Hello plesee please please before spraying any un approved product on any allotment check with the allotment management that it can be used also do a written risk assessment (which I have to do every time I spray ) look for water course no spraying within 5 metres unless you have a PA1a and PA6a aqua spraying licence, a written note needs to be kept of the time the date, wind speed area sprayed ,product ,amount of product ,,try and get a warning sign that says spraying in progress and let people know that spraying is going to take place with in so many days eg spraying here within 21 days that covers you if any one has an allergic reaction to spray products jezza
