To control the negative effects of synthetic pesticides, natural organic pesticides should take place to be an alternative to synthetic pesticides which have a lot of harms on the environment and public health. These alternatives are natural materials work as killers or repellents to reduce, destroy and kill pests which affect human health and environment. In this research, the effectiveness of natural organic pesticides has been tested by doing preliminary experiments as a first methodology composed of 11 ingredients of natural materials with different concentrations to choose the most effective components and mix them in one treatment (pesticide). The results were very positive for some of them and showed how these organic pesticides are effective in term of killing and repelling pests. Neem oil, Lavender oil, and Cottonseed oil were the most effective with high degradation time. On the other hand, Chrysanthemum liquid was the least effective as it is a liquid, not oil (oil is more concentrated). Moreover, Garlic oil and Mint oil were effective as repellants with high degradation time. For the second methodology where the most five effective materials based on the preliminary experiments have been mixed together to form one pesticide. The final pesticide showed effective results on stick insect and ants. Lack of studies about natural organic pesticides was an obstacle in this research, where some ingredients have not been scientifically tested in previous studies. This research could help to change from chemical activities used in agriculture field to more friendly methods in term of sustainable agriculture.
