ProShield 5L is a dual-active total weedkiller formulated for professional use to provide both immediate knockdown and long-lasting residual control of a broad spectrum of annual and perennial weeds. Combining glyphosate (250g/L) and diflufenican (40g/L), ProShield is the ideal solution for hard surfaces, industrial zones, fence lines, and amenity areas, offering up to 4 months of residual control from a single application.

ProShield can be applied via knapsack sprayer or boom sprayer, making it versatile for large and small-scale weed control projects.
