Why should I use Prime Source Duo Stick surfactant instead of dish soap?

Can't I just use some dish detergent with my herbicide instead of buying this?

Answer:

Many professional herbicides will recommend using a non-ionic surfactant such as Prime Source Duo Stick to increase the efficacy of the herbicide. You will see this primarily on post-emergent herbicides (some herbicides, like many RoundUp products, already contain a surfactant). Besides not being labeled for use as a surfactant or spreader sticker, even a small amount of dish soap would cause foaming in your spray equipment, which would interfere with your spraying and possibly cause the need for extensive cleaning of your equipment. Results from dish soap as a surfactant would be inconsistent, possibly causing you to waste product (and the time you took to apply it) with limited results. Dish detergents may also cause increased phytotoxicity (burning or other damage) to desirable plants, especially during the hot summer months when post-emergent herbicides are often used. Prime Source Duo Stick is a high quality methylated seed oil (MSO) and organisilicone surfactant (OSS) that strips the waxy cuticle of plant leaves for better pesticide absorption while offering excellent spreading and coverage of your herbicide. MSO surfactants are used most frequently with herbicides containing quinclorac, such as Drive XLR8. We sell many other surfactants that can be used with herbicides and pesticides as well. PS 804 Select is a 4-way surfactant that also contains an acidifier and a disposition aid to reduce drift. It also improves penetration of herbicides into the substrate of target plants. We are happy to answer any question you may have about what surfactant may be right for your needs.
