Product Information

Helmet Maxx is a pre-emergence and post-emergence herbicide for use in corn (field corn, field corn seed, and field corn silage). This product may also be applied to sweet corn, yellow popcorn and grain sorghum as pre-emergence applications prior to crop emergence, or severe adverse crop response may result.

This product will not provide consistent control of grasses that have emerged at the time of application. HELMET MAXX is a mixture of three herbicides, metolachlor, mesotrione, and atrazine with a safener added. It works to control weeds by interfering with the plant’s ability to germinate and develop.
