ABSTRACT

Synthetic pesticides are known to be dangerous to ones health because of its

hazardous chemical content. To contribute in maintaining the good health of

vegetable plants and preserving their nutrients, the researchers made use of Radish

extract as pesticide. They believe that Radish extract pesticide provides a safe yet

equally profitable effect and poses no threat to the health of the people.

In this study, the effectiveness of Radish tubers extract as pesticide was

tested. The researchers used one kilogram of radish tubers then pounded it with

mortar and pestle. They got the extract with the use of cheese cloth and prepared

four setups. In first set up, radish extract is added with water in a ration of 1:2. In

second set up with 1:1 ratio, in third set up with 2:1 ratio and the fourth set up with

pure extract. All extracts from each set up were used and sprayed in same kind of

pests such as: ants, worms and aphids.

Based on the data gathered it revealed that radish extract can be used as

pesticide and is effective in killing certain pests. It was also found out that pure

radish extract is more effective rather than when water was added to it. It is one

hundred effective in worms and ants and fifty percent effective in aphids.

CHAPTER I

Introduction

A. Background of the Study

Radish is an annual herb widely grown for its edible fleshy, hot tasting roots maybe red,

white or purple. Every part of the root or the plant can be used in different ways. The leaves and

the roots are eaten raw in salads. Likewise, it can be cooked or mix with meat to satisfactory

attain its delicious taste. Aside from food, it is dried for juice extraction.

Radishes were probably native to China. It was developed from a live plant that grows in

the cooler region of Asia. It spread to the Mediterranean region before the Greek era and was

introduced into the new world early in the 16th century. Radishes grow in Asia, Europe and

America. It was the favorite of the ancient Egyptians, Greek and Chinese

There is a little food value in the radish. It is use chiefly as a relish or to decorate salads.

Radishes are the easiest of all garden vegetables to grow, but they should be given in a good rich

soil. The first seed must be sown as soon as the ground is workable and not too cold for the seed

to germinate

B. Statement of the Problem

What is the effect of radish extract as pesticide on certain pests?

C. Significance of the Study

In choosing this project, we wanted to contribute knowledge in maintaining the good health

of vegetable plants by using a pesticide out of radish extract. It maybe helpful in livelihood by

producing good crops. The harvest can be sold to market as an additional income. It can also

minimize the number of planters who used chemical which are found distractive to the

environment.

D. Scope and Limitation

This study focused on the utilization of the extract from radish as pesticide against

different kind of pests like worms, ants and aphids. Experimentation was done in the school

laboratory and at home and was applied in affected green bell pepper plant.

CHAPTER II

Review of Related Literature

Radish, Raphanus sativus, belongs to the cabbage family, rassicaeae. It is grown for its

fleshy root, which varies in sizes from the few grams of popular red American and European

varieties to the one or more kilograms of the Japanese white or draikon.

There are two kinds of radish, one is planted for its crops and the other for its leaves and roots.

Some varieties include Japanese radish, a big and long late harvest radish; and the China radish

which is fine smooth and white. The latter is productive and has a moderate length of time for

harvest. The icicle radish is white, early harvested and its long with small roots. Planters can

harvest the plant in 60 days and other can harvest within 100 days from planting.

CHAPTER III

Methodology

A. Materials:

The researchers need the following materials: mortar and pestle for pounding, empty

bottle sprayer, clean cheese cloth, knife, bowl, water and one kilogram radish tubers. They need

to get pure radish extract, 1:2 proportion of extract to water, 1:1 proportion and 2:1 proportion.

B. Procedure:

First thing to be done is to prepare all the materials needed. Collect one kilogram

of radish tubers and wash them to remove dirt. Slice into small pieces then pound it by

using a mortar and pestle. Put in a clean cheese cloth and squeeze it to get the extract.

Add enough water to the extract in a ration of 1:1, 1:2, 2:1 respectively. Place

each mixture in an empty sprayer and apply it into aphids, worms and ants in plants. Try

several trials to determine the more effective proportion. Record the observation

B. Discussion

It reveals that pure radish extract is more effective rather that when water was added to it. It

is 100% effective in worms and ants, and 50% effective in aphids. This shows that the radish

extract is very effective in killing certain pests.

After several experimentations, we found out that pure 100% radish extract when applied to

aphid, worms, and ants is an effective pesticide. This pesticide can minimize the number of

people who used chemical found and to affect our health and environment.

CHAPTER V

Conclusion and Recommendation

A. Conclusion

Based on the data gathered. We therefore conclude the following:

1. The radish extract can be used as pesticide.

2. Pure radish extract is effective in killing certain pests.

B. Recommendation:

We recommended a more experimentations about radish extract must be done to improve the

quality of the product.

ABSTRACT

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 and acquired the juice of the radish.

After completing the three setups, the researchers sprayed it on the insects and observed what

happened. They tried several trials to determine the more effective proportion and gathered all

the recorded observations.

From the experiment conducted, the researchers observed that pure radish extract is more

effective than the one which was added with water. This shows that the radish extract is

effective in killing certain pests. Therefore, the researchers conclude that the pure radish extract

can be used as pesticide and is more effective than the mixture of the combined water and

extract.

STATEMENT OF THE PROBLEM

This research study helps everyone to know whether the radish extract is really an effective

alternative pesticide; thus, not only helping people to save and apply practicality, but also

reduce the number of people using chemicals as pesticide which are distractive to nature. The

study entitled, Radish Extract as a Pesticide is guided by the following questions:

1. What is the effect of radish extract as pesticide on certain pests?2. Can radish extract be effectively used as a pesticide?[continues]

What chemical substances is in a radish

that can be used as pesticide?In:Chemistry[Edit categories]

Answer:

The only chemical thumbnail of radish I could find in popular scientific references, is this

one:

"The raw flesh has a crisp texture and a pungent, peppery flavor, caused

byglucosinolates and the enzyme myrosinase which combine when chewed to form allyl

isothiocyanates, also present in mustard, horseradish, and wasabi."

Of which the glucosinolates have possible pesticidal properties according to this citation:

"Besides being bitter tasted in cooking, plants producing large amounts

ofglucosinolates are also desirable, because substances derived from these can serve

asnatural pesticides and are under investigation in the prevention of cancer (with

sulforaphane in broccoli being the best known example).
