Cheat |
|
| COMMON NAME: | Cheat |
| SCIENTIFIC NAME: | Bromus secalinus L. |
| TYPE: | Annual Cool-season Weedy Grass |
| DESCRIPTION | |
Germination: |
August to November. |
Reproduction: |
By seeds late May to mid-June. |
Stems: |
Erect, 12 to 24 inches. |
Leaves: |
Both blades and sheaths, smooth or slightly hairy. |
Flowers/ |
4- to 7-flowers per
spikelet in upright panicle. |
Fruit: |
Seed units have palea and lemma attached, with awn on lemma about the same length as seed (1/8 to 1/4 inch). |
FOUND: |
Cheat is primarily found in wheat fields and fence lines. Major problems develop in fall planted alfalfa following wheat. In established stands, cheat is not a major problem. Seed production is limited since the first cutting of hay removes the cheat before it can mature seed. |
CONTROL: |
In seedling stands, good control of cheat can be obtained with early fall application of KERB, POAST PLUS, and SELECT. In established stands, treatments with residual herbicides like VELPAR and SINBAR (0.5 lb/A active ingredient) have been effective when applied January to February. |
