TECHNOLOGY FOCUS - AGRICULTURE - Preferred Process: The step of exposing plant material (fruits, vegetables, leafy vegetables, root vegetables, grains, flower or bulbs) to (I) is carried out by any one of the method: spraying or irrigating (I) in the soil before planting; spraying or irrigating (I) in the soil during plant growth; coating the plant during cutting, dividing or re-planting the plant; coating seed or bulb during planting; coating wilting flowers and shrubs; dispersing on water grown plant; coating plants infected with bacteria or virus; coating cut flowers after harvest; or coating crop and flower after harvest. The plant is repeatedly exposed until all harmful fungi and microbials and related effects are ameliorated. Preferred Composition: (I) further comprises: fertilizer component (ammonium sulfate, urea, potassium, nitrogen and ammonium chloride, chicken manure, cow manure, guano, worm castings, insect manure, saw dust, rice bran, garlic oil, fish oil, vermiculite, montmorillonite, active carbon, charcoal, diatomite, talc, alfalfa meal and pellets, nitrogen, phosphorus, potassium, dried shredded remains of sugar beets, corn gluten, cottonseed meal, extracts or pulverized parts of several kelp or algae, soybean meal, animal processing by-products, blood meal, bonemeal, compost or fish by products); Quercetin; and Rutin (0.1-10), as an additional active ingredient that synergistically works with the Quercetin to inhibit the fungal and microbial growth. (I) comprises Morinda citrifolia n-hexane fraction (.01-10 wt.%).Preferred Components: (I) is comprised of an extract (fruit, stem, seed, pericarp, root bark, leaves and/or root of Morinda citrifolia ), where the extracts are diluted by a factor of 1-10000 times (in weight) with water, before or during application. (I) is made into liquid, granule, powder or paste agent with appropriate carrier materials. (I) is dissolved or dispersed in water. The Morinda citrifolia fraction comprises a Morinda citrifolia Cl2Cl2, ethylacetate and n-butanol fraction. The processed Morinda citrifolia product is processed Morinda citrifolia fruit juice, processed Morinda citrifolia puree juice, processed Morinda citrifolia dietary fiber, processed Morinda citrifolia oil, processed Morinda citrifolia fruit juice concentrate, processed Morinda citrifolia puree juice concentrate, processed Morinda citrifolia leaves, processed Morinda citrifolia roots, processed Morinda citrifolia root bark, processed Morinda citrifolia stems, processed Morinda citrifolia seeds or processed Morinda citrifolia oil extract. ACTIVITY - Plant Antifungal; Antibacterial.    MECHANISM OF ACTION - None given.    EXAMPLE - Typical composition further comprises (wt.%): Morinda citrifolia fruit juice (20-90.8); water (0.1-50); and fertilizer (0.1-30).
