Organic pesticides are pesticides made from naturally occurring organic mixtures.

Introduction

Organic pesticides can allow farmers to control pest and diseases in plants without resorting to conventional pesticides. This does not necessarily mean that they are safer to use. Organic presticides can be as damaging to the environment as conventional ones. (For further discussion see http://www.bna.com/webwatch/organicpesticide.htm)

This page focuses on providing recipes to help make organic pesticides from locally available materials. This can be of great benefit to farmers in the developing world, where it is often probitively expensive to buy commercial pesticides

Know your problem!

The key to organic pest control using pesticides is to know exactly what the problem in that is causing problems. If pests or fungii can be indentified this can help choose the best pesticide to use.

Here are some resources that can help you identify the problem:
