(36,927 posts)Not only does your source not prove your assertion, it's completely irrelevant to food production whether it's organic or conventional. The article is referring to home and garden pest control which you could have derived from reading the very first paragraph.
"Organic" is nothing more than a marketing term that doesn't guarantee safety, nutrition, or better environmental impact. Furthermore, copper sulfate is one of the most commonly used organic pesticides. It's highly toxic, carcinogenic, is very slow to break down, and pollutes waterways all over the world, yet it is regulated just as a general use material by the EPA because it's considered "organic" and doesn't require rigorous environmental impact studies like synthetic pesticides do. It's a high use fungicide that's one of the few available to organic farmers who can't use synthetic options that are far more effective, require much less, break down almost immediately, and do not accumulate in the environment like copper sulfate.
