***Note: it is not wise or legal to "make your own pesticides." Nor does making your own pesticides make them "organic." The information below should not even be posted. This article is filled with misinformation, and lacks important information through most of it.***
This page focuses on providing recipes of organic pesticides. This can be of great benefit to small-scale farmers as many organic pesticides can be made from locally available materials. It thus allows to circumvent buying expensive chemical pesticides, and also allows them to farm organically and make use of a substance against which resistance will not occur as quickly as with chemical pesticides. ***everything of a material nature IS a chemical. Water is a chemical (H2O), humans are chemicals, everything in the list below (e.g., ethanol, baking soda, etc.) is a chemical. Insects or diseases can become resistant to the CHEMICALS below just as they do to synthetic pesticides.***
