Extension Publication
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.
Assessing Spring Freeze Injury in the Landscape
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. […]
Crabgrass is Now Germinating at Most Indiana Locations
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). The GDD Tracker estimated that crabgrass germinated in Lafayette, IN after Wednesday this week and I was able to confirm this by identifying newly germinated crabgrass (see figure below) both […]
When Will Crabgrass Germinate?
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 […]
