Conversations among family and friends this week could include dying, hiding and finding "eggs." It is Easter you know. 

 

The eggs that we are talking about in this BYGL Alert are those of the gypsy moth (Lymantria dispar).  After spending about nine months in the egg mass stage, warmer temperatures are triggering the hatch of the caterpillars in Ohio.  These tan almost felt-like in appearance masses that can be laid anywhere will soon be bursting with 1st instar caterpillars. 

While we are eagerly awaiting the first hatch in NW Ohio,...

 

This Turf-Tip was provided Joe Rimelspach and Todd Hicks with OSU – Plant Pathology and Turfgrass Program.

 

Of the four seasons, this is the “third best time” to seed a lawn. The best is autumn, then winter, followed by spring and the least desirable time is summer. The main challenge with the spring seeding is the large number of weeds (both grassy weeds and broadleaf weeds) that can come up with the grass seed. Seed as early as possible in the spring so new plant can develop a root system before summer heat and dry conditions...

 

Earlier this week, Pamela Sherratt, Turfgrass Specialist in the Department of Horticulture and Crop Science at The Ohio State University alerted Extension to the potential of some questions coming into the Extension offices about a product, Roundup for Lawns from clientele across the state.    

 

A walk through the aisles of the pest management area of a garden center this spring may cause some consumers to take a second look. While Roundup has been around for a long time, Roundup for Lawns is a new product that has recently hit the shelves. The same name and...

I found Elm Leafminer Sawfly (Fenusa ulmi) adults flying around their namesake host yesterday in southwest Ohio. The emergence of this leafmining sawfly was predicted in my part of the state by accumulated GDD (219) and phenological indicators such as the full bloom of common chokecherry. This also means there is little doubt that Birch Leafminer Sawfly (F. pusilla) and Hawthorn Leafminer Sawfly (Profenusa canadensis) adults are on the wing.

I came across an infestation of Juniper Scale (Carulaspis juniperi, Family Diaspididae) Sunday while doing some unconditional pruning (e.g. whacking back!) of junipers in the Boggscape. The discovery provided great samples to share, examine, and discuss with participants in the first 2017 Southwest Ohio BYGLive! Diagnostic Walk-About held yesterday at Spring Grove Cemetery and Arboretum.

The starting point for yesterday's Southwest Ohio BYGLive! Diagnostic Walk-About held at Spring Grove Cemetery and Arboretum was inadvertently located in the middle of a very busy ground-nesting bee bailiwick. This sparked an impromptu discussion on the behavior and importance of these native pollinators.

In architecture,  a term often used is form (ever) follows function.  This was coined and practiced by the 20th century U.S. architect Louis Sullivan and inspired, for example, Frank Lloyd Wright.

 

  A loose form of this emerged during a recent class trip for the Horticulture and Crop Science 3410 class (Sustainable Landscape Maintenance). We had just visited the wonderful “Building Ohio State: From Forest to the Renovation of Thompson Library” exhibit on the first floor of the magnificent OSU Thompson Library (exhibit until May 14) on the Main Campus in Columbus...

I was amazed yesterday at the prolific handiwork of Burrowing Crayfish in the Voice of America (VOA) MetroPark in Butler County located in southwest Ohio. Hundreds of their unusual looking mud structures were rising from the soil in turfgrass and naturalized areas.

If you've traveled Ohio's southern interstates lately, particularly on I-71 between Columbus and Cincinnati, you may have hummed a Hendrix tune or felt like riders of the purple sage as you drove past farm fields bathed in a deep purple hue.

Each month, the United States Department of Agriculture's (USDA) Animal Plant Health Inspection Service (APHIS) updates and distributes an Emerald Ash Borer (EAB) (Agrilus planipennis Fairmaire) Detection Map. While EAB is "old news" to many in the buckeye state, it is interesting to continue to watch the progression of this invasive species in North America. In February 2003, EAB was confirmed for the first time in Ohio in Lucas County in NW Ohio, approximately seven months after the initial detection and identification in Michigan the summer before. Fast forward 14+ years later...
