NOVELTY - Synthesizing organic bio-fertilizer from Camellia sinensis leaves by aquatic extraction method, comprises: collecting or acquiring dried leaves of Camellia sinensis; boiling (101) a preset quantity of the leaves in a preset quantity water, where the quantity of the dried leaves is 6 g, and the dry leaves are boiled at 95 degrees C for 15 minutes; acquiring (102) the Camellia sinensis leaf extract; filtering (103) the leaf extract for removing Camellia sinensis leaves; and adding (104) a sodium sorbate in a pre-set quantity to the extract to obtain a bio-fertilizer.    USE - The method is useful for synthesizing organic bio-fertilizer from Camellia sinensis leaves by aquatic extraction method, where the bio-fertilizer is useful for inducing pest resistance in plants, and the pest is arthropod pest that is a whitefly and a spider mite (all claimed). No biological data given.    ADVANTAGE - The method provides organic bio-fertilizer from Camellia sinensis leaves in an easy and simple manner, where the bio-fertilizer is safe for human health, does not pollute an environment, does not cause damage to host plant or crops, increases a vegetative growth in plants or crops by 2 times, increases a reproductive growth in plants or crops by 1.52 times, improves the resistance of the plants to many arthropod pests, and thus a population density of the whitefly after an application of bio-fertilizer is reduced by 75%, and a population density of the spider mite after an application of bio-fertilizer is reduced by 25% (claimed), functions both as fertilizer and pesticide with no adverse effect of the plants or crops, and induces systematic resistance to destructive greenhouse pests such as spider mites and whiteflies.    DETAILED DESCRIPTION - Synthesizing organic bio-fertilizer from Camellia sinensis leaves by aquatic extraction method, comprises: collecting or acquiring dried leaves of Camellia sinensis; boiling (101) a preset quantity of the dried leaves in a preset quantity water, where the quantity of the dried leaves is 6 g, and the dry leaves are boiled at 95 degrees C for 15 minutes; acquiring (102) the Camellia sinensis leaf extract; filtering (103) the leaf extract for removing Camellia sinensis leaves; and adding (104) a sodium sorbate in a pre-set quantity to the extract to obtain a bio-fertilizer. The pre-set quantity of sodium sorbate added is 0.01-1 g/l, and the bio-fertilizer is applied to plants or crops by many methods (m1). An INDEPENDENT CLAIM is also included for an organic bio-fertilizer composition from Camellia sinensis leaves comprising a Camellia sinensis leaf extract, and a sodium sorbate, where the sodium sorbate is added in a preset quantity to the extract.    DESCRIPTION OF DRAWING(S) - The figure shows a flowchart of synthesizing organic bio-fertilizer.    Boiling a preset quantity of the dried leaves (101)    Acquiring the leaf extract (102)    Filtering the leaf extract (103)    Adding a sodium sorbate (104)
