Application & Benefits

Overview

• Early post-emergence, one-pass corn herbicide
• Economical and effective weed control
• Contact and season-long residual control of grassy and broadleaf weeds applied at the one- to three-leaf stage of corn
• Three active ingredients with three different modes of action – foramsulfuron (Option Liquid – Group 2), flufenacet (Define – Group 15) and atrazine (Group 5)
• Atrazine is a required tank-mix partner but must be purchased separately

Application Tips

• Mixing order: Define (in slurry), then Option Liquid, then atrazine, then 28% UAN
• For maximum safety, avoid application during > 30 ºC. Spray at least 24 hours before or following near frost conditions (5 °C or less).
• Follow seed company recommendation charts for hybrid sensitivity to sulfonylurea herbicides/ALS inhibitors
• If application is made too early, soil components do all the work controlling the weeds emerging after application and benefits of the foliar components are lost
• If application is made too late, weeds may be too large to be controlled
• Should not be applied on soil with less than 2% organic matter
