In battle against Italian ryegrass, cover crops add to arsenal of control options Many farmers already know cover crops provide a range of benefits. Planted in between cash crop growing seasons when fields would otherwise sit empty, cover crops help reduce erosion, enrich the soil nutrient profile and break up compacted areas.
Now, an LSU AgCenter researcher is exploring another use for these off-season crops: competing with difficult-to-control weeds to keep them at bay.
Donnie Miller, a weed scientist at the AgCenter Northeast Research Station near St. Joseph, has found success in suppressing notoriously unruly Italian ryegrass with a combination of a fall residual herbicide and a planting of cereal rye, a common cover crop. He spoke about his work at a recent field day at the station.
Italian ryegrass has been a growing concern in Louisiana agriculture circles in recent years.
