Banned Herbicides & Pesticides
"Mary Fisher" wrote in message t... A few fag ends infused in water overnight would make a very effective insecticide, but it caused a lot of health and safety problems. But surely this insecticide is pretty organic? :-) Please dismiss the word "organic" from your vocabulary as regards both gardening (and farming) and chemical identity. Technically speaking, any chemical compound that contains at least one carbon atom is "organic". The category embraces everything from carbon dioxide and sugar (both lethal in large enough doses) to virulent poisons of which small doses can kill you in a few seconds. No! Really? Yes, really. To replace "organic" in reference to horticulture goings on, use the phrase "free of petrochemical derivatives not occurring in nature" Oh come on! The sentence to which you are objecting is quite strictly correct. Some usages of words we have to accept according to context. This is a gardening group. Gardeners should realise that they frequently get their knickers in a twist through the misuse of terms which have prior definitions differing from those they *think* are correct. It has, for instance, occurred in this very thread. "Organic" itself is a case in point. There is a great tendency to call "beneficient" chemicals "organic" and others "inorganic". I have just rechecked the definition of the term "organic" in the Penguin Dictionary of Chemistry. ".........Organic chemistry is now the study of the compounds of carbon, whether they be isolated from natural sources or synthesised in the laboratory.........." [Franz Heymann] |
