Rate 0.008 to 0.031 lb ai/A (0.5 to 2 fl oz/A Aim EC)
Time Apply before, during, or after oats have been planted.
Remarks May be applied as a preplant burndown (up to 1 day before seeding), foliar broadcast or as a harvest-aid. Use a nonionic surfactant (NIS) at 0.25% v/v (2 pints/100 gal spray solution) having at least 80% active ingredient. A high-quality sprayable liquid nitrogen fertilizer may be used at 2% to 4% v/v (2 to 4 gal/100 gal spray solution) or ammonium sulfate (AMS) at 2 to 4 lb/A in addition to the NIS. Tank mixing with other herbicides will increase spectrum of control. Apply to actively growing weeds not more than 4 inches tall, or rosettes 3 inches in diameter. Thorough coverage is essential for good control. To avoid significant crop response, do not apply within 6 to 8 hours of rain or irrigation. Restricted entry interval (REI) is 12 hours
Caution Do not use Aim EC with crop oil concentrates (COC), methylated seed oils (MSO), or silicone-based adjuvants. Do not exceed 0.031 lb ai/A (2 fl oz Aim EC) per crop season. Do not harvest for forage within 7 days after application.
Site of action Group 14: protoporphyrinogen oxidase inhibitor
Chemical family Triazolinone
glyphosate (several trade names)
Rate 0.375 to 0.75 lb ae/A
Time Apply before, during, or after planting oats. Must be applied before oats emerge.
Remarks Prepare seedbeds as far ahead of application as possible to permit maximum weed emergence. Be aware that glyphosate is formulated as 3 lb, 4 lb, 4.17 lb, 4.5 lb, and 5 lb ae/gal; be sure to use the correct amount of herbicide depending on the formulation. Usually, the lowest rate can be used since the weeds are less than 1 inch tall. Glyphosate may be used only as a spot treatment in fields. Do not treat more than 10% of the field to be harvested. Some glyphosate products require adding a nonionic surfactant (NIS); be sure to check the product label. The addition of 1 to 2 percent ammonium sulfate (AMS) by weight or 8.5 to 17 lb/100 gal of spray solution may increase the performance of glyphosate particularly with hard water or spraying during drought conditions. Restricted entry interval (REI) is 4 hours
Caution Carefully check the entire field to ensure that no oats have begun to emerge. Do not let glyphosate drift off target. Do not apply glyphosate through any irrigation system.
