This invention was not federally funded.
BACKGROUND OF THE INVENTION
The present invention relates generally to pest repellant compounds. More particularly, the invention relates to a compound for repelling sucking insects such as white flies, mites and other types of destructive insects. The compound is especially effective in protecting poinsettia and gardenia plants.
White flies are small snow-white insects that resemble moths. When viewed with the naked eye, white flies typically resemble flying dandruff. They are destructive insects that feed by sucking plant juices, thus depleting the plants of vital nutrients. Leaves of plants that are infested with white flies may have spots or blotches of different colors or shades. If left alone, the leaves of an infested plant will yellow and the plant will eventually die.
A harmful secondary effect created by white flies is a honeydew type material that is excreted by these insects. This sticky material glazes the leaf surface, thereby permitting the development of black mold fungus. The black mold fungus interferes with photosynthesis and retards plant growth.
White flies have many species and attack a wide variety of plants. Examples of plants attacked by white flies include bedding plants, cotton, strawberries, vegetables, and poinsettias.
Traditional methods of treating infestations of white flies include applying potent pesticides to infected plants for extended periods of time. Applications of pesticides on infected plants enjoy limited success. Since white flies have two life stages, they are tolerant to most insecticides. In order to properly treat plants that are infested with white flies, the pesticides must be sprayed onto the under surfaces of the leaves of the infected plants.
Another method of controlling the populations of white flies is the use of predatory insects that consume white flies. This method is somewhat successful in greenhouse or closed environments. In open-air environments, the predatory insects may be consumed by birds and other predators that are higher on the food chain. Also, predatory insects may migrate from the plants to be protected when used in open-air environments.
Another technique for controlling white fly populations requires the use of a vacuum infiltration with soap solutions. This method causes the white flies to explode. In this method, an infected plant is placed in a soap solution. The plant is then put into a vacuum chamber and a vacuum is drawn. Since the white fly's body is comprised mostly of gas, the gas is drawn out when the vacuum is drawn. When the vacuum is released, the soap solution is drawn into the fly's body. The fly expands until it ruptures. While this method is effective in reducing the population of white flies, it is time intensive and requires special equipment.
While the aforementioned techniques have demonstrated limited success in treating infestations of white flies, these techniques are rarely a total solution for treating plants with infestations. Moreover, the techniques are not cost effective. The present invention intends to teach a superior method of treating plants that are infested with white flies.
BRIEF SUMMARY OF THE INVENTION
The present invention provides a pest repellant composition that is effective for controlling harmful pests, specifically white flies. It also teaches a cost-effective process for manufacturing the composition by using recycled by-products.
The present composition includes a mixture of water (H
2
O), calcium carbonate (CaCO
3
) and hydrogen sulfide (H
2
S). The preferred mixture of the composition is 250 ml H
2
O, 24.3 g CaCO
3
and 0.424 mg/I H
2
S. To properly treat plants, the mixture should be present in an amount of ½ milligram per liter of water. The composition may also include food coloring or propylene (C
3
H
6
). The preferred food colors are FD&C #1 blue, #5 yellow or #6 yellow. Typically, the composition includes one drop of #1 blue and 0.5 drop of #5 or #6 yellow.
The present invention also contemplates a cost effective method of producing the above composition. The process includes adding eggshells with a portion of the albumen to hot or warm water and allowing this mixture to cure or ferment for several days. In the preferred embodiment, the mixture is allowed to cure for at least twelve days. The amount of time necessary to appropriately cure the mixture may vary according to different temperatures and various environmental conditions. Concentrated amounts of the present composition may be produced by adding additional quantities of albumen to the composition. The concentrated composition may be later added to water to produce large amounts of the composition.
It is an object of the invention to provide a cost effective way of dealing with infestations of white flies.
It is also an object of the invention to provide an environmentally safe method of treating plants to repel harmful insects such as white flies.
It is a further object of the invention to provide a pest repellant that is safe to human and animals.
It is another object of the invention to provide a repellant that provides nutritional value to the treated plant.
It is another object of the invention to provide a cost effective and easy method for producing the compound.
It is still another object of the invention to use recyclable waste by-products to produce the compound.
These objects and others will become apparent when the aforementioned discussion is taken in conjunction with the following disclosure.
DETAILED DESCRIPTION OF THE INVENTION
The following is the preferred embodiment or best mode for carrying out the invention. It should be noted that this invention is not limited by the discussion of the preferred embodiment.
There are many parts of an egg including the albumen or egg white. Typically, the albumen accounts for about sixty-seven percent of an egg's weight. The albumen contains more than half of the egg's total protein, minerals and vitamins. The albumen contains protein, niacin, riboflavin, chlorine, magnesium, potassium, sodium and sulfur.
The pest repellant is produced by fermenting eggshells with a portion of the albumen attached thereto. Fermentation is the chemical process that breaks down organic materials. The process is carried out by bacteria, molds and yeasts that are present in the air. It is believed that the fermentation process liberates sulfur from sulfates and sulfides present in the amino acids of the eggshells and albumen.
A chemical analysis of chicken eggs was undertaken and the following results were yielded. One-hundred grams of fresh chicken eggs contains approximately 70.83 g of water, 12.14 g of protein and 11.15 g of lipids. Minerals present in the eggs were as follows: 56 mg of C, 2.09 mg of Fe, 12 mg of Mg, 180 mg of P, 130 mg of K, 138 mg of Na and 1.44 mg of Zn. Vitamins included in the fresh eggs were as follows 0.087 mg of Thiamin, 0.301 mg of Riboflavin, 0.062 mg of Niacin, 0.120 mg of B6, 1.547 mg of B12 and 520 IU of A. The chicken eggs also included amino acids in the approximate quantities: 0.820 g of Lysine, 0.392 g of Methionine, 0.289 g of Cystine, 0.596 g of Threonine, 0.759 g of Isoleucine and 0.686 g of Phenylalanine.
Methionine and Cystine both include sulfur. Methionine is represented by the following structural formula.
Cystine is represented by the following structural formula.
Since the eggshells and albumen contain amino acids that comprise sulfur, sulfur dioxide is created during the fermentation process. Sulfur dioxide is a colorless gas with a distinctive odor. The sulfur dioxide contributes to repelling the pests as it is placed on the leaf surfaces of the plant. The plants also absorb the sulfur present in the mixture of eggshells and albumen and give off a sulfur smell that repels pests.
Another important element in the pest repellent is sulfide. Sulfide is a chemical compound that contains sulfur and another element. All sulfides contain the sulfide ion, a single sulfur atom with a
