| Hate to bring a little logic to the herbicide resistance fun but I’ll try. Need a bit of history.
Before roundup, fields got a mix of chemical families and a cultivator to keep them clean. Roundup came and people saw it killed 99.7% and was cheap. So the only chemical used was roundup. And every year for the first 10 you didn’t notice the .3% that had some sort of natural resistance. But the seed bank changed over time, the 99.7% seed bank is gone and we’re left with the .3% seed bank that we started with but also a massive seed bank built up by only using roundup and letting those few survive every year. Now do the same for glufosinate. Glufosinate killed 99.7% and roundup was a waste of money so let’s just hit it with glufosinate or Dicamba or 2,4D. Then change up that order depending on farmer preference as each herbicide became less effective on their seed bank. All of a sudden the only weeds reproducing are resistant to all of them because we naturally selected them and utilized one herbicide instead of a broad spectrum approach. If your tank mix is simple you are part of the problem. I’m sorry to say it but that’s the truth. Just start praying bur-cucumber doesn’t become one of those resistant monsters in the next 10 years because of the same mentality. BTO neighbor quit doing anything crazy on weed control. Corn gets atrazine and roundup post plant and he’s one pass and done, it’ll be what it’ll be apparently. Better get the cultivators out of the fence rows and tune them up, or hope there’s some new miracle herbicide coming soon. | |

Dicamba epic fail
