Note: The term ultra low volume (ULV) applies when total spray volume to be applied is 0.5 gal/acre or less and material is applied undiluted. The terms low-volume or concentrate spray apply when total spray volume to be applied will cover the area uniformly but not to the point of runoff. Apply sprays to the point of runoff, usually at a rate of about 0.5 to 1 gal per 1,000 sq ft. The amount of spray needed varies with the surfaces.
