Assessing weediness potential of Brassica carinata (A.) Braun in the southeastern United States

Carinata (Brassica carinata (A.) Braun) is a promising winter oilseed crop in the southeastern US, and ensuring agricultural and ecological safety is critical for growers. The present study evaluated the weediness and invasiveness potential for carinata in the southeastern US. A field study was conducted in Goldsboro and Clayton, North Carolina comparing emergence and survival of volunteer carinata with and without predator exclusion. Cumulative seedling emergence at both locations was highest for buried seeds with predator exclusion (42% and 15%) and lowest in unburied seeds without predator exclusion (16% and 1%). Survival 90 days after planting (DAP) at both locations was highest for buried seeds with predator exclusion (10% and 5%) and lowest in unburied seeds without predator exclusion (3% and
