- an annual weed occasionally found in agricultural fields;
- a mobile irrigation system; or
- a one person submarine?
If you chose a), you’d be right. Waterpod (Ellisia nyctelea L.) is an annual broadleaf plant native to Manitoba. It’s often found in shaded, wooded areas but can also thrive in ditches and agricultural fields. Our wet soils and cool spring must have provided ideal conditions for waterpod emergence as it’s being found in abundance in fields across the province.
The good news is waterpod isn’t much of agricultural pest. Although it’s an annual, it emerges and flowers early and usually dies off in June. It’s also very susceptible to glyphosate and most other burn-off and post-emergent herbicides.
