Good points thanks Tom. I think starting with home (aka amateur) use of some of the worst pesticides is probably the best first step. E.g. things like systemic plant chemicals that kill any insect that interacts with a plant really has no place in home use, let alone carelessly sold on a shelf in Tescos where anyone could buy it and misuse it. That sort of thing is what I really object to. Treating these things a bit more like a pharmacy does with medicines. Where those qualified to use them (professionals) are the only ones allowed to buy them.
Things like contact organic pesticides and nematodes seem less harmful to a point. Though I do wonder what unknown damage it does to soil ecosystems to pour high concentrations of nematodes into them. No one’s really looked into that. I used to think organic slug pellets were sort of OK in moderation but even those I’m leaning more to being against because they’re generally unnecessary with the correct gardening set up.
It’s hard talking about synthetic vs organic because I think it’s wrong to try and divide everything like that as some chemicals are derived from organic things and some organic chemicals are still chemicals!
Anyway, some more thoughts for us all. I’m not totally set on anything about the systemic pesticides at the moment.
