So the bottom of my SG-120 sprayer hose connection under pressure spun off (vibration or not checked) and spray weed killer down my back. Before I realized what happened I ran off the lawn, but I have these hideous burn spots.I was doing weed control in the mulch rings and beds. I tried fertilizing and throwing new seed down, but the days range from 50-70* and nights have been 37-25* . I really need to fix this spot and do not know where to go about doing this as it has been a month an still the eye sore. My client has been patient too. Thank you so much for any help.
