“The herbicide rate required to provide 95% of weed-free corn yield was 61, 22, 130, and 11% of the MRR for isoxaflutole plus atrazine, dimethenamid plus dicamba/atrazine, glufosinate plus atrazine, and nicosulfuron/rimsulfuron plus dicamba/diflufenzopyr, respectively.”

Other claims from this paper (10)

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 had lowest environmental impact.
Observation Recommended manufacturer rates did not tend to maximize profit margins.
Intervention effect In most cases profit margins did not differ significantly among 40, 60, 80 and 100% MRR treatments.
