Putting together some estimates for a couple of potential clients. One client has a day-care center and a section of grass is located inside a fenced in area where the kids play. The request is to treat these areas just like the rest of the property, but I have some trepidations about this because of the following reasons. Toxicity- I don't want the children to play in those areas after treatment. I can time it out accordingly in order to apply on a Fri, or Sat to give the optimal time before re-entry. Phosphate allergies- I know it's rare, but the last thing I want is an adverse reaction from a child that might have this allergy. A phosphorus free fert in those areas might be in order. Now I know that the rule with lawn applications is that there should be no re-entry until the area has dried, but, ag regulations for the same chemicals is no re-entry for one week unless PPEs are used. Any thoughts or opinions on this subject? Thanks.
