Surfactants are additives that increase the absorption rate of post-emergent herbicides (weed killers sprayed after the plant emerges from the soil); they allow the active ingredient of the herbicide to penetrate the leaf tissue more effectively allowing for a better weed kill. Surfactants aid in a faster herbicide up take by the weed and more uniform control across the plot area. Most post-emergent herbicides require a surfactant to work properly and will state it on the product’s label. The next time you spray an herbicide on your plot be sure to add Synurgize™ (Nutri-Plot Wildlife Product’s herbicide enhancer) to your tank mix for increased weed control. Synurgize™ is available in 32 oz quarts and requires 6 oz per acre with 10 gallons of water plus herbicide.
