Dicamba cutoff date reminder

The Office of Indiana State Chemist (OISC) would like to remind all agricultural applicators that there is a June 20 cutoff date for applications of most ag-related dicamba products in Indiana.

More from this section

On March 2, the Indiana Pesticide Review Board (IPRB) voted unanimously to classify all Restricted Use Pesticides (RUP) containing more than 6.5% dicamba as Highly Volatile Herbicides (HVH).

A HVH is defined in state law as any herbicide capable of emitting vapors that may cause serious injury to desired plants by reason of movement of the vapors from the area of application of the herbicide to areas inhabited by the desired plants. The IPRB has determined that dicamba herbicides used in agriculture during periods when many non-target plants and crops are actively growing and particularly sensitive to low levels of dicamba exposure meet that definition.

The list of HVHs includes all herbicides containing more than 6.5% dicamba active ingredient and classified as a Restricted Use Pesticide (RUP) in Indiana.

In addition, the HVH determination will prohibit the application of all dicamba RUP herbicides to all crops for the period June 21 through Aug. 31.
