Two major websites that cover the issue of safety with chemicals and pesticides are:
The Pesticides Safety Directorate official website – a UK Government backed website with lots of guidelines on the subject.
http://www.chem-tox.com/ - a US site with lots of detailed information. “Poison In The Grass” is the heading of one of their alarming reports which covers the hazards and consequences of lawn pesticides (http://www.chem-tox.com/pesticides/pesticidereport.htm).
Whether you believe the reports or not, you must ask yourself:
Do you have time to study all this information, then go into the local garden centre to delve through all the options of what’s available only to then have to commit to trying something out, not knowing the outcome?
Sounds like an awful waste of time and energy particularly when the real lifestyle choice of artificial grass offers a simple and effective solution.
