Abstract/Contents:"Mesotrione is an effective broadleaf herbicide, but may not control a broad spectrum of grass weeds. As a result, atrazine and/or acetolactate synthase (ALS) inhibiting herbicides are often mixed with mesotrione for additional grass control. However, recent complaints contend that green foxtail, large crabgrass and shattercane control is reduced when mesotrione is applied in combination with ALS-inhibiting herbicides, especially when the mesotrione rate is reduced. Greenhouse experiments were conducted to evaluate interactions between mesotrione or mesotrione + atrazine and ALS-inhibiting corn herbicides when applied on green foxtail, large crabgrass, shattercane and velvetleaf. Plants were grown in 7-cm containers then treated with 0.25, 0.5, 0.75 or 1 times the use rates of mesotrione (105 g ai/ha), mesotrione + atrazine (105 + 280 g/ha), nicosulfuron (35 g/ha), foramsulfuron (37 g/ha), rimsulfuron (18 g/ha), or a combination of mesotrione or mesotrione + atrazine with any one of the three ALS-inhibiting herbicides. Visual ratings of plant injury were determined 7 and 21 days after treatment (DAT) based on a scale of 0 to 100%. Mesotrione provided greater than 90% control of large crabgrass and velvetleaf, while the addition of atrazine resulted in greater than 98% control of the two species. The addition of an ALS-inhibiting herbicide to mesotrione or mesotrione + atrazine had no adverse effects on the control of large crabgrass or velvet leaf. However, tank mixing mesotrione with nicosulfuron, foramsulfuron, or rimsulfuron resulted in slower green foxtail and shattercane response to the herbicide. Antagonistic interactions were observed 21 DAT on green foxtail and shattercane, when mesotrione was combined with nicosulfuron or foramsulfuron. Similar antagonistic interactions were present when any one of the three ALS-inhibiting herbicides was mixed with mesotrione + atrazine. Results indicate that the addition of an ALS-inhibiting herbicide to a mesotrione application will result in decreased efficacy of ALS-inhibiting herbicides on green foxtail and shattercane."
