Utilization of Marigold Extract as Household Insecticide

Most insecticides effective for household use are inorganic which tend to be harmful to the user and to the environment. Recent statistics show that 75% of households use some form of insecticide, with much of this being used indoors. They are used to kill ants and roaches, mosquitoes, flea and tick. By design, these products are all intended to be lethal – to insects that is! People can be affected to some degree as all. Thus, this study aimed to develop an alternative household insecticide utilizing the Extract from Marigold Plant and recycled cigarette butts as highly economic, environmentally safe and user-friendly insecticide preparation with no cost. Marigold Plant is said to contain an active ingredient, phototoxin Alpha-terthienyl which functions as a nematicide.

It is more effective when it is being exposed to sunlight since it generates its phototoxin which makes an interesting natural insecticide. Statement of the Problem: This study aims to investigate the feasibility of Marigold Extract as an alternative household insecticide. Specifically, the study sought to answer the following questions: What are the active chemical components found on Marigold Extract making it ideal as an insecticide alternative? Is there a significant difference on the effect of different Marigold Extract Concentrations on the mortality rate of the insects? Is the use of Marigold Extract feasible as a household insecticide? Significance of the Study The quality of the environment in which people work, live or play, the health of individuals, the quality of certain goods such as food products can all be affected by insects of different kinds.

From time to time, it happens that new kinds of diseases even appear in our environment which are spread around by insects imported from remote areas together with goods. Insecticides can help to address these cases of emergencies. This study aimed to develop an alternative household insecticide utilizing the Extract from Marigold Plant (Tagetes erecta L. ) and recycled cigarette butts as highly economic, environmentally safe and user friendly insecticide preparation with no cost. The result of the study is expected to give information and knowledge to widely addressed the growing demand of ridding these irritating insects out of our sights at the expense of those materials that we could actually found inside our household.

Cigarette butts – are the residue bottom part of a cigarette containing alkaloid nicotine. Extract - obtain something from source: to obtain something from a source, usually by separating it out from other material Insects - are a class of living creatures that have a three-part body three pairs of jointed  and two antennae. Just like mosquitoes, cockroaches, tick, fleas. Insecticides- An insecticide is a pesticide used against insects. They include ovicides and larvicides used against the eggs and larvae of insects respectively. Marigold - is an erect, smooth, branched, rank-smelling herb, o. 3 to 0. 8 meters high. Leaves are 4 to 7 cm long, deeply pinnatifid with linear-lanceolate segments. Marigold (Tagetes erecta L. ) is an erect, smooth, branched, rank-smelling herb, o. 3 to 0. 8 meters high. Leaves are 4 to 7 cm long, deeply pinnatifid with linear-lanceolate segments.

Heads are solitary, 1. 5 to 2 cm in diameter, borne on long peduncles, which are thickened upward. Flowers are pale to deep yellow, sometimes red. Flowers yield a yellow crystalline substance, quercetagetine. The dye was found several shades browner than quercetin. Marigold Plant is said to contain an active ingredient, phototoxin Alpha-terthienyl which functions as a nematicide. It is more effective when it is being exposed to sunlight since it generates its phototoxin which makes an interesting natural insecticide.

Study of roots, leaves and flowers yielded thiophenes, steroidal and terpenoids type constituents. And these secretions coming from the extracted part provides an insecticidal effect on the soil, against nematodes and keeled slugs and insects. While marigolds (Tagetes species) are typically grown for ornamental purposes as bedding plants, studies have found that they can be highly toxic to plant-parasitic nematodes and are capable of suppressing a wide range (up to 14 genera) of nematode pests. Marigold plants produce a number of potentially bioactive compounds, among which ? therthienyl is recognized as one of the most toxic. This sulfur-containing compound is abundant in marigold tissues, including roots.

It has nematicidal, insecticidal, fungicidal, antiviral, and cytotoxic activities, and it is believed to be the main compound responsible for the nematicidal activity of marigold. The control of insect populations is the reason for the use of insecticides. The suffix '-cide' refers to killing. The term may refer to sprays that are chemical, homemade, or organic. The more powerful insecticides have the capability of almost totally eliminating an insect population from a specified area. The less powerful may require several appliations before the desired effects become obvious. Inventions have evolved and continue to evolve such that after several years of study, research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants, we have pursued investigation of the feasibility of Marigold Extract as an ideal component for a household insecticide.
