2. Lagoons, levees, seeps and sinkholes
3. Canals, drainage and irrigation ditches, strip pits
4. Wildlife Management Habitats (wetland areas)
Methods:
A. Calibration
Most products applied with handgun or backpack sprayer (see EPG 821.11 for calibration of hand sprayers)
B. Recommended products and rates
Table 821.21 Recommended Products and Rates for Aquatics or Near Streams or Open Water
| Herbicide | Broadcast Rate | Handgun Rate | Comments |
|---|---|---|---|
