Brett Gates with ODA shared that treatments are administered using a low-flying aircraft that flies just above tree tops just like the photo shared with this article online.  High humidity, low...

Earth Day Can Be Everyday in the Green Industry stone.91 Wed, 04/20/2016 - 21:47

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 stone.91 Sun, 04/17/2016 - 23:06

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 taylor.8 Wed, 04/13/2016 - 10:21

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...

Invasive Species and Smartphone Technology smith.81 Mon, 03/14/2016 - 16:20

Non-native Invasive species issues are commanding a lot of natural resource professional's attention these days. 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 draper.15 Mon, 03/14/2016 - 16:17

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

The accumulated Growing Degree Days (GDD) that predicts eastern tent caterpillar (ETC) (Malacosoma americanum) egg hatch is 92.  Cincinnati has reached 89 GDD meaning that ETC eggs are poised to begin hatching in southwest Ohio.  ETC spends the winter in shiny, blackish-brown egg masses wrapped around twigs on their host plants.  A close examination will reveal that the eggs are encased in a structure that resembles bubble-wrap.

New Book: Invention of Nature by Andrea Wulf chatfield.1 Fri, 03/11/2016 - 10:28

A book review recommendation for all is a wondrous book by Andrea Wulf, titled The Invention of Nature: Alexander Von Humboldt’s New World.    

 

How is this for reviews of this life: “One of the great ornaments of his age.” from Thomas Jefferson.

 

“Nothing ever stimulated my zeal so much as reading ‘Humboldt’s Personal Narrative” from Charles Darwin, and according to Andrea Wulf “…saying he would not have boarded the Beagle, nor conceived of the “Origin of Species” without Humboldt.”

 

Quoting from Wulf...

Spring Cankerworms Appreciate Warm Weather! shetlar.1 Wed, 03/09/2016 - 13:15

As I was walking into one of the offices on The Ohio State University Campus this morning, a small grey-colored moth caught my eye.  Upon closer inspection it was a male of the spring cankerworm, Paleacrita vernata (Lepidoptera, Geometridae)!  After my meeting I walked around the building and quickly spotted one of the females, also on a wall. The females are unusual in that they have no wings.  They look like little fuzzballs!  The females release a pheromone which attracts males for mating.  Soon after mating, the females attach eggs, usually onto potential host trees, mainly...
