Nobody in their right mind considers pesticides safe. They are, after all, poisons which we have created to kill things, be those things plants, insects, fungi, rats, or whatever. The idea that we could have foods with no pesticides on them is attractive. Now I’ve got to admit that, as a general rule, I don’t think that the levels at which most pesticides are found on foods is concerning. Our methods of detecting poisons are just too sensitive today and so we end up saying that a poison is “present” on a tomato or whatever even if it’s there at a harmless parts-per-trillion level. … Continue reading this article “Dirty Dozen?”

Duty Calls
As retirements have decimated our Horticulture Department’s faculty ranks, I find myself in the interesting position of teaching a course in small fruit production next fall semester. I’m working on the syllabus as was speak (hence this post). If you’ve read my bio (“About Us”), you’ll see that this is not my bag. But our students are clamoring for fruit and vegetable production courses, so someone’s got to do it. We are also currently without on-campus vegetable faculty, if you can believe it.… Continue reading this article “Duty Calls”
Visiting Professor guest post: Organic foods
There are lots of reasons consumers give for buying organic foods, but a few reasons are very common. Among them is the notion that organic foods are better for you. Really? Are organic fruits and veggies better for you? Depends on what you mean by ‘better for you’. But as far as we know, the answer is probably ‘no’, especially if you’re buying organic fruits and veggies (F&V) at the store. It might seem crazy, but there’s no good evidence to support the notion that you will be more healthy by shopping for organic F&V. … Continue reading this article “Visiting Professor guest post: Organic foods”
A Dangerous Game
Every once in awhile I become infatuated with some idea and can’t stop for looking for information on it. It usually starts when I want to find a good quote for a particular article or column that I’m writing and then ends up swallowing two or three days. Well, it happened to me again yesterday and spilled over into today. I’m currently finishing up a project with an old friend of mine from college who happens to be a political science professor at the University of North Carolina Charlotte. … Continue reading this article “A Dangerous Game”
Organic or local?
I grew up on a small farm (30 or so acres) near Tacoma, Washington. We raised our own Herefords, I gathered eggs from my frizzle chickens, and we all enjoyed apples, plums and cherries from our fruit trees. Neither of my parents were farmers by profession, though my grandfather owned a dairy farm in Oregon. Eventually, my husband and I hope to move back to the family farm, if for no other reason than preserve it from the surrounding encroachment of houses.… Continue reading this article “Organic or local?”
You say tomato, I say phytochrome
Yesterday I got an interesting email about a new product – a Tomato Automator. Briefly, this square, red plastic disk slips around the stem of a tomato plant to suppress weeds and pests. Most intriguingly, we’re told that the color “triggers a natural plant protein that makes tomatoes mature faster and product more fruit.”
Given this is a red product, it’s likely that the protein referred to is phytochrome (literally, “plant pigment”). Phytochrome activity is maddeningly complicated to explain, so we’re going to keep this simple and refer (somewhat inaccurately) to “active” and “inactive” forms of phytochrome. … Continue reading this article “You say tomato, I say phytochrome”
My Favorite Drug
I love coffee, but I’m not a big coffee drinker. On average I probably consume a cup of coffee every week or two. Why don’t I drink it more often? For a few reasons: First, I’m too jumpy/jittery/nervous to begin with and I don’t need this stuff making it worse, second, it tends to upset my stomach if I haven’t had a meal beforehand, and third, while I like regular coffee, the stuff that I really love are those insane fru-fru coffee drinks that you can only get at specialty shops for five or six bucks — which seems like a waste of money to me. … Continue reading this article “My Favorite Drug”
Peanuts
I’m not from the South, and so I can’t call myself a Southerner like Holly can, but I did spend 6 years in Georgia. There are lots of things about it which I miss: winters which are more like a Minnesota fall, the almost disgustingly friendly people (OK, there was that one time that I was chased by a guy with an SKS assault rifle — but that was an exception — generally Southerners are the nicest people you could ever want to meet), and, especially, the food. … Continue reading this article “Peanuts”
Eat your veggies! (But not the arsenic, or the chromium, or the lead…)
The last few years have been a perfect storm for the resurgence of home vegetable (and fruit) gardens. Grapevines are trellised along sidewalks, herbs replace the grass in parking strips, and tiny gardens of carrots and lettuce are shoehorned into any available spot. It’s all good – but we need to be particularly careful about what those plant roots might be taking up along with nutrients and water.
1) Contaminated soil. Many urban (and suburban, and even rural) soils are contaminated with heavy metals, pesticides, and/or industrial wastes. … Continue reading this article “Eat your veggies! (But not the arsenic, or the chromium, or the lead…)”
Organic food study creates uproar
I’ve already done my blog for the day, but am hoping this story might fuel another discussion. There are some very good reasons for buying/eating organic food, but nutritional superiority does not appear to be one of them. http://seattletimes.nwsource.com/html/localnews/2009599887_organicstudy05m.html
