Referring to pesticides: "Organic standards-setting bodies are responsive to new data on toxicity of natural substances and precautionary measured are applied while alternatives are being sought."

"most natural pesticides have a very small persistence in the environment and are, therefore, unlikely to be leave residues in food. Rotenone, for instance, breaks down when exposed to sunlight and has a short lifespan (a week or less) in the environment."

"Research is being undertaken to find alternatives to copper and, meanwhile, organic standards include restrictions on the quantity of copper salt applied to fields."
