- Threecornered alfalfa hoppers are more problematic in reduced tillage systems. The highest populations are typically observed in late planted fields such as double-cropped soybeans.
- Lodging of plants tends to be worse in fields with low plant populations, and thus, achieving adequate plant stands can reduce the risk of economic injury.
- Maintaining a clean field border may help reduce population numbers.
