I just saw an ad for Scotts max weed killer, fert, and crabgrass preventer all in one product. It says to apply when weeds like dandelions are actively growing. Who can tell me what's wrong with this? It's pendimethalin .81%, 2,4 D and 25-2-5- fert. And wait, there's more! It's not supposed to be watered for 2-3 days after applicaton. Problemo numero dos. What kind of moron chemists do they have there? Thank you class!
