Posted 29 June 2006. Forage and Grazinglands. SDSU Publication: Small Grain Forages and Herbicides South Dakota State University. Brookings, SD (June 8, 2006) - A new publication from South Dakota State University offers important reminders about harvesting small grains for forages after they've been treated with herbicide. SDSU Extension Extra ExEx8156, "Restrictions for Harvesting Small Grain Forages After Herbicide Applications," is available online. Or ask at your county Extension office.
Written by SDSU Extension Weeds Specialist Mike Moechnig and SDSU Extension Integrated Pest Management Coordinator Darrell Deneke, the two-page publication lists the waiting period required after herbicides have been applied before small grains can be harvested for hay, forage, or grazing. Information for 32 different small grain herbicides is included. "After unforeseen circumstances such as an extreme drought, you may be considering the option to harvest small grains for forage or hay," Moechnig said. "However, the decision to utilize a small grain crop for forage may be limited by restrictions associated with herbicides already applied. These restrictions may protect the health of livestock or minimize human exposure to the presence of herbicide residues in meat or milk. In some cases, the restrictions are established as a security measure due to a lack of data regarding the persistence of herbicide residues in animals." Consult the SDSU publication, as well as the specific herbicide label, for more information, Moechnig advised. Contacts: Mike Moechnig |
