Roundup Pro Herbicide is a post emergent herbicide concentrate for industrial, turf, ornamental, forestry, roadside, utility rights-of-way, railroad management and other listed terrestrial weed control areas. Roundup Pro Herbicide provides broad-spectrum control of many annual and perennial weeds, woody brush, trees and vines. It is a water-soluble formula to be used by mixing with water or other carriers according to label directions. This product binds tightly to soil particles and does not provide residual weed control. Weeds must be emerged at the time of application to be controlled by foliar application of product. For enhanced results, spray coverage must be uniform and complete. Foliage should not be sprayed to the point of runoff. Rainfall within 4 hours of application could wash this product off of the foliage and a second application may be needed for acceptable weed control. Roundup Pro Herbicide Weed killer may be applied with several different types of application equipment (refer to label).
