The view from Monsanto:

Showing how the number of resistant weeds has exploded. And that is supposed to reassure us?

    @Lee – I believe the chart you pulled off the weedscience.org home page is for all resistant weeds to all classes of herbicides. There are more than 300 resistant weeds. That graph shows that herbicide-resistant weeds are not new.
    What may be more helpful is this chart from the same website:

  • This graph lists the number of resistant weeds by the type of herbicide. You’ll note that the blue line represents glycines, which is the category of herbicide that glyphosate-based chemicals (including Roundup) fall into. This category includes less than 20 weeds. The majority of the weeds in the graph you linked to earlier are resistant to other classes. So, there are around 280 resistant weeds to other herbicides.
It seems to me that there is a herbicide problem in the offing, much like the human antibiotic overuse leading to resistance.

"Starting in 1996, farmers began to plant Roundup Ready corn, soy, and cotton across millions of acres of farmland without restriction."
So it took 5 years for roundup ready resistance to develop in weeds.

Looking at the second graph it appears that the vertical scale is resistant biotypes. - so if a glyphosate only kills 20 biotypes then it has hit full resistance as shown by the flattening of the line.

It would have been more constructive to have a % of biotypes resistant out of biotypes killed as the vertical scale.

Hmmm! do we need to think of what we are doing to the planet?
