• Erratum: In the February issue, a picture of submersed plant vegetation was placed next to the announcement of the aquatic herbicide Stingray® (carfentrazone). It was brought to the PIO’s attention that Stingray is used for treatment of floating or emergent aquatic vegetation. We regret any confusion.
