Shock horror! Natural selection true!

Just fancy that. A survey of farmers and their weeds has come up with some fascinating results.

Bill Johnson, a Purdue University associate professor of weed science, said farmers who plant Roundup Ready crops and spray Roundup or glyphosate-based herbicides almost exclusively are finding that weeds have developed resistance. It is only a matter of time, Johnson said, before there are so many resistant weeds that the use of glyphosate products would become much less effective in some places.

“We have weeds that have developed resistance, including giant ragweed, which is one of the weeds that drove the adoption of Roundup,” Johnson said. “It’s a pretty major issue in the Eastern Corn Belt. That weed can cause up to 100 percent yield loss.”

So, let me get this straight. You repeatedly subject a living, reproducing organism to a particular environmental stress, and it evolves so as to adapt to that stress? Well, I’ll be.

The best part:

“Monsanto, the maker of Roundup, funded the survey. … [T]he next step is studying the differences among management strategies in grower fields to see which will slow the build-up of glyphosate resistance.”

“Warty vegetable comes to the rescue”

It looks like a wart-covered zucchini and has an equally unappetising name, but experts say it could help rescue the world’s population from malnutrition and disease.

You can’t always trust a journalist to get it absolutely right, but the above quote does seem to be heaping the manure on just a bit too high. The new boss of the Asian Vegetable Research and Development Center is in Australia talking up his book, which includes the bitter gourd or bitter melon, Momordica charantia. He’s full of sensible advice to Australians, to whit:

“The take-home message for Australians is to eat as many varied vegetables as you can – different colours, orange, green – and make sure you have them in balance with the rest of the diet. … cut back on some of the meat consumption, have less carbohydrates and increase the fruit and vegetable intake, then you will live a longer and healthier life”.

But what kind of a lede would that make?

Thanks Dirk for the tip.

Bush wild tomatoes

Someone called James Sultana emailed us to ask: “Where can get some bush wild tomatoes”.

I was forced to reply in pedant mode:

Could you be a little bit more specific? What do you mean by a “bush
wild tomato”? A wild relative of the tomato? Or some other species
(maybe Australian?) that goes by that name?

Alas, Jim hadn’t entered his email correctly in our contact form, so my reply bounced right back. So, if you’re reading this, Jim, answer the question and we’ll do our best to help. And the rest of you, what might a “bush wild tomato” be?
