Pesticide from Radish Extract

Introductions:

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. Objectives

To produce pesticide out of radish extract.


C. Statement of the Problem

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


D. Hypothesis

There is no significant difference in using this natural pesticide from radish extract.


E. Importance 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.

F. 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 our backyard and was applied in affected Guyabano plants and sugar apple fruit.


G. 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.


METHODOLOGY


Materials:

Mortar and Pestle
Empty Bottle sprayer
Clean cloth / katas
Knife
Bowl
1 kg Radish tubers
1 L pure radish extract
250 ml of 1:2 proportions, extract to water
250 ml of 1:1 proportion
250 ml of 2:1 proportion

Procedure:

1. Prepare all the materials needed
2. Collect one kg. of radish tubers
3. Wash them to remove dirt
4. Slice into small pieces
5. Pound it by using a mortar and pestle
6. Put in a clean cloth. Get the extract
7. Add enough amount of water to the extract in a ration of 1:1, 1:2; and 2:1 respectively.
8. Place each mixture in a sprayer bottle and applied into aphid, ant, worm affected sugar apple and guyabano plants.
9. Try several trials to determine the more effective proportion.
10. Record your observation.



RESULT AND DISCUSSION

Observation on the insecticidal effect of radish extract in certain pests

Trial Proportion Volume Length of Number of Insects
Extraction ML Application Worms Ants Aphids
Mean

1 pure 250 10 10 10 all found in
one fruit
2 2:1 250 10 10 10 all found in
one fruit 10
3 1:1 250 10 10 10 all found in
one fruit 10
4 1:2 250 10 10 10 all found in
one fruit 10

Insecticidal effect of radish extract

Trial Number of Insects Killed Percentage

1 10 10 half 100 100 50

2 1 2 none 10 20 0

3 0 0 none 0 0 0

4 0 0 none 0 0 0



Explanation

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.



Findings:

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.


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.


Recommendation:

We recommended a more experimentations about radish extract must be done to improve the quality of the product.

what chemical component in radish makes it possible to be used as pesticide?

MarveLouise said...

where's the comment sheet? plus, what is combined in the radish to make it more effective in killing this certain pest? Add the table or your appendix 1 on the Plan for Analysis. Is this approved by your teacher?
