- Intervention effect For isoxaflutole plus atrazine, rates providing 95% biomass reduction were respectively 92, 30, 41, 28 and 83% MRR for velvetleaf, redroot pigweed, common ragweed, common lambsquarters and annual grasses.
- Intervention effect For dimethenamid plus dicamba/atrazine, corresponding 95% weed biomass reduction rates were >200, 119, 23, 23 and 117% MRR.
- Intervention effect For glufosinate plus atrazine, corresponding 95% weed biomass reduction rates were 141, 72, 46, 45 and >200% MRR.
- Intervention effect For nicosulfuron/rimsulfuron plus dicamba/diflufenzopyr, corresponding 95% weed biomass reduction rates were 81, 29, 18, 24 and 88% MRR.
- Intervention effect Isoxaflutole plus atrazine required 61% MRR for 95% weed-free corn yield.
- Intervention effect Dimethenamid plus dicamba/atrazine required 22% MRR for 95% weed-free corn yield.
- Intervention effect Glufosinate plus atrazine required 130% MRR for 95% weed-free corn yield.
- Intervention effect Nicosulfuron/rimsulfuron plus dicamba/diflufenzopyr required 11% MRR for 95% weed-free corn yield.
- Intervention effect Nicosulfuron/rimsulfuron plus dicamba/diflufenzopyr had lowest environmental impact.
- Intervention effect In most cases profit margins did not differ significantly among 40, 60, 80 and 100% MRR treatments.
