Rescuegrass |
|
| COMMON NAME: | Rescuegrass |
| SCIENTIFIC NAME: | Bromus catharticus Vahl |
| TYPE: | Annual Cool-season Weedy Grass |
| DESCRIPTION | |
| Germination: | September to October. |
| Reproduction: | By seeds May to June. |
| Stems: | Erect is up to 40 inches tall. |
| Leaves: | Blades 8 to 12 inches long and 3/8 to 1/2 inch wide, rough or sparsely hairy. |
| Flowers/ Inflorescence: |
An open drooping panicle, 3 to 10 inches long, spikelets 4- to 9-flowered and laterally compressed, lemmas mostly awnless. |
| Fruit: | Seed unit with lemma and palea, essentially smooth and no hair. |
FOUND: |
Rescuegrass is found in yards, roadsides, pastures and alfalfa fields. When plants are harvested or grazed, they may continue to be vegetative and produce forage into the summer and fall. |
CONTROL: |
In seedling stands of fall-planted alfalfa, apply POAST PLUS or SELECT in the fall (October to November). In established stands, good control is obtained with residual herbicides such as VELPAR and SINBAR, applied in January-February. In the western 1/3 of the state, rescuegrass can be controlled slightly better with VELPAR than with SINBAR. |
