Terry Davis and Dr. David Smitley provide their annual update on grub control products.
Seems like every lawn is being overrun with these pesky diggers.
Crabgrass is one of the most prevalent grassy weeds found in Michigan lawns. Crabgrass thrives in full sunlight and high temperatures and can easily out compete common cool-season grasses under these conditions.
The MSU Department of Plant Pathology has developed a great web site for identification of turf diseases as well as detailed information and photos of 22 turf diseases.
Japanese beetle larvae can cause serious damage to golf course fairways and occasionally to home lawns. It normally is not a problem of non-irrigated turf.
The European chafer may be the most serious grub pest of home lawns and low-maintenance turf.
The bluedgrass billbug, Sphenophorus parvulus, is a weevil that occasionally causes extensive damage to home lawns in Michigan. These beetles are named because of their long snout or "bill" which ends in a set of small mandibles or jaws. Billbugs in the lawn are generally not detected until the first signs of damage appear in July.
Several factors determine turf survival under water: turfgrass species, submersion duration, submersion depth, water temperature and light intensity.
This report summarizes the 3 year study evaluating 15 natural sports turf sytems on the market. Researchers subjected each field sytem to simulated American football traffic over multiple seasons. Turf cover and surface playability characteristics were determined throughout the season. Soil infiltration rates were measured at the conclusion of each season.
The built-up sand-capped athletic field system is a cost effective renovation process for failing native soil athletic fields. Research designed to address the feasibility of this renovation process has determined that a drain tile spacing of 13 feet apart, combined with a 1 inch sand topdressing layer, can substantially improve athletic field drainage and surface stability, and as much as ½ inch of topdressing sand, applied over a 5-week period, will improve turfgrass stability and wear tolerance. Other highlights include a general overview of the built-up sand-capped athletic field system, a renovation timeline and cost-benefit analysis.
Optimizing Cultural Practices to Improve Athletic Field Performance
The MSU GDDTracker network monitors weather data from Michigan, Indiana, Illinois and Ohio. The database updates each evening with the previous days data and a new five day forecast. GDDTracker includes tools for weed emergence, insect activiy, and application timing for annual bluegrass seedhead suppression.
The non-ag irrigation committee recently completed a document outlining best management practices for non-agricultural irrigation. The BMP document is available for download. Several external irrigation resources are also available here.
Legislation restricting phosphorus use on turfgrass in Michigan became effective Jan. 1, 2012.
• MSU Soil Testing Lab Recommendations for Phosphorus Applications to Turfgrass • Natural Resources and Environmental Protection Act (Excerpt), Act 451 of 1994, Part 85 Fertilizers: Sections pertaining to phosphorus restrictions highlighted. • New Legislation Restricts Phosphorus Fertilizer Application on Turf, article by April Hunt, MDARD • Phosphorus Restrictions FAQ's • Use Phosphorus Free Fertilizer
The MSU Department of Entomology has developed a great web site for identification of turf insects as well as detailed information and photos of 14 turf insects.

Soil compaction, soil layering and excessive thatch buildup are common problems on home lawns in Michigan. Cultivation (also called aerification) is the process of physically modifying the soil by removing plugs from the soil profile.
Integrated pest management (IPM) is a system of managing pests by using a variety of control methods. For turfgrass management, the system is designed to optimize conditions for healthy plant growth because a healthy and vigorously growing lawn can tolerate a higher degree of pest pressure.
Learn key identification characteristics of common and not-so-common turfgrass weeds found in Michigan and the midwest.
Purchasing quality turfgrass seed for reestablishing lawns or establishing new lawns is critical to the future success of the lawn. Several key words often seen on bags of lawn seed are common indicators of what turfgrass species the bag contains.
Kentucky bluegrass is the most widely used turfgrass in Michigan. It is used in home lawns, institutional grounds, parks and athletic fields. The species is persistent and attractive and has a medium to fine leaf texture and medium to dark green color when properly fertilized.
The Buckeye Sports Turf Program was developed to keep sports field managers abreast of current topics important in the management of cool season athletic fields.
