A liquid applicator for dispensing a chemical, such as a herbicide, in dilute aqueous form. The applicator has a first container adapted to contain a concentrated chemical and a second container adapted to receive chemical from the first container prediluted with water. A valve controls the flow of chemical and water from the first to the second container and controls the flow of water to an aspirator which further dilutes and discharges the chemical.
