The short answer is no.
We do not recommend the use of our products through an irrigation system. Many of our products can stain because of the iron content. Applying products through your irrigation system gives you little to no control over the product getting on landscaping, siding, fences, sidewalks and driveways, all of which can be stained by product. Certain products also have maximum yearly limits, so they need be applied precisely. Instead of using these in an irrigation system, we recommend the use of a hose-end sprayer or backpack sprayer.
