“…The row material of chitosan ( Figure 1) is chitin ( Figure 2) which is a biodegradable polymer produced from crab or shrimp shells [7][8][9]. Recently, chitin or chitosan produced from mycelia of Zygomycetes fungi as alternative sources (Krishnaveni and Ragunathan, 2015 and Khalil, 2016) [9]. The treatment of crustacean shells with alkali solution (NaOH) is mainly remove proteins and this process called Deproteinization, while to remove CaCO 3 (Demineralization) from crustacean shells it will treat with acidic solution (HCL), moreover, to eliminate pigments (Decoloration) it was done by using NaOH or potassium permanganate or hydrogen peroxide or sodium hypochlorite [9][10][11][12][13].…”

After chitin production (Figure 3), the purity must be tested because any remaining impurities might cause problems related to produce products.…”

For many years, chemical pesticides have been performed to control different pests and diseases and this may be due to their broad spectrum of action, easy of application and the relatively low cost. But these chemicals have environmental risks, thus alternative control agents are needed. Chitosan is one of the novel suggested solutions to reduce the economic losses associated with chemical pesticides. Chitosan is naturally-occurring compound, as well as safe and biodegradable which obtained from certain natural sources. Chitosan have unique properties which help to control viruses, bacteria, fungi, insects, plant nematodes and other pests locally and systemically.

Root-knot nematodes (Meloidogyne spp.) have been reported to be responsible for large economic losses of agricultural crops due to their wide host range and variety of suitable climates. The control measures of these parasitic nematodes depend upon synthetic nematicides and a small number bio-based products. Chemical nematicides are eliciting adverse effects on the environment and human health. In the present study, an alternative tool, nano-chitosan was tested for the control the root-knot nematodes, Meloidogyne incognita, and Tobacco mosaic tobamovirus (TMV) in greenhouse-cultivated tomato. The effect of nano-chitosan on morphological (weight and length of shoot and root systems) and biochemical responses (Polyphenol oxidase, Peroxides, Total soluble phenol and Total protein) was assessed. The obtained results indicated that densities of Meloidogyne incognita alone or in the presence of TMV were decreased by nano-chitosan at a range of 45.89 to 66.61%, while root gall desntiy was reduced between 10.63 and 67.87%. Moreover, the density of TMV on tomato leaves singly or in the presence of M. incognita was suppressed at range of 10.26 to 65.00% after 20 days of infection, and reached up to 58.00% after 40 days of infection. However, soil application of nano-chitosan pre infection reduced TMV density only by 5.48%. Morphogenesis of tomato plants such as shoot and root systems were significantly improved. The impacts of nano-Chitosan applications on total soluble phenol, total protein, polyphenol oxidase and peroxides after 20 and 40 days of infections varied.
