Safe use of Magister
Clomazone (Magister®, Director®) is a very effective herbicide for the control of barnyard grass. Many growers however have avoided using it because of concerns with its potential to damage rice. Rather than excluding clomazone from the list of chemicals considered for grass control, it would be better to know how to safely use it and retain it as a viable and beneficial option.
