The most researched tree, Neem (Azadirachta indicaA. Juss) is found to African countries including Eritrea(locally named as Miim).It has an important in the global context because neem seed, leaves, bark etc. are considered as biological pesticides against insect pests, nematodal infestations and diseases caused by fungi, bacteria and storage pests in the agricultural crops without showing any harmful effects. In Eritrea, the usages of neem products are meager; hence this project projects the introduction of neem oil and cake as ecofriendly pesticide. Seeds of neem collected, de-husked and attained the kernels for the extraction of oil and cakes by cold press extraction method with the help of a devise that was made locally. About 5kg of neem kernels can be used once in this screwed devise which can be streamed 15% of oil and 4.25kg cake within 20-30 minutes. The physical and chemical properties such as specific gravity, viscosity, free fatty acid content, iodine value and saponification values were determined as per the standard procedure to authenticate the pesticidal properties of neem oil. The organic acid contents of neem oil were also analyzed to verify their bioactive properties.
