I have several questions. 1. What are the chemical ingredients of this fertilizer? Is it dangerous to humans, like a pesticide? And do any of its constituents bioaccumulate in the human body and contribute to the overral chemical body burden, exacerbating chances of cancer, illness, dementia, etc? 2. How long does the chemical fertilizer stay active, after being sprayed? Ergo, what is the appropriate re-entry time? My dog walked through a yard that had been sprayed with it, about seven hours after treatment. Could the dog then track these chemicals back into my home, where they can get into my body and hurt me? 3. Does this stuff essentially absorb into the grass and make it toxic? If the next day, someone cut the grass, does this make the "fresh cut grass smell" poisonous and neurotoxic, when inhaled? (The day right after it was sprayed on, the lawn was cut. Could the smell presently engulfing the house be toxic? 4. Does this chemical soup spray contain any 2,4-Dichlorophenoxyacetic acid, or some other chemical constituent which does or might contain dioxins? 5. Are the chemicals capable of permeating through brick walls and glass? They were sprayed in front of my room. Can any of it faze through inside where I'm at, for me to inhale?
