When I was 15 years old, I started working at the Indiana University golf course in Bloomington where I cleaned golf carts, helped out on the driving range, and occasionally worked in the pro shop. While there I had the opportunity to meet the golf course superintendent, Brent Emerick, and I began to be more…Read more about Dr. Aaron Patton Joining Purdue as Turf Extension Specialist[Read More]
Due to the warm, wet weather we have been experiencing lately, homeowners are having to mow their lawns very frequently. Something to keep in mind throughout the summer is that the more often you mow your lawn, the more dull the mower blades become. Mower blades should be examined a few times throughout the growing…Read more about Sharpen Mower Blades[Read More]
Although it is generally preferable to fertilize home lawns in the fall, a late May fertilizer application can help the turf retain its color and vigor during the summer. If conservative nitrogen rates are used, fertilizer can be applied in late spring without dramatically increasing vertical growth. To aid the turf in keeping its color…Read more about May Fertilization[Read More]
Kentucky bluegrass, tall fescue and perennial ryegrass all produce seedheads that look unsightly in lawns. These seedheads are easily visible in maintained turfgrass because they grow faster and more unevenly than normal grass blades. Also, since the seedhead stalks are so tough, they do not cut cleanly and leave a light green or white tip…Read more about Managing Seedheads[Read More]
The Musser International Turfgrass Foundation has selected James Rutledge of Purdue as the recipient of the 2010 Musser Award of Excellence. The award, which carries a stipend of $25,000, was announced earlier this year at the Golf Industry Show in San Diego, Calif. Rutledge earned his Bachelor’s and Master’s degrees from North Carolina State University,…Read more about James Rutledge Awarded The Musser Award of Excellence[Read More]
Hunting billbug is becoming a significant problem in parts of southern Indiana where zoysiagrass is grown. These insects typically have two generations per year in this part of the Midwest with the larvae of both generations being capable of causing significant injury to turf. Sporadic adult hunting billbug activity has already been observed in the…Read more about Hunting Billbugs in Zoysiagrass[Read More]
Dandelions are one of the most common weeds of maintained turf because they can tolerate a wide variety of soils and environmental conditions. The best time to control dandelions or other broadleaf weeds is in the fall. Mid-spring is also an effective time for control, particularly when dandelions are flowering. If you wait too late…Read more about Dandelion Control[Read More]
For those that are managing cool-season lawns like Kentucky bluegrass, the ryegrasses or fescues the unseasonably early warm spring weather has resulted in quite a bit of shoot tissue (leaf clippings) being produced. For many that think they want their lawns to look like a closely cropped and highly manicured golf course, this may have…Read more about Warm Weather and Spring Mowing Woe’s[Read More]
As frequent users of pesticides, it is imperative that turfgrass professionals understand the terminology surrounding their formulation and use. For example, when we talk about ‘multiple targeting’ we are referring to an attempt to control more than one pest with a single application of pesticide. Timing of application as well as placement and formulation is critical to success. To time a…Read more about Professionals: Multiple Targeting with Pesticides[Read More]
Mid-August to mid-September is the best time to seed cool-season grasses. However, sometimes turf is damaged throughout the winter or the previous year and must be seeded in the spring. Spring seeding is difficult so there are a few helpful hints to ensure the most successful outcome. Seeding should take place early in the spring…Read more about Spring seeding[Read More]
In a few weeks, it will be time to apply preemergence herbicides for controlling crabgrass. Crabgrass germination starts in early May, or when soil temperatures are approximately 50 to 55 degrees Fahrenheit. Once germination occurs, the weeds are difficult to control. A good strategy would be to apply the preemergence herbicide before germination to inhibit…Read more about Crabgrass Control[Read More]
Last week’s warm temperatures really made the grass green-up and begin growing which means many people are starting to think about seasonal mowing. Probably one of the biggest mistakes homeowners make is not starting to mow their lawns soon enough. Remember the mowing “rule of thumb”. For optimum turf health “try not to remove more…Read more about Spring Mowing Tips[Read More]
With the winter snows melting away many are often surprised to find a series of tiny trails on the surface of their lawns and turfgrass fields. These are vole highways. Voles are often called meadow mice or field mice. While they are similar to a house mouse in general size and shape, they have some…Read more about Tiny Trails in Turfgrass[Read More]
The summary of our turfgrass research in the year 2009 is now available at www.agry.purdue.edu/turf/report/2009/index.html. The overall goal of our research program is to minimize inputs while maintaining turf quality, minimizing costs, and further protecting our environment. Our research summary contains reports of on-going research at Purdue University . The report is a cooperative effort from…Read more about Purdue Turfgrass Research Report Available On-Line[Read More]
Melting snows revealed some significant snow mold damage. As you know there are two types of snow mold diseases, gray snow mold (aka Typhula blight) and pink snow mold (Microdochium patch). Although they create similar symptoms (circular patches of tan turf—sometimes with orange/brown margins) the pathogens are not closely related and they have different temperature requirements for infection. …Read more about Snow mold damage[Read More]
There are literally thousands of fertilizers and fertilizer/pesticide combinations available to homeowners and professionals. Therefore, we can’t recommend how many pounds of a specific fertilizer to apply, but rather we must recommend fertilization rates in pounds of nitrogen per thousand square feet or lbs N/1000ft2. You can use our fertilizer calculator at http://www.agry.purdue.edu/turf/fertcalc/Fertilization%20calc.html or you can use…Read more about Calculating the pounds of fertilizer to apply[Read More]
As spring is closing in, we are fielding a number of questions four major questions right now: Which preemergence herbide to use? That one is pretty easy. We have only three active ingredients relatively easily available and they are dithiopyr, pendimethalin, and prodiamine. Our research shows that as long as they are applied at reasonable…Read more about Professionals Only: Premergence herbicide strategies[Read More]
There are many, many formulations and combinations of preemergence herbicides available for the professional. Following are some suggestions for purchasing and using preemergence herbicides. Control from every preemergence herbicide can vary from year to year, or location to location. Therefore, you can’t judge the performance of a product or a specific rate of that product…Read more about Choosing a Preemergence Herbicide[Read More]
Whether you are maintaining a professional, university field or a local soccer field because your daughter is on the team, it is difficult to get an accurate estimate of the costs to maintain an athletic field. From my experience, we tend to dramatically underestimate the actual cost of maintaining athletic turf. Tom Samples and his…Read more about What’s it really cost to maintain an athletic field?[Read More]
