Upcoming Open Positions on the MRTF Board of Directors
There will be a number of openings on the MRTF Board of Directors in the upcoming December elections. MRTF’s mission is to support research and education and thus help advance our industry. We are looking for potential board members dedicated to our industry and desiring to help steer the direction of turfgrass research and education. […]
A Dry Lawn in October is Reason for Concern
Though areas of Indiana received some rain this week and more is forecasted, most of the state has received precipitation far below normal. Many lawns look as brown now as they normally do in August. This does not bode well for winter survivability of grass and the appearance of the lawn next year. September and […]
Coping with Late Season Drought in Turf
(Adapted from the Midwest Regional Turf Foundation Factsheet, Oct 1, 2004) After an extremely wet summer, turf drought stress has come out of nowhere almost throughout the state after a dry August and September. Though September and October are prime growing months, turf will not recover unless the turf receives ample rain or irrigation soon. […]
Turf and Ornamental Seminar
Mark your calendars for Nov 15-18 for MRTF’s Turf and Ornamental Seminar. Like last year, the course is advanced for lawn care, golf course, sports turf, and sales staff. The lawn care session will be on Monday and Tuesday, Nov 15-16, while the golf, sports, and sales session will be on Nov 17-18. Topics include […]
Bermudagrass for Southern Indiana Athletic Fields (AT-325-W)
Purdue Extension Publication
Turf quality on municipal athletic fields in southern Indiana is typically poor due to excessive traffic from football and soccer. But reseeding worn areas with some common grass varieties in late spring or late fall aren’t always successful. This publication explains how bermudagrass can be a potential solution to worn fields in southern Indiana.
MRTF Golf Day at Coyote Crossing on Oct. 14
Openings are still available for the MRTF Golf Day on Oct 14 at the Hale Irwin-designed Coyote Crossing Golf Club in West Lafayette. This is the seventh annual event held to promote turfgrass research, raise awareness of the Purdue Turfgrass Science Program, and provide an enjoyable day of golf. It’s an early morning event starting […]
Gray Leaf Spot 2004
We’ve received several reports of gray leaf spot outbreaks throughout the state during the past couple of weeks. It may surprise many, because the summer of 2004 has been one of the mildest (zero days where temperatures reached 90 F in West Lafayette) in recent memory. It did not surprise us, however, because our research […]
Rust Revival!
Well it must be September and it must finally be dry because I have seen some serious outbreaks of rust on many perennial ryegrass lawns throughout the area over the past week. Leaf rust has been most noticeable on lawns that are newly planted and malnourished, both excellent conditions favoring the development of this turf […]
Attempting Ground Ivy Control
I’ve received a number of calls recently on ground ivy control. Here’s a rerun on an August Turf Tip on controlling ground ivy. Background Ground ivy is difficult to control and it is a problem in 31% of lawns maintained professionally in Indiana. Earlier research by Eric Kohler has expanded our understanding of ground ivy […]
Late-summer Aerification check-List
Although this past growing season across most of Indiana has been cool and moist this is no reason to consider skipping fall core cultivation or aerification. In fact, this abnormal weather pattern is actually more conducive to thatch accumulation since many of the microbes responsible for organic matter break-down are less active in these conditions. […]
Purdue Turfgrass Research Report Available On-Line
Though members of the Midwest Regional turf Foundations received compact discs of our 2003 Research Summary a number of weeks ago, the same research summary is now available online at http://www.agry.purdue.edu/turf/report/report.htm. 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 […]
More Evidence for Effectiveness of Fall Applications of Broadleaves
It’s been fairly well established that fall applications of herbicides are more effective than spring applications for broadleaf control. Recent work in Nebraska reported that applications of 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 than when applied 5 […]
Wait to Control Broadleaf Weeds
Though many broadleaf weeds like ground ivy, clover, and plantain are currently thriving in turf areas, resist the urge to spray them now. Following is a summary of a study that we discussed at Field Day that can help professionals improve broadleaf weed control, especially difficult-to-control weeds like ground ivy. Background Ground ivy is difficult […]
Thinning Turf Around Lawn Perimeter from zero-turning radius mowers
The popularity of the new zero-turning radius mowers is well-justified in terms of time and energy saving devices. However, these mowers are much heavier and faster than walk-behind mowers and thus increase compaction and turf wear. This is especially important around the perimeter of lawns (commonly referred to as the clean-up passes) where the mower […]
Brown Tracks in Lawn
I’ve seen lawns and heard this week about brown streaks that are about the width of the mower (photo). In the vast majority of the cases, these tracks are caused by the weight of a mower traversing across a portion of the lawn that was drought-stressed. Drought stress may not have been easily visible before […]
Reminder of Midwest Regional Turf Field Day on July 27
The Midwest Regional Turf Field Day will be held on July 27 at the Wm H Daniel Turfgrass Research and Diagnostic Center in West Lafayette. This is a great opportunity for turf professionals to view the latest in turfgrass research, talk to Purdue specialists about turf and ornamental issues, and visit with exhibitors displaying the […]
News about Japanese beetles is mostly bad!
Japanese beetles are back! They appeared 10 days to 2 weeks earlier than normal this year and indications are pointing to a very heavy population in many parts of the state. Last years weather conditions kept soils moist which apparently led to a very successful grub hatch. Early emergence usually points to a somewhat earlier […]
Finicky Poa annua Yellowing and Thinning on Greens
In spite of the cool and dry weather, Poa annua continues to yellow and sometimes thin on golf greens. Last week Poa annua was thinning and dieing in low areas from too much water, heat, and humidity (photo). However, the cool dry weather over the weekend allowed for maximum water loss through evapotranspiration. Plus since many irrigation systems were […]
Summer stress of Poa annua and Poa trivialis in Lawns and Sports Fields
Poa annua (annual bluegrass) and Poa trivialis (rough bluegrass) in athletic fields and lawns are starting to show signs of stress. The signs of stress include laying over (poor mow-ability), yellowing, and thinning. Patches of these fine-bladed grasses seemingly die overnight with even a minimum of drought stress. Though these grasses may have blended in with the desired turf […]
White Clover in Golf Courses, Sports Turf, and Lawns
The small white flowers of white clover are very visible right now and it may appear that clover is taking over, especially under-fertilized turf areas. Clover is a legume and is very competitive under low N conditions, so increasing annual N is best method for long-term control. The temptation is to apply a herbicide now […]
