Organic farming uses pesticides just as conventional farming does. The only difference is that (with a few exceptions) the pesticides used in organic agriculture have to be derived from “natural” sources. One such example is copper sulfate, which is used in temperate climes as a fungicide. It’s used by both organic farmers although conventional farmers do have synthetic alternatives.

How does this ‘natural’ pesticide compare in toxicity to synthetic or other natural chemicals commonly used by conventional farmers?

Many anti-GMO activists have pointed to pesticides used in conventional agriculture, such as the herbicides glyphosate and the highly toxic organic 2,4-D, as dangerous to people, animals and the environment. For example, anti-GMO organization, The Environmental Working Group, writes this about 2,4-D:............To Read More.....
