- Intervention effect Redvine control declined with shallow tillage and non-GR cultivars.
- Observation The decline in redvine control did not cause a yield decline.
- Intervention effect Johnsongrass control averaged below 40% with non-GR cultivars.
- Intervention effect Johnsongrass control averaged above 93% with GR cultivars.
- Association The johnsongrass control difference was associated with lower yield.
- Association Fall tillage by weed-management interaction was not significant for yield.
- Association Fall tillage by weed-management interaction was not significant for net return.
- Recommendation The authors conclude deep tillage for perennial weed management is uneconomical.
