Tremendous progress has been made in IVM and in more eco friendly
herbicides in the last 16 years.

      A one-time application of such a virulent herbicide as Tordon without
      follow-up is irresponsible. Given that the application was made 16
      years
      ago, I suspect that Tordon's effects were not as commonly known at
      that
      point. I'd also add that the practice of herbicide application as a
      management technique was not as common 16 years ago as it is today
      and
      the necessity for follow-up was often equally misunderstood.

      All this study shows is that man is prone to making mistakes and that
      those mistakes can have grave consequences. It doesn't show that
      avoiding general spraying is right, it shows that the misuse of an
      herbicide is wrong. The problems associated with "the use of general
      spraying as a weed-control technique" are human-derived. This study
      supports why land management activities need to be carried out by
      professionals who understand the need for a thorough, intelligent,
      and
      committed approach.

      Science can never prove something to be right, only highlight when
      something has failed. "No amount of experimentation can ever prove me
      right; a single experiment can prove me wrong." Albert Einstein

      I will gladly repeat and repeat: "I hereby eternally swear that I
      shall
      eschew irresponsible methodology and application in weed-control
      techniques."

      AT LAST!  But SIXTEEN YEARS to declare the obvious that can be
      demonstrated by one simple experiment?

      Actually, I'm not surprised. But let us all repeat and repeat: "I
      hereby
      eternally swear that I shall eschew the use of general spraying as a
      weed-control technique."

      This is not to say that direct application of the minimal lethal dose
      by
      wick, by brush, by injection, by highly directed, low-pressure
      pneumatically-driven application to target plants only should be
      abandoned.
