Gordon's 8081121 2.5 gal HI-DEP Broadleaf Veg Management Herbicide Hi-Dep® Broadleaf Herbicide is a precise combination of the dimethylamine (DMA) and diethanolamine (DEA) salts of 2,4-D formulated to resist crystallization and to hold the droplet size after it leaves the nozzle. This creates a high deposition characteristic that allows more active ingredients to be deposited on the target weed. Hi-Dep moves down to the roots, delivering outstanding post-emergent control of more than 120 tough broadleaf weeds, including Canada thistle, field bindweed, and hemp dogbane.
