During late March and April we get many calls about voles and vole damage in turfgrass. Voles are among the most important vertebrate pests in turf areas. Unfortunately the name ‘vole’ is very close to the name ‘mole’ causing some confusion and miscommunication. Even though both can damage turfgrass – the differences between voles and…Read more about Voles (remember the V)[Read More]
GCSAA’s nutrient use survey is now available and may have already arrived on GCSAA members desks. This survey will help document changes in cultural practices over time as well as help direct GCSAA research, and allow the GCSAA to respond to inquires on environmental and regulatory issues. Completing the survey will help provide the GCSAA…Read more about GCSAA’s Nutrient Use Survey[Read More]
Many of our pest problems in turf can be at least partially predicted through growing degree day models ( Poa annua seedheads is one example). Most of the models use a base temperature of 50 (abbreviated as GDD 50 ) assuming 50 degrees is the temperature when most of our biological activity starts occurring. GDD50 for IN…Read more about Tracking Growing Degree Days[Read More]
Now’s the time to get the mower out of the shed and start mowing (depending on where you live in the state). This normally happens well before most of us start mowing because we see mostly brown leaf blades and we don’t think the lawn is growing. However, grass plants grow from the bottom up…Read more about Fire up the Mower![Read More]
I have received a number of calls recently about controlling quackgrass in turf. Quack is difficult to control because it spreads by deep rhizomes and herbicides do not translocate well through the rhizomes. The current best method is with 3-4 applications of glyphosate spaced 3-4 weeks apart followed by reseeding in early August. Do not…Read more about Control of Quackgrass in Turf[Read More]
If a preemergence herbicide is justified on your lawn to control crabgrass now, most of those are available combined with fertilizer and you are forced to apply a fertilizer now. Look for a product with low nitrogen and be sure the majority of the nitrogen is a slow release N. Slow release sources include sulfur-…Read more about Choose Preemergence herbicides with as Little N as Possible[Read More]
Earthworm activity is on the rise as soils warm up, but their mounds will be highly visible until grass starts growing in late March and April. Earthworms are highly beneficial because they create channels for air and water penetration, reduce thatch, and tend to increase the fertility and health of a soil. However, some will…Read more about Earthworms Activity in Lawns[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]
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/1000 sq ft. You can use our fertilizer calculator at http://www.agry.purdue.edu/turf/fertcalc/Fertilization%20calc.html or you…Read more about Calculating the pounds of fertilizer to apply[Read More]
If a preemergence herbicide is justified on a turf area, the timing of application is important. In theory, applying too early will expose the herbicide to soil microbes and processes in the soil that may break it down, allowing crabgrass to germinate during the latter part of the summer. Conversely, applying too late may miss…Read more about Timing of Preemergence Herbicides[Read More]

Perennial ryegrass germinates quickly and provides quick cover and soil stabilization when used in a blend. However, too much perennial ryegrass leads to long-term problems from dollar spot, brown patch, red thread, and other diseases. Kentucky bluegrass has better disease, drought, and wear tolerance the perennial ryegrass, but is very slow to germinate. Hence bluegrass…Read more about How much perennial ryegrass Kentucky bluegrass in a mix?[Read More]

With the incessant rain and high winds, most applications of broadleaf herbicides have been delayed. The good news is its not too late to apply. Nebraska research reported in 2002 showed 2,4-D and/or dicamba were far more effective in controlling dandelions and Canada thistle when applied 1 to 10 days after the first fall frost…Read more about How Late is Too Late to Control Dandelions and Other Weeds?[Read More]
