Chapter II: Review of Literature and Conceptual Framework

Review of Literature:

Garlic is commonly used in culinary and medicine. It grows up to 0.5 m (2ft) in height. Garlic helps prevent heart disease including atherosclerosis, high cholesterol, and high blood pressure and cancer. Garlic is used to prevent certain types of cancer, including stomach and colon cancers. A Czech study found garlic supplementation reduced accumulation of cholesterol on the vascular walls of animals and garlic also cause insects to react due to its allicin. Allicin is an antibiotic substance that is found when the garlic is crushed. The composition of bulbs is approximately 84.09% water, 13.38% organic matter, and 1.53% inorganic matter, while the leaves are 87.14% water, 11.27% organic matter, and 1.59% inorganic matter. Allicin is an antifungal compound (phytoncide) discovered by Chester J. Cavallito and colleagues in 1944. It has been claimed that allicin from crushed garlic can be used as a home remedy to help speed recovery from strep throat or other minor ailments because of its antibiotic properties. By this, we found out that garlic might be effective because of the compound it contains to kill insects in a certain affected plant. It is believed by some to act as a mosquito repellent, but no clinically reported evidence suggests it is actually effective. So we are going to test this garlic insecticide to prove this study. The center point of this study is to create an organic pesticide, a pesticide is a substance formed and established by scientists to act as repellent to harmful insects or organisms that benefit on a certain body that is infected or harmed. It is produced to dissolve the capability of harmful organisms to infect or continue to harm an organism. None of these discoveries and studies involved garlic as pesticide. We are going to prove this study.

Conceptual Framework:

Garlic as Insecticide
Hypothesis:
The garlic pesticide...
