Hi,
Try this, I think this will be easier if you could buy it in the USA.

Best regards.
you can buy it from India.
Please contact Dr. SG Dalvi, VSI, Pune or any person from BARC, Mumbai they are doing some experiemnts using chitosan.
with best wishes.
No use of contacting with anyone, preparing chitosan is not a matter of very much effort, just take the prawn outer part/ or crab shell, there are papers which you could download from the internet, follow that method and extract chitosan. I have done that, is very much easy.................try that....no way to spend cost.
methods of extracting chitosan you could get from Chang (1982) paper
Reference:
Chang C.T. 1982. Studies on the use of crab chitin as a water-insoluble support for the immobilization of pineapple stem bromelain and the preparation of some affinity adsorbents for proteinase. Journal of the Chinese Agriculture and Chemical society 20:45-60.
There are chitosan manufacturers in India like Mahatini in VEraval etc. Why dont you contact them.
We comparted effectiveness of 3 commercial chitosan formulations in the control of gray mold of table grapes. You can find details in:
Feliziani E., Smilanick J.L., Margosan D.A., Mansour M.F., Romanazzi G., Gu S., Gohil H., Rubio Ames Z., 2013. Preharvest fungicide, potassium sorbate, or chitosan use on quality and storage decay of table grapes. Plant Disease 97, 307-314 (full txt in on my page)
Awesome. I have followed some of the grape research utilizing chitosan, since we are examining it with some forage grasses in Texas. Very interesting for anyone interested in biocontrol/organic agriculture especially. It appears that the composition of the chitosan affects efficacy, as your results indicate.
it might be too late but I've just stumbled on your message today. I you want I can send you some powder to reconstitute yourself
