Dr. John N. Rogers, III
Michigan State University
As summer comes to a close aeration season begins on golf courses. Follow this link to an article originally published in Golf Course Management reviewing research conducted at the Hancock Turfgrass Research Center on the effects of hollow-tine diameter and topdressing incorporation implements on sand topdressing integration.

5.
A combination of lightweight rolling and sand
topdressing programs to decrease pesticide inputs and enhance fairway turfgrass
quality
6.
Anthracnose control on greens and fairways
7.
Poa annua control on putting greens
8.
The new
Schwartzkopf Field Laboratory and phytohormone responses to Primo application
Lawns and Athletic
Fields Research Tour
1.
Spray nozzle dynamics and selection for optimal
pesticide efficacy
2.
Nutrient runoff following fertilizer
applications
3.
Necrotic Ring Spot cultural and fungicide management
programs
4.
National Turfgrass Evaluation Program Kentucky

and player safety
6.
New herbicide technology for goosegrass,
crabgrass, and nimblewill control in cool-season turf
7.
Postemergence crabgrass control
8.
Insecticide and cultural recommendations for
minimizing grub injury
Afternoon Workshops
(12:30-2:30 pm)
1. Disease Walk
The MSU Turf Pathology research team will lead this
diagnostic tour for pathogens at the turf center. If you have difficulty distinguishing
between Laetisaria fuciformis and Limnomyces roseipellis on your golf
course you definitely need to attend this workshop. Participants will learn:
1)
How to identify the common turfgrass diseases
using both in-field techniques and microscopes
2)
Management options for common diseases
including: dollar spot, brown patch, crown-rotting anthracnose, red thread, and
pythium blight and root-rot.
3) How
to recognize the symptoms of summer decline of both bentgrass and Poa annua
2. Weed Walk
As the weed walk enters it’s lucky 13th year, the
summer of 2012 left some tremendous voids in the turf where weeds were more
than happy to fill in. You’ll tour the
turf center and learn identification characteristics of the common turf weeds
and the best control practices. Tour
will include discussion of best management practices both with and without
herbicides to ensure high turfgrass quality and most importantly customer
satisfaction.
3. MSU Athletic Field
Tour (on Campus)
The athletic field tour will visit three sites on the MSU
campus to learn about new field establishment and compare two synthetic turf
fields. The field at the DeMartin Soccer
Complex was killed following the conclusion of the fall 2012 season and seeded
to Kentucky bluegrass on May 13, 2013.
The previous field was contaminated with Poa supina and the desire to
have a uniform turf stand capable of withstanding all season use was the
primary goal. Establishment practices
for a summer seeding will be discussed including mowing, irrigation, and pest
management.
Following the visit to the DeMartin Soccer Complex the tour
will stop by the football practice field which is in the process of installing
a new infill synthetic practice field, scheduled to be completed about a week
before field day. The construction and maintenance of the infill synthetic
field will be discussed.

Top 5 Reasons it’s an Epic Crabgrass Year
Dr. Kevin W. Frank & Aaron Hathaway
Michigan State University
I was recently asked by a lawn care operator to reply via email with 1000 words or less of why it’s an epic crabgrass year, well maybe he didn’t say epic but you get the idea. I accepted this challenge heartily but decided in the spirit of today’s world of texting and twittering to do it in less than 100 words.

1. Record heat and stress in 2012 resulted in
bumper crabgrass crop, plenty of seed, and thinned turf for more opportunities
for crabgrass to invade this year.
2. Cold, long spring delayed crabgrass germination,
may have escaped early spring preemergence applications.
3. Soil moisture increases soil biological
activity, in turn, increasing herbicide degradation.
4. Plentiful precipitation in June when young
crabgrass was geminating helped with root development.
5. High temperatures in July were perfectly timed
for crabgrass to really start competing.
