Glyphosate-tolerant corn solutions

The Callisto Plant Technology® herbicide portfolio provides a range of products that are safe to the crop and perform well to meet the needs of today’s corn growers.

Callisto Xtra

  • Where glyphosate is less effective on tough broadleaf weeds, using Callisto Xtra® herbicide as a tank-mix partner delivers added control while providing an extra mode of action to combat weed resistance.

Lumax EZ & Lexar EZ

  • Lumax® EZ herbicide and Lexar® EZ herbicide are the best opportunity for one-pass weed control in corn, but for growers planning a two-pass program, Lumax EZ and Lexar EZ widen the window of application for a post-emergence application of a Touchdown® brand herbicide or Halex® GT herbicide if needed.


  • Zemax® corn herbicide delivers long-lasting residual weed control and application flexibility in areas where atrazine use is limited. Through its combination of two active ingredients – Callisto® and Dual Magnum® herbicides– Zemax provides residual control of the toughest grasses and small-seeded broadleaf weeds.

Halex GT

  • Halex GT herbicide is Glyphosate with Residual and offers the best opportunity for one-pass, post-emergence broadleaf weed and grass control with a single product in glyphosate-tolerant corn.
  • For growers planning a two-pass program, Halex GT is the post-emergence partner of choice following an application of a Bicep® brand herbicide, Dual® brand herbicide, Princep® brand herbicide, Lumax EZ herbicide or Lexar EZ herbicide.
  • If time gets away from you, or Mother Nature throws you a curve ball, Halex GT herbicide tank mixed with atrazine (AAtrex® 4L or AAtrex Nine-O® herbicides) is the best choice for one-pass post-emergence weed control in glyphosate-tolerant corn.

A two-pass program of Lexar EZ, Lumax EZ or Zemax followed by Halex GT tank mixed with atrazine (AAtrex 4L or AAtrex Nine-O) or Touchdown Total tank mixed with Callisto Xtra controls yield-robbing early-season weeds, provides long-lasting residual to manage them all season long and delivers multiple modes of action for pre and post control offering the most sustainable option for weed resistance management. This leads to optimum yield and maximum return on investment.
