Hi all, I think what we should keep in mind is that all those little chemical helpers are just means to counteract the effects of the unbalance we introduce with our gardening work - we often forget that uncovered open soil is a highly unnatural state, and a lot of those plants we battle are just filling their ecological niche. Personally, I decided against using herbicides in my garden, battling my green nemesis mechanically - sometimes at high costs, killing an Epipactis among other things when eradicating Physalis alkengi, sometimes rather futile with Aegogpdium coming back from surrounding gardens all the time. That way I can at least be sure that I can eat some of that Aegopidium as a minor moment of triumph. And sometimes, I just let volunteers grow to learn what they are - that actually gave me my first Heleborus orientalis. In commercial agriculture I nurture the hope that herbicides will sooner or later be replaced by automated mechanical action - new "intelligent" generations of agricultural equipment can identify wanted and unwanted plants and may even break up the again highly unnatural mono-cultures by selective care without loosing the benefit of automation. As for glyphosate/roundup: I don't care for the hard-to-prove health effects, I already criticize the wanted effects on species diversity. I generally try to stay "chemical free" in the open garden to avoid any unforeseen side effects - with aphids it's a matter of days until the ladybug larvae start fighting back. But I'm definitely not the one to cast the first stone, because of the one thing that gives me red hot rage: my gourmet slugs and their appetite for everything that's unusual, imported and expensive. I couldn't live without slug pellets.
