It is widely available in various parts of Abstract - In recent year the demand of food has been increased by increasing population. Our basic need is to be consume food from plants. But our plants are not safe because, lots of bugs and insects damage and destroy our plant. Solution on this problem is natural pesticide. Due to increases in the industrialization use of synthetic product has been increased. But they give adverse health effect and also damage our environment. Now, in this situation we need to use natural pesticide and they obtain from natural resources like as waste leaves, cow urine, and various extracted oil from leaves and seeds. In this paper we use method of extraction of oil from custard apple seeds. After extraction of oil purify and separation of solvent with the help of distillation. And finally, we manufacture the pesticide using purified oil with the help of emulsifier as Labolene soap.
India, including Andhra Pradesh, Assam, Bihar, Karnataka, Maharashtra, Orissa, Tamil Nadu, and West Bengal. Custard apple seeds are toxic, bitter and can be used as pesticides and fish poison. Cancer treatment involve the use of seed pest. Custard apple seed have confirmed that the major active chemical constituents are annonaceous acetogenins and cyclopeptides. Seed have been shown to have strong antibacterial, anti-ovulatory, anti-inflammatory, anti-thyroidal and other properties. Due to acetogenins group of powerful respiratory inhibiting toxic component which is responsible for oil act as pesticide.
Key Words: Oil Extraction, Distillation, Custard apple seed, Pesticide.

1.INTRODUCTION
Custard apple seed oil contain following acids which shows antioxidant properties as shown in following Table (1)
Pesticide: Pesticide as substances that we are applied to kill undesired organisms. In additional to helping to maintain soil fertility and boost agricultural yield, pesticides are essential for protecting crops from insect assault. In other term “Pesticide” refers to any substance used to prevent, eliminate, repel, attract or diminish pest organisms. Pesticide both natural and synthetic, natural pesticides are those pesticide which we use from ancient time. Peoples who are constantly exposed to pesticide during use they can benefit from using natural pesticides, which are less expensive and more secure. It is created from natural ingredients such as cow urine, waste leaves, seed oil and so on. It benefits soil fertility as well as biodegradable. Synthetic pesticide has become more popular in recent years. As agricultural productivity increases, soil fertility decreases. Bio control is the most effective method for dealing with chemical losses. Oil extracted from custard apple seed using various solvent like hexane, benzene, ethyl acetate etc. Further studies focused for the formulation, modification and determination of some possible properties of oil.
