We just completed pre and post emergent herbicide applications in our secondary rough areas. A different type of post emergent herbicide was used that actually turns the plants white before they go away. It's taking a little longer then normal for this to happen due to the cooler temperatures.
With the severe slopes where most of the secondary rough is located a hand sprayer with hose is used. This makes the process much longer versus being able to ride on the sprayer when applying.
Our next pre and post emergent herbicide application will be to the primary rough. A different group of herbicides will be used in these areas.
