Retailers and growers continue to face an uphill battle with weed control. Herbicide resistance, reduced herbicide efficacy and loss of chemistries due to regulation are all key factors that require new solutions to maximize herbicide applications to combat post-emergent pests.  

After successful completion of this course, you’ll be able to share with your customers:

  • Effectiveness of herbicides and herbicide activity
  • How the amount and order of ingredients determine the effectiveness of the tank mix
