In line with this‚ the researchers decided to research about getting rid of those insects in a natural way. According to the University of Minnesota 2004‚ Chemical Insecticides are a substance that destroys insects by chemical action. Some insecticides also destroy mites‚ ticks‚ and spiders.

Making use of radish extract as an effective alternative method of getting rid of insects and pests like worms‚ ants‚ and aphids was studied in this research project. The purpose of this experiment is to prove that radish extract can be used as an insecticide. The researchers first gathered all the materials needed to complete the experimentation. First washed‚ sliced‚ and pounded the radish tubers using the mortar and pestle. Then the researchers extracted it by using a clean strainer‚ strained
