Pest Profile: Lamb’s Quarters
The stems are erect, 24 – 35 inches high, smooth and longitudinally grooved. They are often red or light green striped. The leaves are alternate, variable in shape, 1 – 3 inches long, stalked, coarsely toothed and covered with white mealy particles, especially on the lower surface. The flowers are small and green, and they are present in the leaf axils and at the top of the stems.
- Late seeding can provide some control because the weed tends to germinate early in the season and its seedlings can be killed through soil preparation or with a burn-off herbicide prior to seeding.
- Plant to narrow rows and with higher seeding rates to increase crop competition.
- Because the plant's seeds persist in the soil, removing escapes before seed set is useful for long-term management.
