Pest Profile: Redroot Pigweed
Plants have a long, fleshy, reddish to pink taproot and stems that are erect, light green, branched, 23-35 inches high, rough and angular. The leaves are alternate, stalked, dull green, oval-shaped, rough and 3-4 inches long. Plants have numerous flowers that are small, green and crowded into dense, finger-like spikes.
- Redroot pigweed seeds prefer warm temperatures of 20ºC or higher for germination.
- Crops established before soils warm and weather sets in are very competitive with this weed.
- Watch growth stages carefully under hot conditions because the plant can quickly advance beyond the recommended stages for herbicide application.
Please read each label to determine which herbicide is appropriate for the crop affected.
