Group 9, Group 15 and Group 27 herbicides
Mode of Action
Halex GT contains three active ingredients, each with a different mode of action.
Mesotrione (Group 27) is a selective herbicide that interferes with the weed’s photosynthetic ability so that it is unable to protect itself from the sun, resulting in bleaching and death.
S-metolachlor (Group 15) is a selective herbicide that restricts root and shoot development, so weeds fail to grow.
Glyphosate (Group 9) is a non-selective herbicide that kills weeds at their growing points.
