Botany as a study of plants has identified about 350,000 species of plants which include the Kingdom of Plantae and its organisms of plants. It involves organism such as green algae, herbs, trees, bushes, grasses, vines, ferns.
Viridiplantae known as green plants attain most of the source from the ray of sunlight which is called photosynthesis. Also, organisms include in this group are mainly accepted as descended from a common evolutionary ancestor and not related to other plant-like multicellular organisms such as the Gliricidia sepium (kakawate).
In the Philippines, the extract gained from the leaves of Gliricidia sepium (kakawate) is used to remove external parasites and continuously used for its medicinal and insect repellent properties.Many tropical and subtropical countries used multipurpose legume tree known as Gliricidia sepium (kakawate) like live fencing, fodder, coffee shade, firewood, green manure and rat poison.
Furthermore, a rapid growing waste ground species that take advantage of slash and burn practices in its native range.
Commonly the hated pest in the Philippines is rats which is wild mammals that are considered to be harmful to crops and farm animals, destroy properties also carry diseases such as Leptospirosis, Eosinophilic Meningitis, Murine Typhus and more. Accordingly, on the conflict inflicted by the rats in the remarkable rate, the researchers developed a rodenticide out of Gliricidia sepium (kakawate) tree to solve the rat problem.
