Evolution strikes back

Ford Denison drew attention to this astonishing photograph of giant ragweed 1 lording it over a crop of harvest-ready maize.

Weed-resistant giant ragweed Ambrosia trifida

Nothing unusual about that — being a giant anything gives you a licence to lord it over lowlier things. The point, of course, is that the corn crop is Round-up ready and so, of course, is the weed. More facts and figures at The International Survey of Herbicide Resistant Weeds.

Ford also pointed to an interesting discussion on the difficulties of defining anything as slippery as farming philosophy by talking about what is and isn’t permitted.

To give the consumer a clear, black and white choice, organic marketing strategy offers a black and white world where all human-made pesticides and fertilizers, and all genetically modified crops are bad, regardless of their value to farmers or to sustainability. Even limited use is prohibited because it would blur the marketing lines.

Amen. Although let’s not forget that good old-fashioned soft soap is as human-made as anything. In the old days, I always advised beginning allotmenteers to blitz an unkempt plot with glyphosate and then get as holy as you like about being organic. Nothing is more soul-destroying than discovering couch grass or ground elder infesting the asparagus and strawberry beds. Of course, today, it might take more than glyphosate.

  • For UK horticulturalists in need of cash. Wonder if that includes the rosemary collection.
  • I’m pretty sure it doesn’t include AVRDC.
  • Who would no doubt agree with Mark Lynas that “No-one disputes that a balanced and nutritionally-adequate diet is the best long-term solution to vitamin A deficiency and malnutrition in general.” And be as puzzled as the rest of us for the relative lack of funding for research on such a diet.
  • A discussion of why mainstream agricultural science hasn’t got the message across about SRI, courtesy of Facebook. Yeah well, the whole concept of basing interventions on, you know, evidence, is not exactly mainstream. Just ask the balanced and nutritionally-adequate diet guys.
  • Bees are stressed out, the poor things.
  • Creative Commons graphs on changes in vegetable nutrient content.
  • Not all plant viruses are bad.
  • Pat Heslop-Harrison talks DNA, with his usual extraordinary fluency, from 11 mins in.
  • Plant Cuttings! Everything from the botany of food to transcription factors for C4 photosynthesis.
  • Cow genebank proposed.
  • IFOAM gets a TIPI. Vandana Shiva no doubt ecstatic.
