James Kennedy on Chemistry

 

 

Sometime in the last twenty years or so, the word “chemical” has become a dirty word.  Hard to pronounce words. Unnatural synthesized substances. Mad scientist concoctions brewed in a laboratory.

I used to try to introduce some perspective when I facilitated pesticide workshops for the general public by teaching how scientists and regulators determined toxicity, so comparisons between familiar substances, like caffeine, aspirin, or detergents could be made, to varying degrees of success.

It was the “unnatural synthesized substances” part that I had the most difficulty overcoming.… Continue reading this article “James Kennedy on Chemistry”

Show me the data!

One of my favorite bumper stickers from days gone by said simply “Stop Continental Drift”. Good luck with that.

stop_continental_drift_530

Today’s topic deals with another type of drift – a phenomenon one of my professors referred at ‘Bibliographic drift’.   This type of drift occurs when authors cite a paper without bothering to look up the original source.  Then a second author cites original source based on the first author’s paper; then a third author cites it based on the second paper and so on and so forth. … Continue reading this article “Show me the data!”

Odie

One of the coolest plants you’ll ever see is the titan arum. It varies quite a bit in height, but this one, named Odie, measured just a little over five feet tall. This amazing corm bloomed at the UNC Charlotte Botanical Gardens last week. Unfortunately the bloom only lasted for about two days, and during that time the area around it smelled just like roadkill. We are now waiting to see whether a fertilization attempt was successful.… Continue reading this article “Odie”

Ask an Entomologist

No, I’m not one.  But the folks who run the Ask an Entomologist site are.  You can ask them anything about bugs, and some of their best posts result from questions that come from kids.

Don’t think of it as a place for identification, although they’ll do their best to answer, or direct you to a good place where that can happen; think of it as a way to prompt them to explain some aspect about the science of Entomology that may not be well understood by the general public.… Continue reading this article “Ask an Entomologist”

Spring vs. Fall planting: Where you stand depends on where you sit

I’m reviewing some literature while working on a proposal and ran across a paper by Lisa Richardson-Calfee, Roger Harris and Jody Fanelli at Virginia Tech on the effects planting date on sugar maple trees.  It’s not actually the topic of the proposal I’m working on but the paper caught my eye because spring versus fall planting is one of those questions that just never seems to go away.  In this particular study, balled-in-burlap trees planted at spring budbreak had more new root growth than trees planted in the fall. … Continue reading this article “Spring vs. Fall planting: Where you stand depends on where you sit”

The Heat is On!

We are in the dog days of summer! Record high temperatures across the country have been reported. Let’s face it, climate change is real and the planet is getting warmer, despite record cold temperatures in winter in some areas. With climate change, there are more occurrences of extreme temperatures as well as precipitation such as severe drought, flooding, heavier than usual snowfall, etc. So, how does climate change affect gardeners? To understand the concept, we must first understand how high temperatures affect plant growth and development.… Continue reading this article “The Heat is On!”

An Open Letter to Consumer Reports

Dear Consumer Reports,

A good friend of mine, Linda Chalker-Scott, recently reviewed some of your recommendations on weed control and found them wanting. I concur with Linda’s assessments, but I feel the need to take her critiques a bit further because:

#1 The article that Linda reviewed made a recommendation which is not only questionable in terms of its efficacy, but also its safety.

#2 You recently published another article on a very similar topic which is misleading.… Continue reading this article “An Open Letter to Consumer Reports”

Extension….Again

About 6 months ago I wrote a little article about what I perceived to be the most significant problem within extension, which is that extension personnel, and specifically tenured and tenure track faculty, simply don’t receive recognition or credit for accomplishing their job. In this essay I’m going to give a specific example of this problem.
Normally, when someone does what they are assigned to do, they are rewarded, or at least an acknowledgement is made that they are performing satisfactorily.… Continue reading this article “Extension….Again”

Stuck in the middle with you

Clowns to the left of me,

Jokers to the right, here I am,

Stuck in the middle with you

 

More than once in the past couple months I’ve come close to pulling the plug on FaceBook.  What started as a fun and easy way to keep up with family and friends back home and stalk old girlfriends has devolved into an infinite do-loop of whininess, acrimony and vitriol over GMO’s, organic food, vaccines, and President Obama. … Continue reading this article “Stuck in the middle with you”

Go sport fishing at your local nursery

Regular fishing, for actual fish, is quite possibly the second most boring think ever invented (First place, of course, goes without question to baseball) but sport fishing! Now THAT is something I can get behind.

By sport fishing I mean, of course, looking for sports – chance mutations – in plants. Sometimes a flower color changes, or sometimes a leaf becomes variegated, like on this lilac branch I found at a friend’s nursery a couple years ago

Nurseries are great places to go “fishing” for these sports, simply by walking down the rows of plants looking for anything odd or out of place.… Continue reading this article “Go sport fishing at your local nursery”
