East Central Arkansas | First off a disclaimer. I am just a old retired farmer that did his own spraying. Small acreage so I was able to do things different than most folks.
Your location and the growth stage of what you are spraying makes a difference. Your weather conditions before and after spraying as well as moisture conditions. How thick the growth of weeds is. Some of those Winter weeds come up thick here and really cover the ground.
My spraying of dicamba was in the late Fall to very early Spring. I think like 8 oz a acre was the most we used. People around here didnt use it post on corn so we had never really seen the problem it caused on soybean crops. We were mainly cotton farmers and 2,4D is to cotton what dicamba is to beans so we werw reluctant to put 2,4D in our sprayers.This was before the dicamba tolerant soybeans and cotton was introduced. So before all the problems that came with spraying the dicamba in those crops.
Back then I don't know if there was even volatile products readily available but we did use some drift and mist control products at times.
For drift control using the right tips and pressures for the water rate needed is important and the chemical label will give you that info. Read and study labels. Get the charts for your tips. Know what size drops you are spraying at what pressure. Just because your tip is right at 8 mph doesn't mean it is at 15 mph. | |
