Fast, effective post-emergent weed control in field corn.
Corn
HOW DOES CALOVOR® HERBICIDE WORK?
Auxins are plant growth hormones
Diflufenzopyr interrupts auxin transport, so auxins can no longer move normally through the weed
This causes natural plant auxins and synthetic auxins like dicamba to accumulate at growing points, increasing weed control
