Chitin and Chitosan is obtained from natural and have vital role in agriculture and diverse field. They generally called as a “Defense Booster” involves boosting defense mechanism of plants against invading microorganisms. Chitin and Chitosan are potentially used as a plant growth enhancer to boost up the host defense to defeat against fungal infection and pathogens.Read more
The defense response is increased to conquer microbial infection, includes accumulation of Pathogen related proteins , phytolaxiens and proteinase inhibitors, lignin synthesis, and callose formation. Chitosan is widely applied in the range of fruits, Chitosan Plant Protection and vegetables likes Capsicum, Carrot, Cucumber, Grapes Green peas, Potato, Radish Tomatoes for increased host defense. Chitosan mediated seed treatment serves improved seed quality and enhanced energy of germination, germination percentage, lipase activity, and gibberellic acid (GA3) and indole acetic acid (IAA) levels, i.e. in peanut. These treasures can be used in many ways to preserves and increase the crop yield and to improve the quality of fruits and vegetables.
Food safety is become critical issues because the agricultural product such as fruits and vegetables should be preserved in good condition before consumed by peoples. The infection of fungi on storage could decrease the quality and safety. The post harvest decays from injuries during post harvest and by handling and transportation leads to wounds. Through the wounds the fungi spores get deposited and cause fruits decay. Controllig the pre and post harvest diseases is become more complex. Continuous use of excessive amount of fungicides leads to resistance level of fungi and to negative impact on human health. Instant use of chitosan – Defense Booster gives resistance to gas such as O2, CO2 and in respiration level. Poly D- glucosamine binds to fungi receptors and by mimick the attack by spores and gives signal to plant which bring out various genetic and biological responses. The level of inhibition of fungi is depends on the concentration of chitosan. The enhanced antifungal activity of chitosan is owing to its polycationic nature and polymer chain length. Chitosan is recommended to be used as biopesticide for post harvest plants.
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.
