  • Shamsul Mazalan


Synthetic pesticide is commonly used by farmers and in houses to kill pests mainly mealy bugs. Synthetic pesticide functions well but without our knowledge it gives various negative effects to the environment and human health. In conjunction with this, the idea of extracting oil from custard apple seed to produce natural pesticide was executed. The objective of the research is to produce an organic natural pesticide from custard apple seed. Secondly, to determine the amount of methanol solvent used to extract custard apple seed powder. To produce natural pesticide, custard apple seed is required. Moreover, methanol solvent is used to extract the oil from the seed kernels. The extraction is carried out with various amount of methanol solvent along with constant temperature, it is 67℃. The product from the extraction is certain amount of oil and it is classified as natural pesticide. Furthermore, the extracted samples were tested on 9 different plants for 9 days by spraying the pesticide on affected part. The results show the best functioning pesticide is depends on the amount of methanol solvent used. From the research, the objectives have been achieved. The research concludes, the extracted oil from custard apple seed can be used as an organic pesticide.
