Monsanto has obtained supplemental labeling for preharvest application of Roundup PowerMAX herbicide and RT3 herbicide on oilseed crops [such as Borage, Canola, Crambe, Cuphea, Echium, Flax (seed), Mustard (seed), Rapeseed, Safflower, and Sunflower] that is valid through the 2017 growing season.

Preharvest Glyphosate on Oilseed Crops

Monsanto has obtained supplemental labeling for preharvest application of Roundup PowerMAX herbicide and RT3 herbicide on oilseed crops [such as Borage, Canola, Crambe, Cuphea, Echium, Flax (seed), Mustard (seed), Rapeseed, Safflower, and Sunflower] that is valid through the 2017 growing season. This use was first approved by the U.S. EPA in June 2013. This supplemental labeling will allow oilseed growers to make preharvest applications this year and allow more time for Monsanto to incorporate this preharvest use information to the main label that will be released. This label has been registered in North Dakota. For those in surrounding states be sure it is approved in your state. Always read and follow label directions.

Note: Paraquat is not registered for preharvest use in wheat. Use in this manner would be considered off-label and the applicator may be subject to fines and quarantine of the wheat crop.
