Transcript of Onion (Allium cepa) and Garlic (Allium sativum) As Insect Re

Onion (
Allium cepa
) and Garlic (
Allium sativum
) As Insect Repellent

INTRODUCTION
Plants today—the plants we eat, the plants we use to decorate—have harmful chemicals that we are not aware of. Pesticides contain dangerous chemicals that will harm our body.

The taste and smell of garlic and onion are hated by pests and insects. Mashing/juicing the onion and garlic and getting the extract could drive away the insects away from the plant specimen. It will not only make it easier for the farmers to obtain such substance but it would also save their money. It will be healthier and safer for the eaters of the harvest.

Conclusion and Recommendation
ABSTRACT
The commercial pesticides are mixed with chemicals that may cause harm to our bodies. But with this experiment the risk of the plant and consumer getting harmed is less.

The insect repellent is made of simple materials such as onion (
Alluim cepa
) and garlic (
Allium sativum
). When these two materials are mixed together, the insect repellent is made. The researchers aim to repel the insect not to harm the plant.
SIGNIFICANCE OF THE STUDY
SCOPE AND LIMITATIONS
This project is limited only on the effect of the extract of the onion and garlic as an insect repellent. This is to determine the amount of extract from the onion and the garlic to be used as an insect repellent. We do not expect to kill insects and pests when accomplishing the project. It does not involve the comparison between the extract of the onion and garlic to the commercial one.
BACKGROUND OF THE STUDY
Fruits and vegetables are essential for us all. Also they’re needed in making our
bodies balanced and healthy. We, too, may add them in food to make the dish more beautiful and delicious (e.g tinola, mongos, adobo, apan-apan, etc.). But, what most of us don’t know is that: if they have been applied with pesticides that can be harmful to our bodies.

We have conducted this study so we can see if there is a more efficient and healthier way in protecting the plants from pests/insects. This is not only for the people, but for the farmers and gardeners as well. Having to know more affordable and safer way, is much better than applying pesticides and repellents on plants that can be harmful to people’s health.

This experiment has proven that insects are disgusted by the smell of onion and garlic. From the results, it was seen by the reactions of the grasshoppers that they did not like the stench of the two ingredients.
STATEMENT OF THE PROBLEM
Specifically, the study is aimed to answer the following questions:

1. How should the study be done and developed in order to:
• See that the onion and garlic repellent works and does not harm the plant.

2. What is the level of performance of the experiment based on the following criteria:
• Safe for the plant
• Efficient

This experiment will also help in the budget of farmers and people. Those who are low in budget could easily make this and apply it to their plants. This repellent could help them in their livelihood. It makes their job easier by preventing them for catching the pests themselves.

This is an organic repellent which is better for our health.

Onion, as well as garlic, is good for our bodies and health. With this experiment, we will be healthier than ever. It is also a better consultant than the ones with toxics.

This experiment may take some time to work but it is completely safe and reliable. As a result of this experiment the grasshopper (
Caelifera
) fled from the pine plant (
Pinus
) that was used. The plant was healthy even after a few days (the plant is healthy until now). The three grasshoppers are safe and out of harm’s reach.
All in all, the product worked. The plant was kept safe until the end. No insects were dead. The product was discovered safe. The insect repellent worked and passed the criteria.
Farmers use repellents on their pants to protect them from being eaten by the pests/insects. We do not know if these products they use are good for us.
The researches of this study have conducted this project to help our community—specifically the farmers—to use or create a better way of driving away unwanted pests from their crops. Also, for it to be safer and healthier for the people who eat the harvest. This helps the farmers in a way that they would not have to spend much on the repellents, insecticides and pesticides they normally use.
The researchers are also experimenting whether there is a more efficient and organic way of preventing the insects and pests from nearing the plant.

METHODOLOGY
MATERIALS
• 8 Garlic
• 7 Onion
• One seedling/plant
• Mortar and pestle/juicer
• 5 tbsp of H2O (water)
• Empty sprayer container

• Spray on one seedling and observe that the insects/pests will not near the plant
• Mix with 5 tbsp of water
• Pour the mixture in the empty sprayer
• Crash onion (Allium cepa) and garlic (Allium sativum) in mortal and pestle OR Put them in a juicer
• Pour the extract in a container

PROCEDURE
DEFINITION OF TERMS
Allium cepa- onion
Allium sativum- garlic
Tinola- it is soup wherein you either put horse radish (for fish tinola) or cabbage (for pork/beef tinola)
Mongos- it is another soup dish and its main ingredient are mongo seed
Adobo- a Filipino dish in which you sauté pork/chicken with garlic
Apan-apan- another Filipino dish where the main ingredient is kang-kong

Repellent- it used to repell NOT to kill
Insecticide and Pesticide- used to kill insects and pests
Pinus- pine plant
Caelifera- grasshopper
H2O- water
Pest- "a plant or animal detrimental to humans or human concerns"; alternative meanings include organisms that cause nuisance and epidemic disease associated with high mortality.
Insect- a class of invertebrates within the arthropod phylum that have a chitinous exoskeleton, a three-part body, three pairs of jointed legs, compound eyes and one pair of antennae.

RESULTS AND
FINDINGS
The results of the experiment have been positive. We have tested the mixture on a pine plant (Pinus).The pests we used were green and brown grasshoppers (Caelifera). We placed grasshoppers on the stems and leaves of the plant. After spraying the repellent on the plant the grasshoppers fled to the open fields.
We found out that grasshoppers hate the stench of onion and garlic as much as humans. Due to the stench they had fled. The mixture itself is intoxicating.
This is an efficient and organic way of protecting plants. Although it has a foul smell, it helps the planters with their pest problems.

ANALYSIS OF DATA
We conclude that insects and pests hate the intoxicating smell of garlic and onion. We discovered that the repellent works. It drove away the pests and insects.

Farmers and gardeners should use this for this is easy to obtain and safer. It is completely organic and safe. It is easy to make and you do not have to spend much on it.
It works well. It is sufficient. And it is also easy to use.

This experiment would not be made without the help and support of our parents. This would not have been possible if www.google.com was not made. All the websites that have helped us are factors to this project’s success. To Cang’s Incorporated for selling supplies for this research. The authors and publisher of the “I Wonder Why” books are also part of this.
