Wild Sunflower
CHAPTER I
THE PROBLEM AND ITS BACKGROUND
I. INTRODUCTION Various known plants in the Philippines are considered as weeds. One of which is the Tithonia diversifolia that is commonly known as Wild Sunflower. While it is considered as wild plant, it is also recognized for its significant uses in poultry, agricultural industry and pesticide industry and medicine. The uses and significance of wild sunflower in the Philippines are yet to be introduced and popularized. Wild sunflower, a shrub, can be spotted by the roadside. Aside from the nutritional components that can be obtained from its leaves, reports indicate that the extract from the leaves contains insecticidal properties. One of the most successful of all insects, ants can be a serious nuisance pest in homes, hospitals, restaurants and other buildings. Their ubiquitous nature and social structure make them particularly difficult to control. Small proportions of ants feed on and contaminate our food stuffs that make us consider them as pest on our homes and buildings. The most effective way of inhibiting damages caused by household ants is to ward off these pests using suitable methods.
II. STATEMENT OF THE PROBLEM
The aim of this study is to utilize these plants for the production of insecticide because of their insecticidal properties. Specifically, it aims to answer the following questions:
1. What is/are the insecticidal component/s of the Tithonia diversifolia leaves extract?
2. How does the aqueous extract solution compare to the commercially-available insecticides in terms of the following: 2.1 Physical properties 2.2.1 Color 2.2.2 Odor 2.2.3 Density 2.2 Chemical Properties 2.3.4 pH 2.3.5 Combustibility 2.3.6 Flammability
3. Is there a significant difference between the aqueous extract solution and the commercially-available insecticide in terms of physical and chemical properties?
4. What is/are the effect/s of
