Chitosan is a substance made of chitin shells from crustaceans like schrimps. It has a number of commercial and biomedical uses. It's mostly used in agriculture as a seed treatment to boost the plant resistance and to increase the yield.
Chitosan represent a new tier of cost effective biological control of crops for agriculture and horticulture. It activates the
innate defence responses within the plants to resist insects, pathogens and soil-borne diseases when applied to the soil. It also
increases photosynthesis, promotes and enhances plant growth, stimulates nutrient uptake, increases sprouting, boosts plant vigor and increases starch levels. The applications of chitosan can reduce environmental stress due to drought and soil deficiencies, strenghtening seed vitality and stand quality and reduce decay of vegetables, fruits and citrus crops. Not only is it very effective to use, it also has a low potential for toxicity and abundance in the natural environment. It does not harm people, pets, wildlife or the environment when used according to label directions.
Chitosan also has plenty of other uses outside of agriculture:
It can be used in hydrology as a part of a filtration process, through its ability to remove heavy minerals, dyes and oils from the water.
It has a long history for use as a fining agent in winemaking.
Itís properties to rapidly clot blood gives it a lot of biomedical uses.
Itís used as a food coating and enhancer.
Itís also present in creams, lotions, underwear, paper, soda and textile.
