All winter I have been talking about Reflex as a tool for managing Palmer amaranth and other problem weeds. Farm articles from the southern US often discuss this product as well. It is commonly used for snap beans and soybeans. But it is one of those products with unique regional restrictions. On Delmarva, we are limited to one application every two years, and a maximum use of 1.5 pts. South into the Carolinas and Georgia, they can use higher rates and use it every year. North of Delaware (Pennsylvania and New Jersey) it is limited to one application in alternate years with a maximum use rate of 1.25 pts. So be sure to plan your herbicide rotation accordingly.
