| Description |
An aquatic invasive non-native plant egeria (Egeria densa Planch.) in Battle Ground Lake (Clark County) was treated with the herbicide diquat in 2003. Plant community and water quality data were collected before treatment and up to three years after treatment. There was a significant reduction in egeria frequency and biomass after the herbicide treatment. The diquat spread throughout the lake and persisted at low levels in the water column for at least two weeks after treatment. There was a slight decrease in surface water dissolved oxygen and water transparency after the herbicide treatment due to increased algae growth. |
