My Lords, I have some sympathy with these amendments. I like the way that the noble Lord, Lord Whitty, has drafted his amendment so that it is not prescriptive, because further work needs to be done.
We are used to buffer strips already: you cannot spray near a watercourse and you cannot put organic manure near bore-holes or wells. Why are human beings excluded from those same provisions? It seems to me a little perverse. I listened with care to my noble friends Lord Naseby and Lord Blencathra; yes, most farmers are good and are careful, but sadly we all know bad farmers. They are the ones causing the damage and are a major cause of the problem that pesticides create.
My noble friend Lord Naseby was right to say that “pesticide” is a generic term. I ask my noble friend the Minister whether she would consider different schemes for fungicides, pesticides and insecticides? Herbicides are probably the least damaging to human beings, but they do leach through the soil, particularly sandy soil, very quickly. The others—for example, insecticides—can be particularly nasty to human beings. It does not require much breeze for there to be quite a fine spray which goes much further than most people recognise. Even in the United States, they are beginning to clamp down on the excessive use of these sprays and have better buffer zones. I think it is time we followed suit; this is something which should be researched and then implemented.
