Henbit |
|
| COMMON NAME: | Henbit |
| SCIENTIFIC NAME: | Lamium amplexicaule L. |
| TYPE: | Annual Cool-season Broadleaf Weed |
| DESCRIPTION | |
| Germination: | August to March. |
| Reproduction: | By seeds March to April. |
| Stems: | 4 to 16 inches tall, slender, smooth, 4-angled, with many branches that are more or less prostrate with ascending tips. |
| Leaves: | Opposite; blades simple, broadly ovate, margins often 3-lobed, surfaces pubescent, upper blades sessile, lower blades petiolate. |
|
Flowers/ Inflorescence: |
In whorls in the axils of upper leaves, pinkish to purple. |
| Fruit: | Calyx surrounding 4 nutlets, tan to grayish-brown. |
FOUND: |
Henbit is found in gardens, cultivated fields, and waste places, especially those with rich soil. It is often found in fall planted alfalfa and thinning stands. |
CONTROL: |
Henbit seldom causes any yield loss since it is not very competitive. Also, henbit matures in early April and is mostly gone by the time of first harvest. EPTAM controls henbit in fall planted alfalfa. In established stands, good control is obtained with dormant applications of herbicides like SINBAR and VELPAR. |
