Better Liquid Solution Application: PetraTools Sprayer’s Surfactant for Herbicides is formulated to allow solutions to penetrate the plants more effectively. It works by breaking down waxy surfaces for better liquid application. It’s ideal for use with weed killers and other herbicides, insecticides, fungicides, fertilizers, and many more.
Works Best with PetraTools Sprayers: Applying herbicides and other liquid plant treatments can be quick and more effective when used with a durable and quality-tested sprayer. That’s why we recommend using the surfactant with our Battery Sling Sprayer, HD4000, HD3000, HD5000, LT-PRO, or HD4050.
Improved Nutrient Absorption: Our surfactant contains ammonium sulfate that helps plants absorb nutrients better. You’ll see healthier growers with less fertilizer. Compatible with tenacity herbicide, speedzone, spectracide, drive xlr8, sedge hammer, milestone and all herbicides.
Easy Identification of Liquid Applications: PetraTools Sprayer’s Blue is a highly concentrated water soluble spray colorant for fertilizers, herbicides, and weed killer products. With its extremely visible blue color, you can quickly locate the liquid products applied on your lawn and clogged nozzles or blockages in your sprayer. Saves you time spraying!
Quickly Fades: No need to worry about seeing your yard blue for a long time! Our blue turf mark will fade in 24-48 hours. It naturally disappears with rainfall and exposure to sunlight and doesn’t stain your shoes, clothes, or pets.
