More On Herbicide Resistance

Farmers have been asking many questions about herbicide plans for 2014.  I found a new quiz on herbicide resistance after watching a YouTube that was linked to me.  You might take this quiz first to generate some more questions.

What have you used?  Which weeds are getting more difficult to control?  What strategies should we use to attack this problem, not knowing what 2014 is going to be like?

Probably the biggest lesson I've learned is to spray more often.  Most herbicidal effects only last 30 days at most.  Many do not last that long due to poor spraying conditions or the many things that can make a spray application not effective.

There is no one magic herbicide or herbicide plan.  We must know our weed problems and our program to select the better products and apply them in a timely fashion at the right rate in the proper spray mix.  Application is so important you must have a license to spray for others.  I imagine we all need to study labels more and ask more questions, like this thread suggests.

Weed control is finally coming to the forefront again as old programs aren't working.  The Ohio State weed survey last year showed an increase of weed pressure every year since the study was started.  Out of thousands of fields surveyed, our local area only found 2% of fields weed free, the worst result since the study was started!

We really need to plan out our weed control.  What we have done the past few years is not working!

Google won't post my weedy picture this morning so imagine your worst weed problem, please!  I have to mention I saw the light of Christ in a man we met yesterday.  God bless Ramone!  Maybe we can talk more about that later.

  1. Group one herbicide resistant wild oats have come to my farm a few years ago. By the time I realized what I had it was taking a huge bite out of crop yields on one field. Using herbicides from the same group year after year is the cause. I have had to move up to Group 2 herbicides which limits my crop choices somewhat. We need to rotate our herbicides, just like our crops.

  2. Good job, Ralph, we all must do this!

  3. On the rye going out early with 24d and generic prowl.

    Then when the rye is bigger gramoxone, sencor, and fierce

    come back with classic, prefix 21 days after emergence.
