| My understanding is that several of the unniversities are doing research on yield loss from a 2nd post application of gylsophate & seems there may be something to it. As for my personal experience it's not unusual to see approx 4bpa drop on the yield monitor where we have come back in & spot sprayed gylsophate. This does not include any loss due to wheel track damage. May not be scientific enough for you but I have seen enough over the years to convince me that there is a definite yield loss. | |

To spray or not to spray????
