The natural biocontrol active ingredients, chitin/chitosan, are found in the shells of crustaceans, such as lobsters, crabs, and shrimp, and many other organisms, including insects and fungi. It is one of the most abundant biodegradable materials in the world. Degraded molecules of chitin/chitosan exist in soil and water. Chitosan applications for plants and crops are regulated by the EPA, and the USDA National Organic Program regulates its use on organic certified farms and crops.EPA-approved, biodegradable chitosan products are allowed for use outdoors and indoors on plants and crops grown commercially and by consumers.The natural biocontrol ability of chitosan should not be confused with the effects of fertilizers or pesticides upon plants or the environment. Chitosan active biopesticides represent a new tier of cost-effective biological control of crops for agriculture and horticulture.The biocontrol mode of action of chitosan elicits natural innate defense responses within plant to resist insects, pathogens, and soil-borne diseases when applied to foliage or the soil. Chitosan increases photosynthesis, promotes and enhances plant growth, stimulates nutrient uptake, increases germination and sprouting, and boosts plant vigor. When used as seed treatment or seed coating on cotton, corn, seed potatoes, soybeans, sugar beets, tomatoes, wheat and many other seeds, it elicits an innate immunity response in developing roots which destroys parasitic cyst nematodes without harming beneficial nematodes and organisms. Agricultural applications of chitosan can reduce environmental stress due to drought and soil deficiencies, strengthen seed vitality, improve stand quality, increase yields, and reduce fruit decay of vegetables, fruits and citrus crops (see photo right).Horticultural applications of chitosan increases blooms and extends the life of cut flowers and Christmas trees. The US Forest Service has conducted research on chitosan to control pathogens in pine trees. and chitosan's ability to increase pine tree resin pitch outflow by 40% to resist pine beetle infestation.</span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px"> </span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px">Water filtration</span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px"> </span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px">Chitosan can also be used in water processing engineering as a part of a filtration process. Chitosan causes the fine sediment particles to bind together, and is subsequently removed with the sediment during sand filtration. It also removes phosphorus, heavy minerals, and oils from the water. Chitosan is an important additive in the filtration process. Sand filtration apparently can remove up to 50% of the turbidity alone, while the chitosan with sand filtration removes up to 99% turbidity.Chitosan has been used to precipitate caseins from bovine milk and cheese making.<br /> </span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px"> </span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px">Potential industrial use</span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px"> </span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px">Scientists have recently developed a polyurethane coating that heals its own scratches when exposed to sunlight, offering the promise of scratch-free cars and other products. The self-healing coating uses chitosan incorporated into traditional polymer materials, such as those used in coatings on cars, to protect paint. When a scratch damages the chemical structure, the chitosan responds to ultraviolet light by forming chemical chains that begin bonding with other materials in the substance, eventually smoothing the scratch. The process can take less than an hour.<br /> </span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px">Biomedical uses</span></p> <p> <span style="font-family: ?arial?black, avant?garde; ?font-size: ?12px"> </span></p> <p> </p>
