Radish Extract
Chapter I: INTRODUCTION
A. Background of the Study
THE RADISH
The radish (Raphanus sativus) is an edible root vegetable of the Brassicaceae family that was domesticated in Europe in pre-Roman times. They are grown and consumed throughout the world. Radishes have numerous varieties, varying in size, color and duration of required cultivation time. There are some radishes that are grown for their seeds; oilseed radishes are grown, as the name implies, for oil production.
The most commonly eaten portion is the napiform tap root, although the entire plant is edible and the tops can be used as a leaf vegetable.
The bulb of the radish is usually eaten raw, although tougher specimens can be steamed. The raw flesh has a crisp texture and a pungent, peppery flavor, caused by glucosinolates and the enzyme myrosinase which combine when chewed to form allyl isothiocyanates, also present in mustard, horseradish, and wasabi.
Radishes are used in salads, as well as in many European dishes.
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 This study is to determine the ability of Radish (Raphanus sativus) as a pesticide. Specifically it sought to answer the following questions: 1. Can radish extract be used as a pesticide? 2. Can this be as effective as the other commercially available products with the same purpose? 3. Can this be harmless to our health? 4. Can this be cheaper compared to other commercially available products with the same purpose? C. Hypotheses 1. Radish extract pesticide cannot be used as a pesticide. 2. Radish extract pesticide is not as effective as the
