*WHAM* >>> liquid chitosan ... Agricultural and horticultural use[h=4][
edit] Natural biocontrol and elicitor[/h]In
agriculture, chitosan is used primarily as a natural seed treatment and
plant growth enhancer, and as an ecologically friendly
biopesticide substance that boosts the innate ability of plants to defend themselves against fungal infections.[SUP]
[4][/SUP] 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.[SUP]
[5][/SUP] EPA-approved, biodegradable chitosan products are allowed for use outdoors and indoors on plants and crops grown commercially and by consumers.[SUP]
[6][/SUP] 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.[SUP]

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.[SUP]
[8][/SUP] 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.[SUP]

[10][/SUP] 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).[SUP]
[11][/SUP] Horticultural applications of
chitosan increases blooms and extends the life of cut flowers and Christmas trees
