Breakfree® ATZ Herbicide

Provides Excellent Cost-effective Preemergence Control of Annual Grasses

A proven performer, DuPont™ Breakfree® ATZ herbicide provides excellent cost-effective preemergence control of annual grasses in corn, including barnyardgrass, crabgrass and foxtails. It also delivers control of small-seeded broadleaf weeds for added value.

Breakfree® ATZ has a user-friendly formulation that allows application flexibility from early preplant to early postemergence. It fits conventional, reduced-till and no-till corn production systems and can be tank mixed with other labeled preemergence herbicides for broader-spectrum control and to help reduce trips through the field.

Breakfree® ATZ delivers efficient time management because it can be applied in water, liquid or dry fertilizer.

DuPont™ Breakfree® ATZ herbicide along with DuPont customer service and DuPont-sponsored programs delivers on the promise to go beyond crop protection to make every acre count from seed to harvest.

DuPont™ Breakfree® ATZ is a restricted-use pesticide.
