Overwintered Calico Scale Females are Puffing Up and Dripping Honeydew

Overwintered calico scale (Eulecanium cerasorum) females are now "puffing-up" and pumping out impressive quantities of clear, sugary honeydew in southwest Ohio.  This is a non-native "soft scale" meaning that mature scales are protected by a soft shell.  The scale's common name comes from the starkly contrasting calico pattern of black-and-white markings on the hemispherical-shaped shells of mature females.  The mature females measure about 1/4" in diameter and their distinct markings make them easy to recognize, particularly on bark and branches that are blackened by sooty mold...

Earth Day Can Be Everyday in the Green Industry

On Friday, April 22, 2016 people across the world will be observing Earth Day.  United State Senator Gaylord Nelson was the founder and organizer of first Earth Day.  Observed beginning in 1970, Earth Day was developed as a day of education about environmental issues.  In 1990, Earth Day went global.  According to the Earth Day Network (EDN), over 200 million people in over 140 nations participate in this observation.  Some areas celebrate not just a single day, but rather an entire week. And the green industry could be recognized for celebrating Earth Day all year long!

From Snow to Sunshine

If you have lived in Ohio for any length of time, you have probably heard someone say, "if you don't like the weather, just wait, because it will change."  There was a big weather change that occurred just over a week ago.  On Friday, April 8 and Saturday, April 9, a storm bringing snow blew through Ohio.  Snowfall totals ranged from minor accumulations, up to 12".  Northwest Ohio seemed to get the brunt of the storm, and Toledo made the national news as the surprising April snow storm caught some off guard.  The snowfall total last weekend exceed any other measurable snowfall totals from...

Spruce - Phomopsis Canker

Branch dieback in spruce can have many causes such as the generalized dieback we see as roots fail from root rot or various root injuries. Cytospora canker is a very well-known disease of spruce, particularly blue spruce (Picea pungens). A dead branch in a spruce is often attributed to Cytospora but that is not always the case as was evident in a recent blue spruce sample.

 

Look closely at the dying branch. Trace the dead and dying tissue back to where it transitions to healthy. Carefully scrape the bark at that transition looking for discoloration of the...

Whether it concerns insects, diseases, plants, mammals or aquatic species there is something out there for everyone! One thing that is true across the board is that early detection is key to dealing more effectively with all of these.

 

As a group of Extension professionals were discussing our new Asian longhorned beetle infestation in 2011 we kept coming back to how do we get these things reported early when they are still on a relatively small scale. We were...

Silver Maple Flower Fascination

Ever wonder why when passing a Silver Maple (Acer saccharinum) in flower, one week the blooms appear to be a green-yellowish cast and then suddenly, a little while later, the blooms appear to have turned red?  Then the questions begin like, did I misidentify the tree or did I really see light yellow blooms on the branches?  First and foremost, you are not going crazy, and in the case of the silver maple, it is perfectly normal to see both colors of blooms!  According to Micheal A. Dirr's Manual of Woody Landscape Plants, silver maple blooms are described as follows: "...

Eastern Tent Cats to Arrive Soon boggs.47 Mon, 03/14/2016 - 16:13
