  • Applications

    Dalapon is primarily used as a selective post-emergence herbicide to control grasses in crops and non-crop areas. In practice, its applications include grass control in agricultural crops, turf and lawn management for golf courses and sports fields, maintaining pasture and rangeland by improving forage quality, and vegetation management in areas such as roadsides, industrial sites, and peripheral rights-of-way. Use is subject to local regulations and formulation limits.
