I am involved in a project to collect obsolete and unwanted
pesticides and pesticide containers.
To get an idea of what is out there, a survey has been proposed as a
possible initial step.
It would be enormously helpful if anyone with experience in this area
could provide me with any advice. Suitable survey questions, potential
pitfalls, overcoming farmers suspicions, the best approches to take to
organising the collection would all be useful information.
