The Environmental Protection Agency has expanded the label for Callisto herbicide from Greensboro, N.C.-based Syngenta Crop Protection to include 14 additional crops, including blueberries, lingonberries and rhubarb.


The broadleaf herbicide, which contains the active ingredient mesotrione, was originally registered for corn in 2001.


Mesotrione, which is an HPPD inhibitor, is systemic and is absorbed by the weed within the first 24 hours of application, according to a news release.
