e0“PRE mesotrione at rates of 230 or 310 g/ha controlled common ragweed at least 83% in 2002 and 2003, but control exceeded 88% with mixtures of mesotrione at rates greater than 150 g/ha plus S -metolachlor plus atrazine at 560 g/ha.”

Other claims from this paper (10)
- Intervention effect All herbicide treatments caused 11 to 18% corn injury in rainy 2002, with none observed in 2001 or 2003.
- Observation Weed control was generally poor with all herbicides in 2001.
- Intervention effect Mesotrione at 150 g/ha controlled common lambsquarters and smooth pigweed at least 95% in 2002 and 2003.
- Intervention effect Mesotrione at 150 g/ha controlled smooth pigweed at least 95% in 2002 and 2003.
- Intervention effect Control by mesotrione at 150 g/ha was 70% or less in 2001.
- Intervention effect The three-way mixture controlled common ragweed above 88%.
- Intervention effect Mesotrione alone did not consistently control morningglory species.
- Intervention effect The three-way mixture controlled morningglory species at least 90% in 2002 and 2003.
- Intervention effect Corn given any mesotrione rate plus metolachlor and atrazine at 1,120 g/ha consistently had high yield.
- Recommendation The authors recommend at least 230 g/ha mesotrione and 1,120 g/ha atrazine in the three-way mixture for consistent control.
