Optill ® herbicide tank-mixed with glyphosate, provides rapid burndown plus early season residual control for cleaner fields in glyphosate-tolerant soybeans.

  • Powered by Kixor ® , for a fast, complete burndown.
  • Residual activity keeps fields weed-free during early crop development.
  • Multiple modes of action, to help prevent and manage resistant weeds.

How it works

  • The better weed control of Optill plus glyphosate has been shown to increase soybean yield by 2 to 3 bushels per acre, compared to using glyphosate alone.
  • Optill uses Group 14 and Group 2 active ingredients that complement glyphosate to provide a faster, more complete burndown than glyphosate alone.
  • The residual power in Optill is effective into early crop development allowing increased time and flexibility to apply a second, in-crop application of glyphosate.

When to apply

Crop Timing
Soybeans pre-plant surface application

How much to apply

One case will treat 120 acres. Optill is tank mixed with glyphosate for application at the following rates:

Timing Application Rates
Early Pre-plant Optill herbicide + glyphosate* 60 g/ac (147 g/ha)
Water volume 40-80 L/ac (100-200 L/ha)
Merge adjuvant** 0.40 L/ac (1 L/ha)

* See glyphosate label for application rates.
**Addition of Merge adjuvant (not included) is required for optimum activity.

Application tips

  • Flat fan or similar spray nozzles should be used for application
  • Water Volume should be between 40-80 L/ac (100 to 200 L/ha)
  • Denser weed infestation requires the use of higher water volumes
  • Recommended pressure is 275 kPa
  • Rainfastness – 3 hours after application
  • Residual pre-plant applications of Optill must be activated by at least ½ inch of rainfall or sprinkler irrigation prior to weed seedling emergence

Follow crops

Following an application of Optill, the crops listed can be planted in the season indicated.

Same Season (in case of crop failure 1 ) Soybeans, Winter wheat 2
